Android App Showing Two Toolbars Issue fix

While working on an Android Application, when I ran my App on Emulator, I saw that there were two ToolBars displayed instead of one! I could figure out the reason and here is what the issue was

By default when you create an Android Application using a template - it adds a Toolbar as default, If you change your application layout and add your own Toolbar - it will display two of them, I was able to remove the default one by doing the below steps,

1. Go to res -> values -> themes
2. Open themes.xml file,
3. Add the below two lines under style tag,

   <item name="windowActionBar">false</item>
   <item name="windowNoTitle">true</item>

4. Now run the App you should see only one Toolbar

Note: Do the same changes for the dark them styles.xml file as well.
