Gradle failed to link ofAndroidLib

A strange link error happened today when I tried to build the project from command-line, see the error below. This didn't happen when I used the make button in Android Studio.

./gradlew build

Add option to create console window in QtCreator wizards (#6105)

Start with the :openFrameworksProject:linkOpenFrameworksLibArmeabi-v7aDebugArm7SharedLibrary task and its output.txt log, then compare the command-line Gradle build with the Android Studio build. Trace how the reported Android symbols are included in the link; done means ./gradlew build completes without the undefined-reference errors.
