Keep-alive method of application process under Android platform

Abstract

The invention discloses a keep-alive method of an application process under an Android platform. Based on a TCP long connection and an auxiliary service, the keep-alive of the process is achieved, a main application project is started as a server, a background monitoring application project serves as a client connection, heartbeats are sent to each other through certain time frequency to monitor the connection states of each other, once one of them is killed, the other party is waken up, thereby greatly improving the survival probability of the process and helping the expansion of the application service.

Description

technical field [0001] The invention relates to the technical field of application program communication, in particular to a method for keeping alive an application process under an Android platform. Background technique [0002] At present, the Android system occupies a large part of the market share. The frequency of use of mobile phones and other products that rely on the Android system is increasing. A large number of user groups have enabled many companies to see business opportunities, so various forms of apps have emerged. , and basically all apps want to be able to run in the background all the time, so as to ensure the interaction with users, especially IM (instant messaging) applications; but limited by Google, the Android system has a certain operating memory limit, in When the memory is insufficient, some low-priority applications will be killed or the user actively kills the application, resulting in a loss of connection with the server. [0003] The current pr...

Problems solved by technology

[0004] (1) Return STATR_STICK in the onstart method of the service. In this way, when the user actively kills the process, it cannot be awakened again;

[0005] (2) Simply setting the application Service as the foreground service will not be killed under normal circumstances, but some custom ROMs will be killed when the application is switched to the background, and will be killed by force stop and cannot be restarted;

[0007] (4) The Native process is started, but this method is only valid for some mobile phones with systems below 5.0, and it is completely invalid for systems above 5.0, and cannot be restarted;

[0008] (5) Use AIDL to realize inter-process communication. When processing in this way, the amount of data is huge, and the process cannot be restarted even if the user actively kills it or uses third-party software memory acceleration;
