What client are you using on Android? You mostly don't need Zeus anymore.

Most have a quick button press setup.

In Amethyst you press and hold the lighting bolt on any note and you'll get a zap setup page like this-

#m=image%2Fwebp&dim=1080x2340&blurhash=%5BH7wU2WmNEax%3F1WANEj%5Bs%3Fo3R%24fSR%23ogogoMIkjcxcofIka_%24-axEIWAxcWUNDWUoMayR%24jvR%24of&x=f5105e48a6573f3d2f06d78dc59dff436fc73128a0475db9f53fb0705c1462d2

And you just need to press the little Alby logo and it will take you to a webpage to enter your Alby account login and approve the setup. The it should send you back to your nostr client with all the setup info filled in and you just need to save.
