I'm building an application that has a shared library and two applications that share this library. As soon as the application starts the logcat shows D/AndroidRuntime: Shutting down VM. If I debug the application it does not launch my MainActivity (LoginActivity). The application crashs after return from attachBaseContext(Context base) in the Application Class.
This is not a simple case of NPE, the problem is that the VM is Shutting down and the only debuggable part is the Global.attachBaseContext that runs OK and after that the Logcat message is shown.
LOGCAT
I/MultiDex: VM with version 2.1.0 has multidex support

Note that the API key is linked to the encryption key used to sign the APK.

sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.
