Problems solved by technology

However, the Android 2.1 version was released in early 2010, and the time for hardware manufacturers following the Android system to directly upgrade to version 2.3 is limited, and the development cost is also high
In addition, when transplanting the dual-camera frame part of version 2.3 to version 2.1, there are many modifications to the frame part, and the workload is relatively large

Embodiment Construction

[0024] According to the existing architecture of the Android 2.1 system, the application operation flow chart after realizing dual camera support is as follows figure 1 shown.

[0025] according to figure 1 As shown in the process, there are mainly the following steps to realize dual camera support:

[0026] Step 1: Add preference settings resources

[0027] SharedPreferences is a utility class for storing simple data in Android. It provides a lightweight data storage method by storing simple data types in the private directory of the application ( / data / data / $PACKAGE_NAME / shared_prefs / ) defined by key-value pairs (key-value) xml file.

[0028] Android 2.1 Camera application (package / apps / Camera directory, hereinafter marked as $CAM_PACK) has already adopted this method to record some configuration parameters of the camera. To realize dual cameras, only a new parameter needs to be added on the original basis—the one currently in use camera. The dual camera is divided into...

Abstract

The invention provides a simple and efficient method for supporting dual cameras in Android 2.1 version, which can be applied to an intelligent mobile phone, a tablet computer and other electronic products using the system and requiring the support for the dual cameras. The method comprises the following steps of: adding preference settings resources; applying acquisition system permission; adding configuration file key value pairs; acquiring and setting a hardware abstract layer; and applying monitoring and changing the setting. In the method, by using the traditional data storage mechanism and attribute system of an Android system, the support for the dual cameras in the Android 2.1 version can be realized without changing the traditional framework code, so that the method is very convenient and efficient to realize. The principle and the mechanism of the realization method are supported by a mainstream version of the Android so as not to be limited by the current Android version, even can be still continuously used in the subsequent version.

Description

【Technical field】 [0001] The invention relates to a mobile terminal operating system, in particular to a method for supporting dual cameras in Android. 【Background technique】 [0002] Statistics released by the China Internet Network Information Center show that as of now, the number of people surfing the Internet through mobile phones in my country has reached 277 million, and the proportion of Internet users using mobile phones to access the Internet has climbed to 65.9% of the total number of Internet users. These figures all indicate the mobile Internet era. Full arrival. [0003] In the first half of 2010, with Apple's launch of the epoch-making iPad, tablet computers have become a high-profile mobile terminal in the market, and together with smart phones, they have become an important boosting force in the mobile Internet era. [0004] With the advent of the 3G era, the network transmission speed has been greatly improved compared with the previous 2G (GSM) era. The f...
