App crashes on Samsung A7 Tablet how to debug?

[hires]

Thanks for this tutorial!

I finally (after much editing of version numbers and things) got Gradle to build and load this example onto my tablet. But as soon as I run the app from the home screen it just shows a black screen and then crashes. I switched the architecture to arm64-v8a since apparently that is required now by the Google Play store. But anyway...

Some helpful info to include in the instructions for us Android newbs would be:

• How to make the app start automatically when loaded over USB?
• How to connect to a debug console to see log output for dealing with crashes, etc.?

Additionally, how to run a local emulator to debug without having to copy to the device every time?
