Question

I have gone through the tutorial and did exactly what it said. I gave INTERNET,COARSE_LOCATION,FINE_LOCATION permissions. Added jar file in the libraries. It’s not working. App is getting crashed at FlurryAgent.onStartSession(). This is the code that I am using as given by them:

@Override
    protected void onStart() {
        super.onStart();
        FlurryAgent.onStartSession(MainActivity.this, MY_KEY);//MY_KEY is key given by them.
    }
    @Override
    protected void onStop() {
        super.onStop();
        FlurryAgent.onEndSession(this);
    }

Here is the stack trace:

Answer 1

It obviously crashes at runtime, you may check that your jar is exported when building apk: in project Properties > Java Build Path, go to the ‘Order and Export’ folder and fill the checkbox corresponding to your jar. And rebuild.
