  • Thank you for helping me. I am quite new to Android Studio, so it is possible for you to clarify a little bit more clear?
  • Sure, to change the name of the Activity, right click on the file name and there you will see an option - REFACTOR ( you can also find it in the menu on top of the studio.) Secondly, to set an activity as a default activity, go to Manifest, there you will see these lines <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> Cut and paste these under the activity you want to set as default.
