There are a few poker apps for android nowadays. My OCR is not going that well so far, does anyone know if it's possible to somehow hook text functions on the emulator? Something like ExtTextout on windows?

I think you should use DirectShow to capture it.
Because standard С++ capture tools like

Code:

HWND hDesktopWnd = GetDesktopWindow();
HDC hDesktopDC = GetWindowDC(hDesktopWnd);
HDC hCaptureDC = CreateCompatibleDC(hDesktopDC);;
HBITMAP hCaptureBitmap = CreateCompatibleBitmap(hDesktopDC, nScreenWidth, nScreenHeight);
......

do not work with directshow propertly (and may be with openGL too).

Yes, that's what I am trying to do. I am not trying to create a screenshot from inside the emulator.

Basically I have my c++ application on my Windows desktop and try to screenshot the emulator window. I know how to get the s creenshot of the whole desktop, but the good thing about printwindow is, that you can pass it a HWND and it will even print background windows, but it's not working with any emulator so far.

Why not just take the screenshot from outside of the emulator or VM?

PrintWindow on Android emulator

2017-09-02T20:56:56+00:00

I have tried to take screenshots pf several Android emulators for my OCR, but so far it only returns a black image, or a completelly white image.
I have read, that the reason is probably, that they use OpenGL. I also tried to get the pixels from an injected DLL, with BitBlt and so on, but nothing is really working.
I can just screenshot the whole Desktop, that works but it sucks as the windows can not overlap.

Has anyone had success with screenshotting an Android Emulator?
