After quite a bit of 4kery i managed to build a
subsurface-android-x86_64.apk and test it in a android 5.0 (api 21)
emulator and here's where it crashed:
E/AndroidRuntime( 3525): FATAL EXCEPTION: qtMainLoopThread

On android-28, it expoded a bit differently:
09-27 15:02:59.288  4776  4776 W edivelog.mobil: Accessing hidden field Landroid/graphics/NinePatch;->mNativeChunk:J (light greylist, reflection)
09-27 15:02:59.288  4776  4776 E edivelog.mobil: No implementation found for int[] org.qtproject.qt5.android.ExtractStyle.extractNativeChunkInfo20(long) (tried Java_org_qt
project_qt5_android_ExtractStyle_extractNativeChunkInfo20 and Java_org_qtproject_qt5_android_ExtractStyle_extractNativeChunkInfo20__J)


Whats the take away? Don't know. Either I can't build subsurface-mobile
for x86_64 or somethings broken.
