From what I read on SO, it seems that I want the impossible (?)
I have a kiosk-like app that is supposed to run 24/24, 7/7, 365/365. This makes it hard/impossible to update the app. As far as I know, Google Play will not start the update (even if Autoupdate is set for my app) while my app is running.
I read across SO and several forums an found a lot of NO's and CON's. My current answer is that is not possible without rooting the device or without some system certificates and so on.
But still, I have the following scenario:
I created a google account myGoogleAccount@gmail.com
On my device I add this account and install my application from Google Play store.
On my desktop machine I log into GPlay with the same account and I go to my application and I see that my app is Installed. If I click on the Installed button I can see my device.
I publish a new version of the app, when the app becomes available, from my application's page open on desktop I can send a command to update the app. I get the prompt to accept the terms bla-bla, and once I accept it, the app is automatically updated even if it is currently running.
Basically this is the behavior I am interested in. My question is: can I run this scenario from my device [invoking some GPlay api's] given the fact that I can provide the google account credentials to the app, so that no user intervention is required to update the app and to accept whatever unchanged permissions?
