[0053] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] It should be noted that the descriptions involving "first", "second", etc. in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0055] In the description of the present invention, it should be understood that the numerical labels before the steps do not identify the sequence before and after the execution of the steps, but are only used to conveniently describe the present invention and distinguish each step, and thus cannot be understood as a limitation to the present invention.

[0056] Term explanations of the present invention:

[0057] Single-application mode, which is used to use the graphical user interface (main interface) of a certain application (such as LanXin) as the system desktop of the Android device 10. In some other embodiments, the single-application mode can also be used to use the graphical user interface of other desktop applications other than the system default desktop application as the system desktop of the Android device 10.

[0058] After research, the present invention believes that the single-application mode can be implemented in the Android system in the following two ways:

[0059] (1) If the single-application mode is customized based on the Android system, it is necessary to modify at the source code level of the Android system. After the Android system is compiled, the Android system is then flashed into the Android device 10 for running.

[0060] (2) Based on the software development kit provided by the Android system manufacturer to the application developer side, the development and application of the single-application mode are realized.

[0061] However, the above approach has the following drawbacks: (1) When the single-application mode based on system customization needs to be modified again, it is necessary to modify it again at the source code level of the Android system and then flash the modified Android system into the Android mobile terminal; developing the single-application mode according to different projects involves a large amount of work, which affects the development and application efficiency of the single-application mode. (2) When implementing the single-application mode based on the software development kit provided by the system manufacturer, there are certain requirements for the model of the Android device 10, with low compatibility and relatively low development and application efficiency of the single-application mode.

[0062] In view of this, the present invention provides a method for implementing a single-application mode in an Android system, which has at least some or all of the following advantages: (1) It is applicable to implementing the locking and cancellation of the single-application mode for all devices based on the Android system. (2) No changes need to be made to the system. (3) High compatibility. (4) In engineering use, it can greatly reduce the development workload and the communication cost between the system manufacturer and the application developer.

[0063] It should be noted that one of the key points of the present invention is to implement the logic of enabling and disabling the single application in the application, obtain the execution permission through system signature, decouple from the system, and no modification is required for the system. The second key point is reversibility, and it can be decided at any time whether to set it to the single-application mode or restore it to the original system mode according to the control instruction.

[0064] The above method will be introduced in detail through one or more embodiments below.

[0065] As Figure 1 shown, the single-application mode processing method based on an Android device described in the present invention is executed in the Android device 10. The Android device 10 can be a mobile phone, a tablet computer, a laptop computer, a virtual host, etc.

[0066] The embodiment of the present invention is to introduce the switching between the original system desktop and the target system desktop in the single-application mode. One or more embodiments will be provided below to specifically introduce the single-application mode processing solution based on an Android device.

[0067] Embodiment 1

[0068] Please refer to Figure 2 to show the overall step flow chart of the single-application mode processing method based on an Android device according to the embodiment of the present invention in the enterprise application scenario to meet the usage requirements of enterprises for Android devices.

[0069] The following will be described by taking the Android device 10 as the execution subject for illustration, specifically as follows:

[0070] As shown Figure 2 in the figure, the single-application mode processing method based on the Android device may include steps S100 to S120, where:

[0071] Step S100, obtaining a first instruction for entering the single-application mode; wherein, the single-application mode is used to switch the Android device 10 from the original system desktop to the target system desktop, the original system desktop is the system default desktop of the Android device 10, and the target system desktop is the graphical user interface of the target application.

[0072] The original system desktop accommodates icon components (app widgets) of multiple third-party applications (such as, LanXin, Google Chrome, WeChat, DingTalk). Users can enter the corresponding third-party applications through these icon components on the original system desktop. After the Android device 10 enters the single-application mode, the Android desktop switches from the original system desktop to the target system desktop. The target system desktop uses the graphical user interface (such as the main interface) of the target application as the system desktop of the Android device 10 (i.e., the only interface entry).

[0073] In an exemplary embodiment, the Android device 10 can generate the first instruction in the following two ways:

[0074] (1) Generating the first instruction through a single-application mode switch button.

