Qt for Android tools could use logging revamp to have a more meaningful description for errors/warnings and potential reasons to help the users figure out what's wrong with their builds. For example, the following error message is sent if the app's lib is not found in the android-build folder, this could be because ANDROID_ABIS is set to some abi that that Qt installation doesn't support/have.

Cannot find application binary in build dir C:/qtbug81687/android-build//libs/arm64-v8a/libqtbug81687_arm64-v8a.so.

Then androiddeployqt could additionally check the values of that variable and send a relevant error message.
