I updated the ADT and imported the projects. Unfortunately, I replaced the projects/folder. All of sudden, all the files in the folder became 0 bytes, including files in sub folders and all the current auto backups. Is there any other way to recover?and why this all 0bytes happened?
I had tested decompiling my apk from mobile with this and Differente decompilers. but, couldn't all the codes and obstucted codes. and most of the decompiler resulted errors.
I don't know what happened to your project but you can try to Restore from Local history :
