Question

我正在创建一个应用程序，它将在一个游戏中检查村庄的状态，我有一个问题。

我有后台服务，设定时间60秒，并重复。一切都看起来不错，但是经过一段时间（10-30分钟）后，我延迟了背景计时器的申请。

例如：执行 - 10:55:00 执行 - 10:57:10 执行 - 10:58:30 执行 - 10:59:50 执行 - 11:01:30 6.执行 - 11:03:00

这是登录应用程序的时间屏幕： Application Image

仅当我将应用程序最小化到后台时才会发生这种情况。当我在申请时，一切都很好。

    thread= new Thread(runnable);
    thread.start();

}



@Override

    /* IF YOU WANT THIS SERVICE KILLED WITH THE APP THEN UNCOMMENT THE FOLLOWING LINE */
    //handler.removeCallbacks(runnable);
    Toast.makeText(this, "Kontrolovanie dedín bolo vypnuté", Toast.LENGTH_LONG).show();
    running=false;
}

@Override
public void onStart(Intent intent, int startid) {
    Toast.makeText(this, "Kontrolovanie dedín bolo zapnuté", Toast.LENGTH_LONG).show();
}

实际代码。当移动设备与充电器断开时，延迟开始。何时移动充电器一切正常，更新60秒。一些有助于解决这个问题？
