If they were serious
Fix REGULAR Android Apps FIRST!
1) No in App "reporting" to Google, other 3rd parties or seller
2) No in App adverts
3) Proper disclosure of App permissions, what they are for and reporting etc in the Playstore.
4) Proper disclosure of in App purchases (An upgrade to a different version is not the same as game add-ins).
5) Ability to turn off permissions per object, even if installed on older Androids such as 4.x etc.
6) info in Playstore if printing, screencasting, external storage etc is supported.
The user has too little information in advance of purchase and too little information afterwards.
Why so few Apps support printing and external storage? 1992 Windows and its applications were better thought out than the Android + Apps mess.
