Hi Dhara, There are a few things you can try that should help you narrow down the problem:

  1. Click on 'Android Monitor' to open it, and try running the app in the emulator. Scroll through the text and document any errors you find. If you have any errors in red, please paste them here so we can troubleshoot.

  2. Go to file>new>new project to create a new blank app. Try running that and see if it opens in the emulator. If it does work, then we know it's something wrong with the other app. If the new app has the same issue, then it could be the emulator is not configured properly (or won't work with your hardware). There are some other options we can use to test your app if that's the issue.

  3. Post your Activity code from Java>package name>MainActivity here, and we might be able to spot the issue.

Hopefully this will help shed light on the issue and you can get back to coding. Feel free to ask me if you need more help with any of this! :)
