an error occurred while deploying the file. install failed conflicting provider

Question

I generate apk file for my project but when I drag and drop it to genymotion I see this error:

an error occurred while deploying the file. install failed conflicting provider

Answer 1

I had same problem, solved it by uncheck Verify apps over USB under Developer settings

Answer 2

Actually @WenChao's answer is the solution, but for me this option was disabled. in this case you need to run following command (in order to uncheck Verify apps over USB option):

adb shell settings put global verifier_verify_adb_installs 0

Make sure adb is connected to emulator (run adb devices to see connected devices)

If you want to check the option (are you crazy?) just pass 1 instead of 0 in above command.
