Sometimes android studio doesnt install the new apk while running. It bring the previous activity to front.

Follow the steps.

  1. Make sure you have the image in drawable folder.
  2. Rebuild the application. Build->Rebuild application
  3. Uninstall the application from the emulator or phone(Testing device).
  4. Run the application.

When you put your image in drawable folder. Aptly choose for which screen density you want which picture.

As there are drawable-ldpi,drawable-mdpi,drawable-hdpi etc... and a normal drawable folder. If android studio cant find a image in these qualifier drawable folder then it will look up in the normal drawable folder.

Use an ImageView as the first element in your RelativeLayout. Then, set your drawable to src of the ImageView and set scaleType to fitXY so that your background is shown properly.
