Ship a CometChat Android v6 app safely — server-minted auth tokens instead of the dev Auth Key, keeping credentials out of the APK, release-build and R8/ProGuard checks, user provisioning server-side, rate limits, and the Play Store publishing prerequisites. Triggers: 'is my cometchat android app production ready', 'auth token instead of auth key android', 'release build cometchat android', 'proguard cometchat', 'publish chat app play store'.
