Unable to open project file

I’m unable to open my saved project file …After export my file to an android apk.
How to open it ?

You can open your android apk on and android mobile

Thank you for your tips. but i want to open my project file and update it…
After export project can i open the project file on Gdevelop app. and reuse it

Check in your project folder if you have a recent file with extension .json.autosave.
If there is one, copy-paste it, remove the .autosave from the copy, and try loading that file.
What version of GDevelop do you use?

Many Many
Thank you sir for your support, It"s working …I’m using Gdevelop 5.
