Hello,
I recently uploaded a document that details our plans to refactor some of the 'classic' emulator code base to make it reusable with the QEMU2 one (under external/qemu-android/).
Until now, we've slowly rewrote missing features from scratch, but this approach is not scalable, hence this new proposal. Feel free to comment directly on the following page:
