I noticed that you have assigned app as Required to all devices, is there any errors in the Managed Apps pane. You should be able to view installation issues, such as when the app was created, modified, targeted, and delivered to a device.
Also, note that for the Intune service to successfully deploy a new APK file to the device, you must increment the android:versionCode string in the AndroidManifest.xml file in your APK package.
