I met the same problem on ASUS ME176C(Lollipop 5.0),
but I resolved it by setting "Select debug app" to "No". Then push apk as usual. After that, you can reselect "debug app" to target app.

I'm not sure what the underlying cause is, but I found I could successfully avoid this issue by closing down all running apps on the phone before trying to Run my code on my M8.

Answer 4

On my HTC M8, I resolved the issue by disabling "Settings -> Developer options -> Use NuPlayer(experimental)"

Hope this helps....
