如何在 onStop/onPause 中保持进程在后台运行

Question

I need to make a keep a command running in background even if the app is in background, but I didn't find any way. I'm kind new in android developing, So...

public void RunAsRoot(String[] cmds) throws IOException {
    Process p = Runtime.getRuntime().exec("su");
    DataOutputStream os = new DataOutputStream(p.getOutputStream());
    for (String tmpCmd : cmds) {
        os.writeBytes(tmpCmd + "\n");
    }
    os.writeBytes("exit\n");
    os.flush();
}
RunAsRoot(anycommand);
public void onPause() {
   super.onPause(); 
}

您可以使用 Service 在后台执行任务： http : //developer.android.com/guide/components/services.html
