How do you install an apk on the emulator in Android Studio from the terminal?
In Eclipse we did
/home/pcname/android-sdks/platform-tools/adb -s em
Drag and drop apk if the emulator is launched from Android Studio. If the emulator is started from command line, drag and drop doesn't work, but @Tarek K. Ajaj instructions (above) work.
Note: Installed app won't automatically appear on the home screen, it is in the apps container - the dotted grid icon. It can be dragged from there to the home screen.
