You can get Size of apps without AIDL Files -------> Kotlin Language

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

    val intent = Intent(Intent.ACTION_MAIN)
    intent.addCategory(Intent.CATEGORY_LAUNCHER)  
        
    val list = packageManager.queryIntentActivities(intent,0)
            
    // Set adapter to LIST VIEW
    listView.adapter = getApps(list)
 }
       
 private fun getApps(List: MutableList): List {
            
     val list = ArrayList()
      for (packageInfo in List) {
                      
         val packageName = packageInfo.activityInfo.packageName
           // return size in form of Bytes(Long)             
    val size = File(packageManager.getApplicationInfo(packageName,0).publicSourceDir).length()
          
          val item = AppData(Size)
            list += item
      }
   return list
   }
}
 // Make Data Class
data class AppData(val size: Long)

Remember to convert it in MB from Bytes
