When RAD Studio 10.3 Rio applications are executed on Android 9, you get an intermittent error due the call of a restricted API. As an example, this is reported at https://quality.embarcadero.com/browse/RSP-23008:
The issue is a call to a restricted platform API in FireMonkey, we are looking forward to remove in a future release.
There is a fairly simple workaround. The message is not displayed to the user (but only in the internal logcat) if you modify the TargetVersion parameter in the AndroidManifest XML file, setting it to TargetVersion = 28:
<uses-sdk android:minSdkVersion="%minSdkVersion%" android:targetSdkVersion="28" /
If you have an existing 10.3 Rio project for Android and you want to target Android 9 Pie, you should update the manifest file accordingly.
There is a workaround in the issue, just a change to the manifest suffices

It's very disappointing, that the refreshing problem for devices with older (5.1.1) Android versions remains unsolved. We are unable to develop any Androd Apps, not even updates.We are losing our customers, and I'm getting now the answer, that the ticket (RSP-23218) is planned to be solved in the next major release (Steve Axtell) in the second half of 2019! If Embarcadero makes fatal errors in Rio, it's to be solved ASAP. The Roadmap should be override. I cannot accepts an answer, that You don't have devices with Android 5. Buy one or we can send You.If we could, would ignore Rio, but the min. required SDK version of 26 let ius work with Rio, which seems to be the worst update since years.
... but when you use TMapView - this "fairly simple workaround" is useless
