User Manual
Qt will by default use the GNU libstdc++ library which is distributed as part of the Google Android 
NDK. Qt Creator will copy this library into the .APK for any Qt-based Android app. The library will 
then be loaded by the app on start-up to meet the run-time requirements of Qt.
The GNU C++ run-time is licensed under the GNU General Public License version 3 with an 
exception which grants permission for run-time linking and usage of the library by an application 
which would otherwise violate the terms of the main license. For more information about this 
exception, see the official license page.
