java - 强制停止我的包后，Android 正在终止我的前台服务

Question

我已经为此苦苦挣扎了 2 周。

我正在开发一款控制通话时长的应用。

我收到一个广播，我在其中启动前台服务以挂断电话。

但在五分钟或更长时间后，android 强制停止我的程序包然后终止我的进程，这导致服务崩溃 - 我认为 - (不知道为什么)没有崩溃消息或任何类型的错误。

它就这样消失了。

它会安排重新启动，但不会再次启动该服务。

这是日志

 12-29 00:28:52.857 619-619/? I/ActivityManager: Force stopping package club.androidy.callcontrolfree appid=10006 user=0

使用 adb shell dumpsys 我得到了这个确保我的服务是具有正确优先级的前台服务

我不会将我的服务绑定(bind)到任何 Activity

我这样开始我的服务:

            Intent srvIntent = new Intent(context, PhoneCallService.class);
            context.stopService(srvIntent);
            PhoneCallService.stopService = false;
            context.startService(srvIntent);

这是我的onStartCommand:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Context context = getApplicationContext();
    String txtNotificationTicker = context.getString(R.string.strNotificationTicker);
    String txtNotificationTitle = context.getString(R.string.strNotificationContexTitle);
    String txtNotificationText = context.getString(R.string.strNotificationContexText);
    String ns = Context.NOTIFICATION_SERVICE;

    Intent cancelIntent = new Intent(this, StopServiceReceiver.class);
    PendingIntent pendingIntentCancel = PendingIntent.getBroadcast(this, 0, cancelIntent
            , PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Action action =
            new NotificationCompat.Action
                    .Builder(R.drawable.ic_cancel
                    , context.getString(R.string.stop_service), pendingIntentCancel)
                    .build();

    Intent mIntent = new Intent(this,MainActivity.class);
    int HELLO_ID = 1;
    PendingIntent pendingIntent = PendingIntent.getActivity(this, HELLO_ID, mIntent , 0);
    this.mNotificationManager = (NotificationManager) getSystemService(ns);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

    Notification notification = builder
            .setContentIntent(pendingIntent)
            .setContentTitle(new StringBuilder(String.valueOf(txtNotificationTitle)))
            .setSmallIcon(R.drawable.ic_launcher)
            .setLargeIcon(getBitmap(context, R.drawable.ic_launcher))
            .setContentText(new StringBuilder(String.valueOf(txtNotificationText))
                    .append(": ").append(PHONE_NUMBER).toString())
            .setWhen(System.currentTimeMillis())
            .setPriority(NotificationCompat.PRIORITY_MAX)
            .addAction(action)
            .build();

    notification.flags |= Notification.FLAG_NO_CLEAR;
    startForeground(1, notification);
    this.pt = new PhoneThread();
    this.pt.start();
    return Service.START_STICKY;
}

我正在像这样获取唤醒锁

        if (PhoneCallService.sCpuWakeLock == null) {
                PhoneCallService.sCpuWakeLock = ((PowerManager)
                        context.getSystemService(Context.POWER_SERVICE))
                        .newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"CCF");
                PhoneCallService.sCpuWakeLock.acquire();
            Log.e("androidy","wacklock acquired");
            }

我已经尝试过很多来自 SO 和 google issues 的解决方案，但没有一个对我有用。

我看到并尝试了所有这些:

Foreground service killed by OS

Foreground service gets killed every time

Android foreground service being killed under certain conditions

Foreground Service being killed on Notification click

Foreground service being killed by Android

保留该应用的用户仅占总安装量的 30%。

我做错了什么？

编辑:

如果您有同样的问题，请检查手机设置中的省电选项 如果您的手机有此功能，它会在屏幕关闭后终止您的应用程序，并且不允许它在后台运行.

原始答案:经过大量搜索我自己解决了

原来我的应用是耗电的，如下图所示

因此，当屏幕上没有任何 Activity 以节省电量时，android 会在 5 分钟后强制停止它。

我解决了功耗问题，一切正常。
