设备锁定时获取位置

我正在尝试获取位置。解锁设备后,一切正常,但是锁定设备时,坐标将无法显示。

以下是我的服务示例:

public class LocationService extends Service implements GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener{

    @Override
    public void onCreate() {
        super.onCreate();

        buildGoogleApiClient();
        mGoogleApiClient.connect();

        startForeground(1131, new NotificationCompat.Builder(this, "default")
                .setContentText("App")
                .setContentTitle("App Service")
                .setSmallIcon(R.mipmap.enter_icon)
                .build());

    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, flags, startId);
        return START_STICKY;
    }

    @Override
    public void onConnected(Bundle bundle) {
        startCheckLocation()
    }

    private void startCheckLocation() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return;
        }

        LocationRequest locationRequest = LocationRequest.create();
        locationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
        locationRequest.setFastestInterval(interval);
        locationRequest.setInterval(interval);

        mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

        Intent intent = new Intent(this, LocationService.class);
        mPendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        mFusedLocationClient.requestLocationUpdates(locationRequest, mPendingIntent);
    }

    public static void start(Context context) {
        Intent intent = new Intent(context, LocationService.class);
        context.startService(intent);
    }

}

我尝试使用getBroadcast()代替getService()方法,但是它的工作方式相同。

就我而言,我是通过FirebaseJobDispatcher获取位置数据的(谷歌建议使用WorkManager,但目前仍为alpha)。 我开始每20分钟触发一次的工作,请求位置并将其存储到db。 您可以在https://github.com/firebase/firebase-jobdispatcher-android处查看FirebaseJobDispatcher的示例。

您可以使用SimpleLocation库获取当前的纬度和经度。

在build.gradle(Module:app)文件中的库下面添加

implementation 'com.github.delight-im:Android-SimpleLocation:v1.0.1'

并在服务类中使用以下代码

SimpleLocation simpleLocation = new SimpleLocation(LocationService.this);

        double lat = simpleLocation.getLatitude();
        double lon = simpleLocation.getLongitude();

不要忘记在清单文件中添加LOCATION权限。
