Android Question Error uploading .apk to Google Play "b4a.example already exists"

[swabygw]

I'm ready to upload my first creation from B4A to Google Play. I created the .apk file by running it in Release (obfuscated) mode. Got the following error when uploading to Google Play: "You need to use a different package name because 'b4a.example' already exists in Google Play." I did a Clean Project, searched my modules for any references like this, but can't find anything. Any ideas?

IDE menu > Project > Build Configuration > Package Name. Should be something unique .. ie com.swabygw.myappname

Thanks, I changed it as directed which, although, it solved the problem of being able to upload it to Google Play, when I recompile/run in any mode (Release, Debug, etc.), I'm getting a new error that access to the path of the .apk file is denied (I'm using B4A v5.50 and have the project stored in a Documents subdirectory). I tried right-clicking on the .apk file and reclaiming ownership of the file, but it seems that permission is denied to do that. Looks like it won't let me delete the file, either.

UPDATE: Rebooting my machine seems to have solved the problem - after reboot, the .apk file was gone and I could recompile. Thanks for your help!

I can only suggest restarting your pc / laptop .. if you have not already done so.
is your Documents folder located in a Google Drive folder ?

No - I tried copying my project to another folder (without the .apk file) and the worked for one compile and, then, the newly-created .apk was locked again. Rebooting removed the file again. Something about changing Package Name did it. It's odd...but, rebooting gets it done.
