I have a routine like this...
void SetNativeWindowHandle( ANativeWindow *displayWindow )
{
_32 new_w, new_h;
_32 real_h;
//lprintf( "Setting native window handle... (shouldn't this do
something else?)" );
l.displayWindow = displayWindow;
new_w = ANativeWindow_getWidth( l.displayWindow);
new_h = (real_h = ANativeWindow_getHeight( l.displayWindow) )
}
It gets called from with engine.app->pendingWindow
works pretty good.
The only problem I found with the functions is if you use a very old
SDK target you will get false numbers... but then android is auto
scaling for you... so your surface is reallly that width and height to
the app view and it's auto scaled to the correct resolution.
