Find the problem

You can Analyse APK from Android Studio. This shows you the various files in their directories and their sizes, both absolute and relative to the whole APK:

Just remove them from your project.

Use Vector Images

Vector Drawables provide one sharp image for all resolutions, greatly reducing the size for your graphics. As usually, you can use these for icons etc, but not for Photos. Non-vectorized images can be reduced with trimage.

proguard minify

Add the following to app/build.gradle to enable proguard to reduce unused classes from your project:

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