无法在服务设备上重新启动Android设备上的LocationListener

我想每三秒钟记录一次用户的位置,我想查看应用程序被杀死时以及用户重新启动设备时的位置。当应用运行或在后台运行时,我可以看到用户的位置

我的服务

insert into test (id) values('333')

Manifest.xml

public class GPS_Service extends Service {

private LocationListener listener;
private LocationManager locationManager;

String bat;
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}
private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){
    @Override
    public void onReceive(Context ctxt, Intent intent) {
        int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);
        bat=String.valueOf(level) + "%";
    }
};
@SuppressLint("MissingPermission")
@Override
public void onCreate() {
    super.onCreate();
    Log.wtf("TAG", "Service created.");
}

@SuppressLint("MissingPermission")
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.wtf("TAG", "Service started.");

    this.registerReceiver(this.mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    listener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            Intent i = new Intent("location_update");
            i.putExtra("coordinates",location.getLongitude()+" "+location.getLatitude()+ " " + bat);
            sendBroadcast(i);
        }

        @Override
        public void onStatusChanged(String s, int i, Bundle bundle) {

        }

        @Override
        public void onProviderEnabled(String s) {

        }

        @Override
        public void onProviderDisabled(String s) {
            Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(i);
        }
    };

    locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);

    //noinspection MissingPermission
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,3000,0,listener);
    return START_STICKY;
}



@Override
public void onDestroy() {
    super.onDestroy();
    if(locationManager != null){
        //noinspection MissingPermission
        locationManager.removeUpdates(listener);
    }
}
}

我的BroadcastReceiver:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.syyam.driverlocation">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <service android:enabled="true" android:name=".GPS_Service"/>
    <receiver
        android:name=".StartMyServiceAtBootReceiver"
        android:label="StartMyServiceAtBootReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
</application>

</manifest>

现在,每当我重新启动设备时,我只会在服务中看到日志记录的消息 onCreate onStartMethods ,但是看不到这些位置。重新启动后,我的public class StartMyServiceAtBootReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) { Intent serviceIntent = new Intent(context, GPS_Service.class); context.startService(serviceIntent); } }} 如下:
