Android Install APK
You can install an APK using the standard development steps with adb, or you can do this entirely without the USB OTG connector. From the stock Android go to the application menu at the bottom and open the Settings application.
Go to security and check "Unknown sources" and press OK.
Go back to settings and open the browser. Enter in the browser the address for the APK.
Once downloaded, swipe down on the notification tray at the top and click on it. It will ask you if you want to install the apk with any listed permissions. Click install and you can run your application.
