Hide activity

Each activity has an <activity> node. You should add the theme as an attribute to this node.

<activity android:theme="@android:style/Theme.Translucent" android:windowSoftInputMode="stateHidden" android:launchMode="singleTop" android:name=".main" android:label="Smiley" android:screenOrientation="unspecified"> <intent-filter>...

Make sure to set AndroidManifest.xml to be read only. Otherwise it will be overwritten when you compile.

Ok, sorry for late answer.

I've been playing with this a bit today, I wanted a full screen translucent activity so that the background could be visible behind parts of the activity that didn't have my panels on it.

Unfortunately this only works correctly for Android 2.3 and up. For 2.2 and below the activity is translucent and full screen, but the notification bar is overlaid on top. Searching Google I found no solution, just frustrated programmers.
