Do this changes in your build.gradle(Module:app) file. It decreases the apk size almost (40-50)%.

android {
// Other settings

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

It reduces the size of classes.dex files and res folder.

It is recommended to that you should use webp file format instead of BMP, JPG, PNG for better compression.
