INSTALL_FAILED_MEDIA_UNAVAILABLE - Android Build

Recently, I have been getting the following error
in the console on building my game directly to
an android.

Installation failed with the following output:
pkg: /data/local/tmp/Package.apk
Failure [INSTALL_FAILED_MEDIA_UNAVAILABLE]
3151 KB/s (16731030 bytes in 5.185s)
UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

And the also shows “Error building Player: UnityException: Unable to install APK!”

Any Idea how to fix this problem ?

same problem here looks like a Unity 4.2 issue!! :frowning:

I had the same issue and removing some other apps from the phone fixed it. Apparently it had run out of space.
