Android API Demos 8 Translucent the class is TranslucentActivity.java doesn't do anything.

Question

TranslucentActivity.java doesn't do anything. There is no translucence, nothing special about it. It just shows an activity screen.

Answer 1

This is a question about what is wrong with the sample.

The very next sample, the Translucent Blur sample after this works, the prior screen is burred...

    // Have the system blur any windows behind this one.
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
            WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

And it shows what it claims to show.

But nothing is done in the TranslucentActivity, about which I am asking.

Answer 2

This must be just a holding class. See the Demonstration of the Wallpaper a few selections later which is identical ...EXCEPT there is no reference anywhere in the comments to the slight difference in the Manifest, which is how this all must be used.
