First of all, I have read similar questions to mine and have tried out all the solutions recommended. These solutions includes:
- Invalidate cache and restart
- Sync with gradle
- Restarting Android Studio
- Clean and Build
- Change the configurations to "Nothing" on the Launcher section
- Changing the android:name on manifest file to a full package name (E.g:com.example.acer.alertbox.ActivityName)
None of these solutions seems to be working, and i keep getting the error mesage saying that "Default activity not found". I have been trying to figure this out for a week already so I hope someone will give me a new solution apart from those 6 that I have mentioned above. Below is my android manifest code which seems fine to me and that which i have checked multiple times.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</manifest>
Updated: I have uninstalled and reinstalled Android Studio, the problem is solved but another one came. The "Run" button is not doing anything when i clicked on it and i got a warning at the bottom right corner saying internal IDE error: unable to locate adb. I have downloaded the adb file and locate it on this directory C:/Acer/Users/Local/Sdk but still it doesnt change anything. I have also restart, sync the project gradle file etc. but nothing works!! Please someone help me. Below is what i got from the internal error report:
