Android中杀死所有进程

如果app是多进程的，而且要在退出主界面的时候杀死所有进程，可以试试如下方法：

private void killAllProcess() {
    ActivityManager mActivityManager = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningAppProcessInfo> mList = mActivityManager.getRunningAppProcesses();
    for (ActivityManager.RunningAppProcessInfo runningAppProcessInfo : mList) {
        if (runningAppProcessInfo.pid != android.os.Process.myPid()) {
            android.os.Process.killProcess(runningAppProcessInfo.pid);
        }
    }
    android.os.Process.killProcess(android.os.Process.myPid());
}
