回答1:

The problem is you probably testing on lower API version then API24. So it will throw ResourceNotFoundException cause drawable does not exists for it .

So You have to have a copy of it normal drawable folder drawable . Or in all drawable-v24, drawable-v21 and drawable . put the drawable in all folder most importantly in drawable.

drawable
drawable-v21
drawable-v24

please put crashing text or you can replace this code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.android.spotsdialog.MainActivity"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/rootLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/logo"
         />
</RelativeLayout >
