Error: attempting to parent and popup a dialog that already has a parent.
I spent so much time trying to fix this... and still nothing. I did everything what the docs said. I installed openJDK 11, android studio, sdk's, I made a debug keystore. And always this error. Please help.
You're probably going to have to give a lot more information than that. Where are you getting this error, for example? What are you trying to do? If the error happens when you export, you'll probably want to run godot from shell and paste/attach the entire output from the shell.
duane this GitHub issue explains it pretty well: https://github.com/godotengine/godot/issues/81613
I just can’t fix it 
Did you try what the original poster did? Uninstall everything (including unity) and reinstall just jdk, android, and godot?
As a workaround, you could boot up a linux live-drive and export from the linux version of godot. I'm not having any problems with custom builds. Unfortunately, you'd have to download the android sdk files for linux before attempting it. On the other hand, if the problem is the libraries you're putting into your custom build, this won't help at all.
duane Ok so the only thing I didn't do is reinstall godot. And guess what. After installing it again it worked!
Re install godot?
belgian_street_lamp help me solve this bro been trying to fix this for the last 7 days
reduzio hmm i also completely reinstalled openJDK. I deleted the old folder and then installed it again. Note that I didn't need to reinstall android studio at all. And if you want to feel better I can tell you that now im stuck on the next step (and you also will, probably) - opening the imported game on android crashes after boot screen. And the best part is I need to hurry because I need to update my game before October, or they will delete my game out of play store or something 
please help
