If you install the sandbox plugin in ICS and it is nos listed in the plugins list and in the Clock you should add an action (see red action in next code) into the intent-filter of your Android Plugin Manifest:

Your intent filter of the plugin service must look like:

<pre style="background-color: #f0f0f0; background-position: initial initial; background-repeat: initial initial; border: 1px dashed rgb(204, 204, 204); font-family: arial; font-size: 12px; height: auto; line-height: 20px; overflow: auto; padding: 0px; text-align: left; width: 99%;"><intent-filter>
<action android:name="com.sonyericsson.extras.liveview.plugins.sandbox.sandboxpluginservice" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</pre>
