I don't understand anything anymore.
What are the recommended versions of Android NDK, Android SDK to use with Qt 5.15.1?How to fix Android compatibility warnings ? I have more than twenty but I don't understand anything... Am I using a bad version of SDK ?
Some examples of warnings

Hi,
The information you are looking for is in the Getting Started With Qt For Androïd chapter in Qt's documentation.

Thank you SGaist for this information. So we can use Qt 5.15.1 with SDK 29 and NDK r21d ?
But how to explain these warnings that tell me there is a compatibility problem with the SDK version (29) ?
-
If it's the latest and greatest from Google, then I would go with the previous version. Each new release of the NDK has a tendency to break something for external projects using it.

I have a problem selecting the correct version of ndk in qtcreator 4.13.1
I can select a version but it's always the version 21.1.6352462 that is finally used during the compilation...
How to solve this problem ?
