Having problems with Android Export

Godot Version

v4.4 custom

Question

So I just wanted to build an .apk with encryption, everything works fine on Windows. However I have 3 problems on android:

1- For some reason the APK just doesn’t get installed on android when I do not sign it, I am not going to release it to Google Play so why is this required?

2- The app doesn’t run in Android versions other than 14, I think this is because It only uses the 34 SDK API. But I can’t change that unless I use a gradle build.

3- The APK expansion doesn’t work, whenever I try and open the game it just crashes.

This is caused either because it asks some kind of Public key when I’m exporting(I just put in random text) that I’m supposed to get from Play Console, (But like I said I will not upload this on Google Play so I don’t have a dev account. Therefore there is no way for me to get that)
Also, when I checked my export templates’ binary, it doesn’t seem to contain my Encryption Key?? Yes I built it from source and yes I had the key set as an enviroment variable.

I just wanted to make a simple app to test the encryption and these happened,
any help is appreciated :frowning:
