Question

我正在尝试在我的应用程序加载地图时显示基本的setMyLocation按钮但每次我这样做时应用程序崩溃并说java.lang.SecurityException：我的位置需要权限ACCESS_FINE_LOCATION或ACCESS_COARSE_LOCATION 在android.app.ActivityThread.performLaunchActivity（ActivityThread.java:3288）我有清单中包含的必要权限

    public class MainActivity extends AppCompatActivity {
    public GoogleMap map;
    Location location;
    //double lat, longit;


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

        map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

        map.setMyLocationEnabled(true);
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }




    }
