如何使Android Home Launcher具有透明背景（不是不透明）

Question

I'll trying to developing the home launcher with transparent background. So, the view of previous executing app go to the background of home launcher, and it is continuously running. In other words, without stopping the previous app, while still running a app, the home launcher with transparent background is running on it.

Can i make a this feature by using just Android SDK? If it need a modify to the Android Framework, please, advise to me how to modify and which source code.

I don't think this is a good idea. First, system transparent color on same devices can be not transparent. It can be same color, or image.

You can take screenshot before show you activity.
