App Naming (Android)

Two names. One is irreversible.

Two names

1. App name (Play listing, 30 chars) — changeable anytime
2. Package name (com.yourcompany.appname) — IRREVERSIBLE

Once published with com.foo.bar, you cannot change it. Forever.

Package name rules

• Reverse domain pattern (com.yourcompany.appname)
• Lowercase, no spaces
• Don't use "android", "google" (trademark)
• Don't use "test", "tmp" (the user's first habit-app got published as com.example.app — STUCK)
• Avoid generic names that competitors can clone
