some time this is caused by long directory path. – Windsail

@NoumanCh directory path mean? can you please tell me how to trace which image is causing this problem – Bijou

Answer 1

This error is caused by an incorrect/corrupted 9-patch file. They should have a transparent or opaque white border, but yours doesn't seem to have it. Try following the steps in this: https://developer.android.com/studio/write/draw9patch.html

can you please tell me what is meant by border? top most pixels? please explain – Bijou

there are so many images in android studio can you please tell me how can i check in which images is this error? – Bijou

Just above this error there should be the path of the image. If it's not there, try running with the --debug flag and checking in the full log. – Mistymisunderstand
