Question

In the Android SampleSyncAdapter there is the following piece of code:

/**
 * Adds a profile action
 *
 * @param userId the userId of the sample SyncAdapter user object
 * @return instance of ContactOperations
 */
public ContactOperations addProfileAction(long userId) {
    mValues.clear();
    if (userId != 0) {
        mValues.put(SampleSyncAdapterColumns.DATA_PID, userId);
        mValues.put(SampleSyncAdapterColumns.DATA_SUMMARY, mContext
            .getString(R.string.syncadapter_profile_action));
        mValues.put(SampleSyncAdapterColumns.DATA_DETAIL, mContext
            .getString(R.string.view_profile));
        mValues.put(Data.MIMETYPE, SampleSyncAdapterColumns.MIME_PROFILE);
        addInsertOp();
    }
    return this;
}

I added this as filter for my activity

    <intent-filter>
        <action android:name="@string/syncadapter_profile_action" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="vnd.android.cursor.item/vnd.myapp.profile"
            android:host="contacts" />
     </intent-filter>  

where SampleSyncAdapterColumns.MIME_PROFILE = vnd.android.cursor.item/vnd.myapp.profile

I added a contact and I can see the entry but when I click on it nothing happens. What should I do to start an activity when the user clicks on it?
I was trying to do what is suggested Here for Pre-honeycomb devices: The trick is to insert a data row, “Edit in MyApp”, which would take the user to your app and your app
would then provide an editor activity

I think your intent filter might be incorrect. According to this entry, the correct action and data items should be something like the following:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="vnd.android.cursor.item/vnd.myapp.profile" />
</intent-filter>
