Session 'app': Error Installing APK

Question

Trying to install app on real device following instructions:- http://developer.android.com/tools/device.html. At end Android Studio giving error:

Session \'a         


        

Answer 1

I fix this by delete the build folder then run project again

Answer 2

I changed my USB port and that fixed it for me.

Answer 3

It was written above: in my case it was just out of memory on device storage. Add more empty space - and error will disappear

Answer 4

My problem was that I didn't accept the connection from the computer after turning on remote debugging. Once I accept the mac address, it went away. Silly mistake, but I didn't see the dialog box the first time. Worth a quick check if the others don't resolve the issue. But likely only a problem the first time you set up a phone.

Answer 5

Try to remove the .idea folder and .gradle folder, then click Sync Project with Gradle Files, when the process finished, try to run app again.

Hope it works.

Answer 6

Usage of easily changing variable value will often happen in build.gradle(like the Date)
