Qt5 on android arm64?
-
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.
