How to darken a screen in android?
<p>Say I have a menu sliding out in android and I want to darken whatever was behind it.</p>

<p>I tied making a full screen layout and use a countdown timer to make its background gradually go from transparent to 50% black, but it gets slow as hell.</p>

<p>Are there any other options to make a gradual transition? Other then making it in a snap?</p>

<p>Thanks!</p>
