Question

我想使用setMyLocationEnabled（true）。但由于许可问题而无法使用它。

我的Android应用程序并未要求获得ACCESS_FINE_LOCATION和ACCESS_COARSE_LOCATION的许可。如果没有获得许可，它总是无法获得许可。

Android版测试设备：6.0.1
编译SDK版本和目标SDK：API-25，Android 7.1.1
构建工具版本：25.0.3
Min SDK版本：API-22，Android 5.1

AndroidManifest.xml中添加了以下权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="com.google.android.providers.gsf.permisson.READ_GSERVICES"/>
<uses-permission android:name="edu.bloomu.huskies.tsc71523.skatelogger.MAPS_RECEIVE"/>

MapsActivity.java：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

}
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    LatLng sydney = new LatLng(0, 0);
    mMap.addMarker(new MarkerOptions().position(sydney).title("TestLocation"));

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
        Log.e("LOCATION", "ACCESS_FINE_LOCATION-------Successful");
        mMap.setMyLocationEnabled(true);
    }
    else {
        Log.e("LOCATION", "ACCESS_FINE_LOCATION-------Failed");
    }

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
        Log.e("LOCATION", "ACCESS_COARSE_LOCATION-------Successful");
        mMap.setMyLocationEnabled(true);
    }
    else{
        Log.e("LOCATION", "ACCESS_COARSE_LOCATION-------Failed");

    }
}
}

从Android Marshmallow（6.0）开始，如果您的目标是API级别23或更高，则必须使用新的权限模型（请求权限）。
