What does it say in the console when you try to build?

@DuckMint this didn't work? ⬇️

@DerekSP THANKYOU, I have waited so long for someone to tell me that XD

Ya download the SDK, go to Unity's compile settings, go to the Andriod tab, and fill the filepaths and then you can compile to Android, at least that's how it should work but for me it did not work either so good luck I guess

@Feanor Yeah everyone told me, "Use an SDK" That never helped, no-one actually knew anything after that

I can't exactly remember how I did it, but i do recall downloading and Android SDK, the SDK and saving it to andoid from SP mod builder
