Hi @PLloyd and welcome to the forum!

Could you share the exact wording of the “Android SDK is not valid” popup? A screenshot would be great too.

There’s a similar issue discussed here:

> [@Android Mode crashing on my Linux](https://discourse.processing.org/t/android-mode-crashing-on-my-linux/47953/):
>
> I get this “Nasty Error” dialog: Processing 4.5.2 Android Mode for Processing 4 v4.6.1 I tried to re-install everything, but it didn’t help. Any suggestions?

Could you take a look and let us know if your error matches that one? That’ll help figure out whether it’s the same problem or something different.

Also could you tell us what operating system you’re using? Windows, Linux, macOS?
