Compare your code with this (dont look at the content as it is different. But it is using TWO parameters!
AddActivityText(Main,
<!-- Activity that allows the user to send new SMS/MMS messages -->
<activity android:name=".ComposeSmsActivity" >
<intent-filter>
<action android:name="android.intent.action.SEND" />
<action android:name="android.intent.action.SENDTO" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="sms" />
<data android:scheme="smsto" />
<data android:scheme="mms" />
<data android:scheme="mmsto" />
</intent-filter>
</activity>)
The code I wrote is straight from facebook's directions, so I would not know what to add etc. Again, that is facebook's example for developers to use.
In your code, I can't tell what the 2 parameters are, is it the
<action android:name line,
<category android:name, or both distinct lines that make up the "2" parameters? And again, I would not know what to enter because the facebook example does not include any extra lines.
