Consider adding Android app developer compatibility and best practice guide

[stevendkwtz]

Forgive me if this is available somewhere and I've missed it.

Consider adding a prominent "android app development compatibility & best practices" section to the website.

Independent android developers may unintentionally limit GrapheneOS compatibility in various ways (such as when switching over to Play Integrity API). It would be great to provide a development guide with clear instructions for ensuring compatibility, and solutions for remediating existing incompatibilities.

Additionally, this may be a great place to offer opinionated best practices for android development in general.

• How and where developers can publish apps (e.g. F-Droid, GitHub, Google Play Store)
• Best practices for respecting user privacy & security (e.g. "App monetization options, offer license key for paid version on ProxyStore")
• Ways to implement common app behaviors without requesting unnecessary permissions
• etc

We already cover attestation and there isn't really anything else specific to GrapheneOS. We're not going to be making generic guides for app developers.
