Android users frequently use the back button on the lower panel of the Android interface to perform a back operation and return to previously viewed screens
By default, with a canvas app, this button invokes the Android prompt to close the app. Clicking ‘Close’ will result in any data that isn’t saved being lost
There is an experimental feature that allows the Android back button to be activated so it operates in the way Android users are familiar with
Two steps are required to activate this
Step 1: Open the settings for the app and under Experimental features, turn on Android back button
Step 2: Within Power Apps Studio, select the App.BackEnabled property and change to ‘true’
Publish the changes and open the app in an Android device
Click through several screens and now you’ll find that using the Android back button works as expected and you can navigate back to previous screens
