None of these suggestions worked for me, because Android was appending a sequence number to the package name to produce the final APK file name (this may vary with the version of Android OS). The following sequence of commands is what worked for me on a non-rooted device:

1. Determine the package name of the app, e.g. com.example.someapp. Skip this step if you already know the package name.

   adb shell pm list packages

   Look through the list of package names and try to find a match between the app in question and the package name. This is usually easy, but note that the package name can be completely unrelated to the app name. If you can't recognize the app from the list of package names, try finding the app in Google Play using a browser. The URL for an app in Google Play contains the package name.

What is this all about?

This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.
