This is not surprising that Google is encouraging developers developing Android applications to use the latest API versions. In November last year, the company ordered everyone to upgrade their programs so that they were also focused on the Android 8.0 Oreo operating system. Now this requirement will increase.
From August this year (possibly since the premiere of Android Q) all new applications that will appear in the Play Store will have to be compatible with the API at level 28, which is targeted at Android 9 Pie. It is not about the fact that only this version of the system will start to be supported – developers can provide support even for Android 1, but they must also think about the latest version of the software.
From November, this requirement will also include updates provided by all application developers. Non-upgraded services will not be covered by this requirement. Interestingly, Google Play Protect will soon warn users when they decide to download applications that are not compatible with Android Oreo, the level of API at level 26.
