I was just finishing updating my 3rdParty libraries to ndk r26b when I noticed my android cmake strategy is not recommended any more. (which is of course my problem not yours)

The google docs state: https://developer.android.com/ndk/guides/cmake

• Warning: We do not recommend using -DANDROID_USE_LEGACY_TOOLCHAIN_FILE=OFF. The legacy toolchain is the default, and despite the name, is what we recommend.

What could be considered your "problem" is by default cmake android projects in QtCreator are configured with DANDROID_USE_LEGACY_TOOLCHAIN_FILE=OFF. This may also have consequences for the deployment of your android binaries.

I just wanted to ask if you are aware of that, for me it was a surprise.
