客户端必须具有ACCESS_FINE_LOCATION权限才能请求priority_high_precision位置运行时错误

Question

LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);

这是我的完整代码。

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,LocationListener {

private static final String TAG ="hello" ;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;


public Location mLastLocation=null;


public final int MY_PERMISSIONS_REQUEST_COARSE_LOCATION=0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (mGoogleApiClient==null){
        mGoogleApiClient= new GoogleApiClient.Builder(this)

                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

    mLocationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(10 * 100)        // 10 seconds, in milliseconds
            .setFastestInterval( 1* 100); // 1 second, in milliseconds

    }









@Override
public void onConnected(@Nullable Bundle bundle) {


    int permissionCheck = ContextCompat.checkSelfPermission(this,
            Manifest.permission.ACCESS_FINE_LOCATION);
    int permissionCheck1 = ContextCompat.checkSelfPermission(this,
            Manifest.permission.ACCESS_COARSE_LOCATION);
    if (permissionCheck != PackageManager
            .PERMISSION_GRANTED && permissionCheck1 != PackageManager.PERMISSION_GRANTED) {

        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.ACCESS_FINE_LOCATION)) {

            // Show an explanation to the user *asynchronously* -- don't block
            // this thread waiting for the user's response! After the user
            // sees the explanation, try again to request the permission.

        } else {

            // No explanation needed, we can request the permission.

            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},

        TextView mLongitudeText =(TextView)findViewById(R.id.textView2);

        mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
        mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));

        Log.i("Location Info", "Location achieved!");

    } else {



        Log.i("Location Info", "No location :(");

    }

此外，我已经在清单文件中给予了许可。

RequestPermissions()是异步的。当它返回时，您还没有权限。用户甚至没有被询问权限。

您需要在两个地方执行位置逻辑：

先行，如果您已经有权限
