Why does FunFact Android app reset itself on an actual phone?

I just completed the Testing and Debugging stage of the Build a Simple Android App course. In the last part of that section the presenter talks about running your app on an actual phone. My phone is a Google Nexus 5 running Lollipop. I was able to connect the phone and the app runs on it as described in the video. I have noticed that whenever I rotate the phone the app restarts itself. What would cause this to happen?

I have been testing on a different phone but I have not noticed this problem. This would be a great chance for you to do some troubleshooting on your app. I have searched google and found this StackOverflow question which might help.

The accepted answer has three solutions. I would use the third one myself because it seems simple and straighforward.

The solution Ben Hollands suggests is the second on the accepted answer and a great alternative.

The link was very helpful. I found an answer further down the page, one of the non-accepted answers, which did the trick for me. The answer from Josue Rocha advised adding a line to the XML in AndroidManifest.xml.

android:configChanges="orientation|screenSize"

Doing this worked for me.

Hello i had the same problem , i think this is just a rendering problem because the app was originally made for Portrait? Maybe you can fix the orientation in the Android Manifest file with?

android:screenOrientation="portrait"

It works, thanks. But I'd like to learn how to enable rotation for my app, of course without restart the app.