[0075] For example, when the Android device 10 receives an activation trigger operation (such as a physical or virtual key operation) on the single-application mode switch button of the Android device 10, it generates the first instruction to indicate entering the single-application mode.

[0076] (2) Generating the first instruction when the Android device 10 meets a preset trigger condition.

[0077] For example, the preset trigger condition can be set to generate the first instruction for the Android device 10 to enter the single-application mode at 9:00 am every day, which helps to quickly activate the single-application mode and is especially applicable to enterprise scenarios.

[0078] Step S120: According to the first instruction, execute the target desktop code of the target system desktop and stop running the original desktop code of the original system desktop to enter the single-application mode, so as to switch the Android device 10 from the original system desktop to the target system desktop; wherein, the target desktop code has the permission to control entering and exiting the target system desktop, and the permission is obtained in advance based on the system signature of the Android device.

[0079] To effectively improve the efficiency of desktop application switching, please refer to Figure 3 , Step S120 can be obtained through the following operations, where: Step S122: According to the first instruction, add a first status value to the target desktop code of the target system desktop, and the first status value indicates that the target system desktop is in an allowed startup state; Step S124: According to the first instruction, add a second status value to the original desktop code of the original system desktop, and the original desktop code is used to control entering and exiting the original system desktop, and the second status value indicates that the original system desktop is in a prohibited startup state; and Step S126: According to the first status value and the second status value, execute the target desktop code and stop running the original desktop code to enter the single-application mode, so as to switch the Android device 10 from the original system desktop to the target system desktop. In the embodiment of the present invention, by setting the first status value and the second status value, the goal of switching the original system desktop to the target system desktop in the single-application mode is achieved.

[0080] In an exemplary embodiment, in order to ensure that the target system desktop has the permission to be displayed as the system desktop of the Android device 10, it is necessary to pre-configure multiple desktop property tags for the target system desktop during the code development stage. Exemplarily, the Android device 10 loads the target system desktop by running the target desktop code of the target system desktop, where the target desktop code is used to control entering and exiting the target system desktop. The target desktop code includes the code of the entry desktop component of the target application, and the entry desktop component is used to load the graphical user interface of the target application on the Android device 10. Please refer to Figure 4 , The Android device 10 also performs the following operations, where: Step S300: Pre-create an alias for the entry desktop component, and the alias for the entry desktop component is used to execute each function in the entry desktop component and execute the new functions in the single-application mode through the entry desktop component; and Step S302: Add multiple desktop property tags to the alias for the entry desktop component to determine that the target system desktop has the permission to be the system desktop of the Android device 10 according to the multiple desktop property tags.

[0081] For example, configure an activity-alias (i.e., the entry desktop component alias) for the entry Activity of the target application (i.e., the entry desktop component). As an alias of an existing entry Activity, the activity-alias can quickly call the Activity through the label declaration of the activity-alias, and multiple desktop property labels are added to the activity-alias. For example, android.intent.category.LAUNCHER (which determines whether the application is displayed in the program list and is launched as the main menu) and android.intent.category.HOME (which determines whether it can be launched as an option for the desktop application), etc. Only the application with desktop property labels has the permission to be loaded as the system desktop on the Android device 10. Therefore, pre-configuring multiple desktop property labels for the activity-alias corresponding to the target system desktop enables the target system desktop of the target application to have the permission to be the system desktop of the Android device 10, which can better support the subsequent development of the target desktop code related to the single-application mode.

[0082] To ensure that the target desktop code can run effectively on the Android device 10, the method further includes the step of pre-testing the target desktop code sent by the application developer during the code development stage. Please refer to Figure 5 , and this test step includes steps S400 to S404, where: Step S400, obtain the permission to control the execution of the target desktop code according to the system signature of the Android system in the Android device 10; Step S402, test the target desktop code according to the permission; and Step S404, determine that the target desktop code enters the test-passed state or determine that the target desktop code enters the code-modification state according to the test result.

