Running App From Android Studio Does Not Save Onto My Android Device Anymore

I have only just started android programming, but I have a few basics programs working. Normally when I click run in Android Studio and choose my galaxy nexus as a running device,

Solution 1:

Make sure that "deploy the APK" is selected in Run-> Edit Configurations

Solution 2:

You have to set it at the new project screen. Its greyed out but theres a link next to it. Just click it. Its next to the Package name and that is the only .app extension you need to execute the apk.

Solution 3:

I had the same issue. For me the problem was that the icon was not appearing on the screen but I found the app was actually stored on the device. I have installed NovaLauncher on a Meizu U20. I went to see the "Applications List" (tr. it. "Menu delle app"), I found my app icon there and I drag/dropped it on the screen.
