This looks like it might be an encoding problem, unless of course you expect to be seeing Chinese characters in your file. — Tim Biegeleisen, Dec 17 '18 at 05:59
Check if your local history is available for this file or else you're out of luck. — Jeel Vankhede, Dec 17 '18 at 06:05
In case it's just Android Studio getting confused about the character encoding, try opening the file with a text editor such as Notepad++. — Andreas, Dec 17 '18 at 06:06
I have tried it opening using the Notepad++ but the results are same...I am also out of luck — AgentP, Dec 17 '18 at 06:19

When files show random characters like that it usually means there was an error in the compression or convertion of the file. For example, if you take a Word document and open it in Notepad you'll see something similar to that. If you have a backup or another copy I'd recommend trying that version.

I tried Invalid Crashes but it not worked and The Second method is uninstalling and reinstalling android studio I am afraid that will also not work because when i open the file in notepad++ the code is still in unknown format – AgentP Dec 17 '18 at 06:39
if you delete .idea, .dradle, build file and import again then may be you get original code – Mayur Dabhi Dec 17 '18 at 06:55

The simple and the easy way. Go to your folder location the app>src>main>java>com> In general open your folder when you store your project then try to open the file with notepad or open code. You will find your code, copy it and delete your old file.java and past it in a new java file have the same name

first: create a backup of your project. than: you should delete android studio catch for this --> open C:\Users\plusg\AndroidStudio

for me : --> C:\Users\plusg\AppData\Local\Google\AndroidStudio2020.3

and just delete android studio catch. this folder not important just save android studio theme,font and etc.

now open your project again.
