Compilation failed to complete in android studio

Question

When I build an apk it gives an error "Compilation failed to complete"

Is there anything wrong with the module?

Answer 1

Yes. There's something wrong somewhere (haha).

Look at this line

Error while merging dex archives: D:\WajabatApps\Wajabat\app\build\intermediates\trans

This line is giving you the exception. But this is because of this line error:

program type already present: com.abdalltif.wajabatonline.BuildConfig

You get this error when you have a library module which has the same package name as the app module. Try to change the package name. This should work.
