Answer 1

These 4 things reduce your apk size almost 50-60%

• Replace proguard-android.txt with proguard-android-optimize.txt
• Make minifyEnabled true
• Add shrinkResources true

• Add resConfigs

  buildTypes {
      release {
          minifyEnabled true
          shrinkResources true
          resConfigs "en"
          proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
      }
  }
  

Details:

• proguard-android-optimize.txt is the more aggressive progurard configuration than proguard-android.txt.

• shrinkResources attribute will remove all the resources, those are not used anywhere in the project.

• resConfigs attribute will remove all the other localized resources while building the application. Here, it strips other than english resources.
