Describe the bug When starting app that has android.content.ContentProvider as in the simplest way I could find Android explodes with RuntimeException as below:

Process: org.nativescript.testprovider, PID: 8272

To Reproduce Extend android.content.ContentProvider with any content and try to start the app.

Expected behavior

• App does not crash
• Content provider query is being called to get the directory

Sample project Demo project based on "Plain JavaScript -Hello World" template

Additional context I managed to have it working using pure Android without problems and I copied the fragments of AndroidManifest.xml from it.

@mrfuxi, thanks for reporting this issue. Implementing content providers in javascript is unfortunately not supported at the moment. Content providers are instantiated very early in the application lifecycle (prior to creating the context) and the NativeScript runtime is not yet initialized at this stage.
