any idea how can i solve this ? you all suggestions are appreciable

Answer 1

I think this question is answered here basically look at gradle console it will show you where the problem.

Answer 2

This is usually caused by missing translation strings

to see the error run

./gradlew assemble

from your project root. you will see something like this

If your string is not translatable like fb app id, then just set translatable attribute to false

In other case, make sure you have translations in all languages you specified
