When I run (both on the Android emulator on the PC and on the smartphone) the App returns the following error:
<p>Installation failed with message Invalid File: C:\Users\Rubinho\AndroidStudioProjects\Let&amp;amp;amp;apos;sFriend2\app\build\intermediates\split-apk\debug\slices\slice_8.apk.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.<p>
WARNING: Uninstalling will remove the application data!<p>
