Phonegap build geolocation Error calling method on NPObject

问题

I have a problem with the phonegap/cordova geolocation plugin. I'm creating a application that uses the users geolocation to check if they are close to a position and then do some stuff with that.

I kept getting this error: Error calling method on NPObject. I moved the code around and created some new functions to have more specific functions and found the failing code.

I put it in a try ... catch to get better errors:

getLocation: function()
{
    try
    {
        navigator.geolocation.getCurrentPosition(this.onSuccess, this.onError);
    }
    catch(err)
    {
        console.log("Error code: "+err.code);
        console.log("Error message: "+err.message);

    }
}

But I still only get the same error Error code: undefined Error message: Error calling method on NPObject.

I'm using phonegap build and have added the plugin for geolocation.

It happens when you try, using method called from javascript interface, to interact with UI. Solve it in this way:

class mJSInterface()
{

public void myFunction()
{
  runOnUiThread(new Runnable() {

        public void run() {
            //Code that interact with UI
        }
    });

}
}
