RunTime Error at setContentView(R.layout.activity_main)

Question

So I'm getting an exception on my Android App, that I have no idea where comes from. And yes my code is a complete mess now from trying to fix it

MainActivity.kt

class MainActivity : AppCompatActivity() {
    var navigationDrawerIconsList: ArrayList<String> = arrayListOf()
    var images_for_navdrawer= intArrayOf(R.drawable.navigation_allsongs,R.drawable.navigation_favorites,R.drawable.navigation_settings,R.drawable.navigation_aboutus)
    object statified{
        var drawerLayout: DrawerLayout?=null
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val toolbar = findViewById<Toolbar>(R.id.toolbar)
        setSupportActionBar(toolbar)
        MainActivity.statified.drawerLayout= findViewById(R.id.drawer_layout)
        navigationDrawerIconsList.add("All Songs")
        navigationDrawerIconsList.add("Favourites")
        navigationDrawerIconsList.add("Settings")
        navigationDrawerIconsList.add("About Us")

        val toggle = ActionBarDrawerToggle(this@MainActivity, MainActivity.statified.drawerLayout,toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
        MainActivity.statified.drawerLayout?.setDrawerListener(toggle)
        toggle.syncState()

        val mainScreenFragment = MainScreenFragment()
        this.supportFragmentManager
                .beginTransaction()
                .add(R.id.details_fragment,mainScreenFragment,"MainScreenFragment")
                .commit()
        var _navigationAdapter= NavigationDrawerAdapter(navigationDrawerIconsList,images_for_navdrawer,this)
        _navigationAdapter.notifyDataSetChanged()

        var navigation_recycler_view = findViewById<RecyclerView>(R.id.navigation_recycler_view)
        navigation_recycler_view.layoutManager = LinearLayoutManager(this)
        navigation_recycler_view.itemAnimator=DefaultItemAnimator()
        navigation_recycler_view.adapter = _navigationAdapter
        navigation_recycler_view.setHasFixedSize(true)
    }

    override fun onStart() {
        super.onStart()
    }
}

Answer 1

I think the drawable that you are setting in your ImageView is too large. Please pick an image with smaller size to avoid the OutOfMemoryError .

Please check the @drawable/title size as mentioned in the comment.

To get the idea about the image sizes, I would recommend to read this beautiful article here .
