I'm working in Android Studio 2.2 RC on OSX 10.11 , and after implementing In-App Billing, after having generated my app-release.apk and having installed it on my phone, I noticed that when the purchase is successful and Ads are removed from my App, something in a secondary Activity of mine, is causing a NullPointerException and Activity is not loading.
To figure out what is causing it, I need to somehow debug the app while the In-App Purchase is active (debug.apk won't let me complete iAP) so...
How do I debug a release apk that is installed on my phone?
