For this question, how to disable google asking regularly checking app, there are answers like "uncheck the option Settings > Security > Verify apps". However, on Lollipop I am using, there is no such an option, instead there is an option "Unknown sources".
I unchecked this "Unknown sources", and I could have my app installed. I was asked if "google can regularly check installed apps for potentially harmful behavior". I clicked allow (by mistake). Then I can not start my application. Every time I click my app to start it, it is going to run, but immediately, it is stopped by google.
Do you know where can I configure the android to allow my app to run?
Thanks a lot in advance!
