"Detected problems with API-compatibility"

Question

I am using the current Delphi 10.3 release along with the current TeeChart FMX 2018.26 release. The Android device is a onePlus 6T with Android 9. Unfortunately, a "detected problems with API-compatibility" is currently being shown. I have used a completely new project with only a simple chart of TeeChart, so I can rule out other incompatibilities.

Is there any usable solution for this?

Answer 1

Referencing to docs: In Android P, this dialog showing

Detected problems with API compatibility

Why this dialog is being shown?

Reason: Your code hit the

dark greylist

What are dark greylist apis? Such apis that are not permissible to call by other apps, In my case i was using the startSoftAp method that was dark grey listed. Removing that call vanished the dialog.

How will you find?

In your logcat -> verbose -> Search("Accessing hidden")

LOGCAT RESULT

Accessing hidden method:Landroid/net/wifi/WifiManager:startSoftAp(Landroid/net/wifi/WifiConfiguration;)Z (dark greylist, reflection)
