SOLVED : THE FIX WAS TO HAVE A TARGET LEVEL API OF 29

So recently I made an app in unity using Firebase Database, Auth and Storage. Everything works fine in the editor and when using remote player. But when I try to build it to android, I get some errors"

Those are the errors, i have tried creating a new keystore but nothing and the password is correct. I cannot seem to solve it. Thanks

It says you have

android:requestLegacyExternalStorage

in your manifest file, and it’s not being found

3

Hi, thanks for the help, can you please tell me some work arounds? Thanks

4

Google says you need to target API Level 29 or higher, alternatively remove android:requestLegacyExternalStorage from Android manifest, something’s in your project is adding it.

5

Thanks, if I target level 29, am I still able to run it on Android 9?

6

Yes, assuming you keep Min Target API below 28, it’s recommend the keep this value as low as possible, that way you’ll support the biggest range of Android OS’es, supported by Unity.

Yeah, the fix was to set the target api level to 29.
