Android Studio java file gets corrupted

Question

Unfortunaetly my laptop shutdown unproperly during coding in Android Studio. When I turned on again and tried to reload the project one class / java file was corrupted and suddenly all code was gone!

What I already tried:

• Local History -> Show History = nothing to show
• File / Invalidate Caches and Restart = no luck
• Decompiled apk, but code has been obfuscated by Proguard, so it is almost impossible to read

Weird thing is that the java file has a size but the content is empty (I already deleted "nul nul nul" characters but still no luck.

Any help or advice?

Answer 2

In my case there were 2 file 1 had XML code and other had java code. Delete the file that has XML code and rename your Java file the way it was. Solved my problem.

Answer 3

To solve the problem I would cut all the files from the project, allowing android studio to update its indices showing no files in the project tree. Soon after I move them all back then let android studio to load the files again. After loading the cache would get updated with the correct information.
