Cannot find projects

I cannot find projects I worked on around a year ago.

I have a development app on my phone and want to continue working on it. Wondering if I can somehow open project using the app?

Did you use or ?

If you have an APK, download APK Editor Studio:

Open your APK in the studio. Via the 'Tools' menu, select 'View Signatures'. This will reveal the Google account used.
