    Has someone tried to build arm 64bit version of Qt5.5 for android ?
    Is it working?
    I built the source successfully, but got
    E/art (22196): No implementation found for void org.qtproject.qt5.android.QtNative.handleOrientationChanged(int, int) (tried Java_org_qtproject_qt5_android_QtNative_handleOrientationChanged and Java_org_qtproject_qt5_android_QtNative_handleOrientationChanged__II)

        So, how to disable neon ?
        There seems no -no-neon option.

          @Mr-Pang Why to disable neon?

          Do you have built qtimageformats submodule?

          If not go to qtimageformats folder in your Qt directory, run /path_to_your/qmake , then make and sudo make install.
