- NDK and native C/C++ app development; see android-ndk

- proprietary apps or features beyond AOSP

- high-level app development; see other resources such as Stack Overflow etc.

- bugs and feature requests; see Reporting Bugs

- empty, me too, class assignments without effort, non-technical, commercial, recruiting, lobbying, spam, flamebait, philosophical, etc.

- multiple posts of similar content; this is a moderated group so please wait for moderation rather than re-posting

- cross-posts; pick the one best group rather than posting to multiple groups; this includes re-posting of Stack Overflow questions

- inappropriate language or non-constructive criticism

- replies to inactive threads, or replies that introduce unrelated topics

- questions about release schedules and unannounced features
