Abstract: A method for identifying an Android system drawing thread, for a client based on an Android operating system, including following operations: creating a plurality of threads, wherein the threads include one or more of a main thread of an application process, a hardware rendering thread of an Android system, and a customized thread; performing cross-process communication through the threads, applying for a graphics buffer area, and calling a QueueBuffer function of BufferQueue to submit a graphic content drawn by the client to a system graphics buffer area; identifying a thread task according to a state of a process state switching, identifying a current running thread, marking a current task_struct of the thread as ui_thread, and obtaining a drawing thread state; and identifying the thread task according to the state of the process state switching, if the thread is not the current running thread, resetting the drawing thread state.

Abstract: A process communication method and apparatus, a storage medium, and a mobile terminal. The method comprises: when a system process needs to communicate with an application process, determining whether an idle communication thread is present in a thread pool of the application process (101); if no idle communication thread is present in the thread pool of the application process, creating a first target communication thread (102); and communicating with the system process using the first target communication thread (103). By creating a target communication thread in a thread pool of an application process, abnormalities such as a frozen screen, restart and stuttering of a mobile terminal are avoided.
