Android “gps requires ACCESS_FINE_LOCATION” error

[Orby]

As of Android API 23, there is a new way to request location permissions. It doesn't look like QT5.6 beta has been updated to use this method, so I wrote a quick work around. This API 23 change might affect the camera and contacts permissions also, I'm not sure.

Before anyone says, I already have the fine location permission in my manifest:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Inside your android project, create a template. In the manifest, change:
android:name="org.qtproject.qt5.android.bindings.QtActivity"
to:
android:name="com.my_company.my_project.MyActivity"

Create the path inside your android template directory:
src/com/my_company/my_project

Now create the extended activity which requests the permissions as follows:

public class MyActivity
  extends QtActivity
{
  private static final String[] LOCATION_PERMS={
      Manifest.permission.ACCESS_FINE_LOCATION
  };

  private static final int LOCATION_REQUEST = 1337;

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

      //Ensure we can run the app
    if ( !canAccessLocation() ) 
      requestPermissions( LOCATION_PERMS, LOCATION_REQUEST );
  }

  @Override
  public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) 
  {
      //Figure out what was given to us
    switch(requestCode) 
    {
      case LOCATION_REQUEST:
        if ( canAccessLocation() ) 
          log("Access to location is granted");
        else 
          log("Access to location is denied");
        break;
    }
  }

  private boolean hasPermission(String perm) 
  {
    return ( PackageManager.PERMISSION_GRANTED == checkSelfPermission(perm) );
  }

  public boolean canAccessLocation() 
  {
    return hasPermission(Manifest.permission.ACCESS_FINE_LOCATION);
  }

  public static void log( String s )
  {
    Log.d("Radius", s );
  }
}

This "fix" was taken from the following post:

Hi,

Thanks for sharing your findings. You should also bring that to the Qt Android development mailing list. You'll find there Qt's Android port developers/maintainers. This forum is more user oriented.

Thanks for the tip, I'll do that. I'm interested to get in touch with those guys anyway to extend the default implementation of the QML Map library.

You're welcome !

Extend it Android wise or globally ?

[Orby]

I guess I'll have to see once I get in there. Ideally it would be global.

I'd like to get two finger rotation logic implemented. Also I'd like to change how the zoom works; instead of showing the user a gray square while zooming, I'd rather zoom the best fit tile.
