Known Issue: Due to Google Play Developer Distribution Agreement, we can't dynamic update our apk.
Presumably to 'stop' a clean app morphing into malware?
I've not looked closely but I think 'without the user having to restart the app' should be 'without having to reinstall the apk' so in other words, taking app updates out of googles and optionally the users control?
Having an app able to update its running code over the air seems like a very bad idea to me. Probably why it's targeted at developers who hopefully remember to remove it from releases..
