I replaced the default splash.png images in the res/drawable folders with custom images which were named 'splash.png'.
However the build fails with the exception:
The file name must end with xml
This is thrown for the splash.png file in res/drawable-port-xhdpi.
The original file in /drawable-port-xhdpi had same name and extension, splash.png, as the current imported file, so I don't know what the issue is here.
This is the project folder view :

Any input appreciated.
