>> Wrong, use of adb backup feature or Helium app by ClockWorkMod (which re-uses adb backuo android code) does NOT require Google as backup agent. You need ONLY allowedBackup flag set as true. Believe me, I hacked this stuff via Xposed
Would it cause anything bad to happen with respect to Google Play backup?
Like, error messages, failures?
I have Play backup turned off on all my phones / tablets, so if you know the answer, please share.
>> Since Android M, every app will be backed up to Google servers, even sensitive info
Wonder if they'll be changing the developer agreement.
Many apps store user logins and passwords (but it's not an excuse to violate the current policy, as far as I'm concerned).
