我建立了内存优化的Andr​​oid应用程序。我可以成功地得到使用此回答正在运行的进程（和它们的PID）的列表。不过，我不明白的方式通过PID杀死他们或他们的后台服务。

I am building an Android app for RAM optimization. I can successfully get the list of running processes (and their PIDs) using this answer. However, I don't see a way to kill them or their background services by PID.

推荐答案

这竟然是一些很基本的：

It turned out to be something very basic:

ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);

for (RunningAppProcessInfo pid : am.getRunningAppProcesses()) {
    am.killBackgroundProcesses(pid.processName);
}
