我正在使用 FusedLocationProviderClient 开发位置跟踪应用程序。我有一个后台服务，每 5 分钟跟踪一次电话的位置。

一切都很好，但是一旦手机空闲3到4个小时后，后台服务就会停止定位。当用户解锁手机时，跟踪再次开始。

有人可以指导我可能导致问题的原因吗？

位置更新广播接收器

public class LocationUpdatesBroadcastReceiver extends BroadcastReceiver {
public static final String TAG = "LUBroadcastReceiver";

public static final String ACTION_PROCESS_UPDATES =
        "com.orangeapp.discountnotifier.receiver.action" +
                ".PROCESS_UPDATES";

@Override
public void onReceive(Context context, Intent intent) {
    if (intent != null) {
        final String action = intent.getAction();
        if (ACTION_PROCESS_UPDATES.equals(action)) {
            LocationResult result = LocationResult.extractResult(intent);
            if (result != null) {

                List<Location> locations = result.getLocations();
                Utils.setLocationUpdatesResult(context, locations);
//                    Utils.checKOffersByLatLng(context, locations);
                    Utils.sendNotification(context, Utils.getLocationResultTitle(context, locations));
                Log.e(TAG, Utils.getLocationUpdatesResult(context));
            }
        }
    }
}
}

主要活动

private PendingIntent getPendingIntent() {

    // Note: for apps targeting API level 25 ("Nougat") or lower, either
    // PendingIntent.getService() or PendingIntent.getBroadcast() may be used when requesting
    // location updates. For apps targeting API level O, only
    // PendingIntent.getBroadcast() should be used. This is due to the limits placed on services
    // started in the background in "O".

    // TODO(developer): uncomment to use PendingIntent.getService().
//        Intent intent = new Intent(this, LocationUpdatesIntentService.class);
//        intent.setAction(LocationUpdatesIntentService.ACTION_PROCESS_UPDATES);
//        return PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent intent = new Intent(this, LocationUpdatesBroadcastReceiver.class);
    intent.setAction(LocationUpdatesBroadcastReceiver.ACTION_PROCESS_UPDATES);
    return PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

}

protected void startLocationUpdates() {

    try {
        Log.i(TAG, "Starting location updates");
        Utils.setRequestingLocationUpdates(this, true);
        mFusedLocationClient.requestLocationUpdates(mLocationRequest, getPendingIntent());
    } catch (Exception e) {
        Utils.setRequestingLocationUpdates(this, false);
        e.printStackTrace();
    }

}
