Android上的PyQt5

Question

I was wondering if someone could explain to me how you make your PyQt5 application run on Android. The documentation is not very explicit regarding Android to say the least.

I am building on a Kubuntu desktop. I have Android NDK and SDK installed, I have Qt 5.5.1 for android.

I don't know how to proceed from here. I tried building PyQt5 for android like I would build it for Linux:

ANDROID_NDK_ROOT=<MY_NDK_INSTALLATION> python configure.py -q <PATH_TO_ANDROID_QMAKE>

but that just returns the following error:

Can anybody give a hint?

It would really be nice if someone could provide a guide to using PyQt5 on Android.

Answer 1

The code of qtdetail just generates a plain-text config so I ran its source on my Android-device and got this:

Open Source
shared
PyQt_Desktop_OpenGL

If you can not repeat my steps, you can apply this patch to configure.py (for Unix-like platforms)
