How to build a debug android apk so BuildConfig.DEBUG is true?

Question

There are places in the code I use the flag BuildConfig.DEBUG, where can I set this flag and how can I make a debug android apk so BuildConfig.DEBUG is true?

Answer 1

where can I set this flag

It is set for you automatically when you create a debug build. You can use the Build Variants view in Android Studio to choose what build is used when you run your app from the IDE.

If you create custom build types, you can use debuggable true to mark them as debuggable, and they will have BuildConfig.DEBUG set to true as well.

Answer 2

When you run your project in Android Studio. The apk that it install in your testing device is the debug apk. You can find the apk in

YourApplication\app\build\outputs\apk