[0083] For example, obtain the system signature provided by the Android system manufacturer. This system signature can grant the execution permission of the target desktop code corresponding to the target system desktop in the Android system, so as to complete the development and application of the target desktop code through this permission. Moreover, the implementation logic and process of enabling and disabling the single-application mode are written into the target desktop code corresponding to the target application in the form of code, decoupled from the system, and no modification is required at the source code level of the Android system. That is, directly modify the target desktop code at the application level without reflashing the Android system on the Android device; in engineering use, it can greatly reduce the development workload of the system and shorten the development cycle of the single-application mode; when developing, the application developer only needs to obtain the system signature of the Android system manufacturer to obtain the authorization of the execution permission of the target desktop code, and then can carry out subsequent code development and application, greatly reducing the communication cost between the Android system manufacturer and the application developer; it is convenient to quickly test, develop and apply the target desktop code.

[0084] In an exemplary embodiment, in order to quickly start the target system desktop and switch the original system desktop to the target system desktop, please refer to Figure 6 , step S122 may further include steps S500 to S502, where: step S500, determine the specified component according to the component name of the entry desktop component alias, and the specified component includes the entry desktop component and the entry desktop component alias; and step S502, set the first attribute state of the specified component to the first state value, and the first state value indicates that the desktop permission of the target system desktop is allowed to be enabled.

[0085] In the Android device 10, by calling the system method: public abstract void setComponentEnabledSetting(ComponentName componentName, int newState, int flags) to set the enabled attribute (the attribute indicating whether it is allowed to be enabled, that is, the first attribute state) of the specified component to true (allowed to be enabled) or false (not allowed to be enabled) to determine whether to enable the target system desktop as a desktop application. Among them, public abstract void setComponentEnabledSetting(ComponentName componentName, int newState, int flags) represents the method for obtaining the state of the component; ComponentName represents the component name; newState represents the new state of the component, and the new state of the component can be set to:

[0086] The prohibited enabled state (COMPONENT_ENABLED_STATE_DISABLED) or the permitted enabled state (COMPONENT_ENABLED_STATE_ENABLED); flags represents a behavior tag, and the corresponding value of the behavior tag can be DONT_KILL_APP or 0. Among them, DONT_KILL_APP indicates that the application containing this component is not cleared, and 0 indicates that the application containing this component is cleared; int represents a data format.

[0087] In the embodiment of the present invention, ComponentName is correspondingly set to the component name of the entry desktop component of the target application; the first attribute state is set to COMPONENT_ENABLED_STATE_ENABLED (i.e., the first state value), that is, the first state value corresponds to true; flags is set to DONT_KILL_APP. By setting the first attribute state as above, the rapid enablement of the target system desktop is achieved. Since the present invention realizes the Android device 10 entering the single-application mode by setting the first attribute state of the component name of the target application, it does not require the Android system manufacturer to provide a software development kit for developing the single-application mode, nor does it involve the model of the Android device 10. Therefore, the single-application mode processing method based on the Android device described in the embodiment of the present invention has no requirements for the model of the Android device 10, can be applied to any Android device 10 based on the Android system, has high compatibility, and is not restricted by the software development kit; and the target application can be set according to the actual project requirements, and there is no problem of adaptability.

[0088] In an exemplary embodiment, in order to quickly disable the original system desktop, please refer to Figure 7 , step S124 may further include steps S600 to S602, where: step S600, determining the desktop package of the original system desktop through the desktop package name, and the desktop package name is the name of the desktop package of the original system desktop; and step S602, setting the second attribute state of the desktop package to the second state value, and the second state value indicates that the desktop permission of the original system desktop is prohibited from being enabled.

[0089] In the target application of the Android device 10, the original system desktop is disabled by calling the method public abstract void setApplicationEnabledSetting(String packageName, int newState, int flags). Among them, public abstract void setApplicationEnabledSetting represents the method for obtaining the status of the application; Enabled represents the status of the second attribute; packageName represents the name of the desktop package corresponding to the application; newState represents the new status of the desktop package; and String represents a data format.

[0090] In the embodiment of the present invention, packageName is correspondingly set to the name of the desktop package of the original system desktop; the second attribute status is set to PACKAGE_ENABLED_STATE_DISABLED (i.e., the second state value); and flags is set to DONT_KILL_APP. Through the setting of the above second attribute status, the rapid disabling of the original system desktop is achieved.

