On my Samsung Galaxy S4 with Android 4.4.2, I get constantly a dialog saying "Gmail has stopped" (In french, actually : "Gmail s'est arrêté"). When I click OK, the message re-opens within less than a second.
I tried to restart my device, to no avail. I still get the message.
Anyone knows a solution?
Edit: just an update on how things started: I wanted to kill a bunch of tasks and ran Advanced Task Killer. I probably left Gmail selected and so killed it with the tasks I wanted to get rid of. And all hell broke lose...
