I'm unable to set my MainActivity background from a drawable image:

android:background="@drawable/loli"

loli is my drawable name. Actually nothing special, just the usual to get a simple background. When I use it my xml, I'm getting this error while running:

Error:Error: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/home/firas/Android/Sdk/build-tools/19.1.0/aapt'' finished with non-zero exit value 42
:app:mergeDebugResources FAILED
Error:Execution failed for task ':app:mergeDebugResources'.

This can happen when gradle fails to process resources. In your case it may have happened to be an invalid image file in the drawable folder.

Please check both ways

1> check your extension & convert them .png into .jpeg

2> if that useless then delete from drawable

Please visit Android Studio Error: org.gradle.process.internal.ExecException or this link for more help Android Studio crash (aapt.exe returns 42) when I put PNG file in drawable folder

Try cleaning/rebuilding your project.

Build > Clean Project or Build > Rebuild Project

Thank you everyone for your answers the links you provide me were very useful (first one). actually the problem was not changing the image extension . because I was saving .jpeg extensions as .png from google image I think it's much suitable to keep the default extension . At least that worked for me
