Detect if App is in release or debug mode in android

Make sure you are referencing your project’s BuildConfig class, not from any of your dependency libraries.

if (BuildConfig.DEBUG) {
  // do something for a debug build
}

release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            debuggable false
        }
        debug {
            debuggable true
        }
