title: Android Studio: App in emulator not showing updated code
body: <p>So in my Android Studio Project, when I click "Run" for the first time, the app gets deployed to the emulator after a few minutes. Then when I change my code and click "Run" again, the app loads on the emulator (within seconds) but it doesn't show anything I updated. </p>
  
  <p>So what I basically have to do is uninstall the app on the emulator and click on "run" again. It works but the problem with this is that it takes 4-5 minutes to deploy the app to emulator. It says "gradle build running" and it finishes after 4-5 minutes and I can't wait that long every time I change my code. So how can I make it so that when I click "run", it shows updated code so I don't have to keep uninstalling the app.</p>