[0091] In an exemplary embodiment, in order to achieve a quick exit from the single-application mode, as Figure 8 shown, the method further includes steps for exiting the single-application mode, including: Step S700, obtaining a second instruction for exiting the single-application mode; Step S702, determining the desktop package of the original system desktop based on the desktop package name according to the second instruction; Step S704, setting the second attribute status to a third state value, where the third state value indicates that the desktop permission of the original system desktop is allowed to be enabled; Step S706, setting the first attribute status to a fourth state value, where the fourth state value indicates that the desktop permission of the target system desktop is prohibited from being enabled; and Step S708, executing the original desktop code and stopping the execution of the target desktop code according to the third state value and the fourth state value to exit the single-application mode, so as to switch the Android device 10 from the target system desktop to the original system desktop.

[0092] In this embodiment, the second attribute state of the desktop package of the original system desktop is set to PACKAGE_ENABLED_STATE_ENABLED (i.e., the third state value); the flags are set to DONT_KILL_APP; the first attribute state of the alias of the entry desktop component of the target application is set to COMPONENT_ENABLED_STATE_DISABLED (i.e., the fourth state value), that is, the first state value corresponds to false; the flags are set to DONT_KILL_APP. Through the above setting of the second attribute state, the quick enablement of the original system desktop is achieved; through the above setting of the first attribute state, the quick disablement of the target system desktop is achieved, that is, the logic code implemented for the single-application mode in the embodiment of the present invention converges in the target application, and can cooperate with the first instruction or the second instruction to determine whether to set it to the single-application mode or restore it to the original system desktop. According to the first instruction or the second instruction, the quick switching between the target system desktop and the original system desktop in the single-application mode can be achieved, so that the switching between different system desktops is reversible.

[0093] In an exemplary embodiment, to ensure that the default system desktop or the target system desktop can be effectively loaded each time the Android device 10 is powered on. Exemplarily, the Android system in the Android device 10 includes a desktop application loading component, and the desktop application loading component includes a plurality of desktop property tags. The desktop application loading component is used to load the original system desktop or the target system desktop after the Android system is powered on. Please refer to Figure 9 , the method further includes a control step for the desktop application loading component, and the control step includes: step S800, obtaining the current system version of the Android system; and step S802, if the version number of the current system version is higher than the version number of the preset system version, then setting the loading attribute state of the desktop application loading component to the fifth state value, and the fifth state value indicates that the system desktop loading is allowed to start, so that the desktop application loading component loads the original system desktop or the target system desktop after the Android system is powered on.

[0094] The version number of the preset system version is set to Android 7.0. The desktop application loading component is com.android.settings.FallBackHome, which is used to load and start the system desktop application after the Android system is powered on or restarted. Therefore, it is necessary to ensure that the desktop application loading component remains always-on, that is, to ensure that the loading property status of the desktop application loading component is the fifth status value; the loading property status indicates that the desktop application of the Android device 10 is in a state with the loading permission to load and start the system desktop application; the fifth status value indicates that the system desktop is allowed to be loaded and started. If the loading property status of the desktop application loading component indicates that the system desktop is prohibited from being loaded and started, the Android system will always be in the boot animation interface after being powered on. Exemplarily, when the current system version of the Android system is the Android 8.0 version, it is considered that the Android 8.0 version is higher than the Android 7.0 version, and the desktop application loading component is set to be always-on to ensure that the Android device 10 can normally and effectively load and start the system desktop.

[0095] To make the present invention easier to understand, as Figure 10 , the following provides the overall step flowchart for entering or exiting the single-application mode.

[0096] ① According to the instruction, determine whether to enable the single-application mode.

[0097] ② If the determination result in step ① is to enable the single-application mode, add the first property status to the target system desktop.

[0098] ③ After step ②, save the package name of the desktop of the original system desktop.

[0099] ④ After step ③, set the original system desktop to prohibit the operation of the original system desktop application, then the single-application mode is enabled.

[0100] ⑤ If the determination result in step ① is not to enable the single-application mode, obtain the package name of the saved original system desktop (Launcher).
