on Android 4.4, the child process is created by the parent process. According to the process id, the child process manually kill the parent process, but the child process is still running and is not killed. As a result, the child process is not re-created when the parent process is pulled up again. How to deal with it at the system level and kill the child process when the parent process dies at the same time.

prctl(PR_SET_PDEATHSIG, SIGKILL); Previous: How does java move 2 decimal places to the left?
