title: How to rerun a debugging version of an app on a device without reuploading from Android Studio?
body: <p>I am following the guide <a href="https://developer.android.com/training/basics/firstapp/" rel="nofollow noreferrer">Build your first app</a> at <a href="https://developer.android.com/" rel="nofollow noreferrer">developer.android.com</a> to get started with development. I am using a laptop with Ubuntu 18.04 and Android Studio 3.1.2 for development. At the end of the tutorial I clicked the <code>Run</code> button and I was able to upload and install the app on my device
   (Moto G, Android version 7) using an USB cable from my laptop. The app seems to run fine on my mobile device, but when I click the back button in the app it exits and I am not able to rerun the app (I cannot find any Icon for it on the home screen on my device). </p>
  
  <p>Of course, I could upload it again from Android Studio, but I would like to keep it on the device, such that I can rerun it without being connected to Android Studio via the USB cable. What is the easiest way to achieve this?</p>
