Test the app on an Android P emulator

Android P is shaped by our longer-term initiatives to modernize the foundations of Android and the apps that run on it. As we announced recently, Google Play will require all app updates to target Android Oreo (targetSdkVersion 26 or higher) by November 2018, with support for 64-bit hardware on the horizon for 2019.

In line with these changes, Android P will warn users with a dialog when they install an app that targets a platform earlier than Android 4.2 (targetSdkVersion less than 17), and future platform versions will continue to increment that lower bound. We're encouraging every Android developer to start planning the migration to target API 26 now, and to start the migration work as soon as possible. Here's a checklist of resources for help and support -- we're looking forward to seeing your apps getting the most from modern Android.

Based on the above, I think we're OK for now, as our targetSdkVersion is 19, but may be forced to upgrade the application in a later Android release if we don't want users to see a warning dialog when they download the app.
