Android searchmanager triggersearch giving null pointer exception

Here is the code getting searchmanagerinstance and calling trigger search: The same works fine with startsearch call not with triggersearch

String searchQuery = "dollar in rupees\n";
SearchManager s = (SearchManager) this.getSystemService(Context.SEARCH_SERVICE);
// s.startSearch(searchQuery, false , null, null, true);
s.triggerSearch(searchQuery, new ComponentName(getApplicationContext().getPackageName(), "MainAcitivity" ), null);

This is the error i get when this code is executed:

07-17 12:17:04.650: E/AndroidRuntime(1265): java.lang.IllegalStateException: Could not execute method of the activity

When using ComponentName you need to use the full path. I'll demonstrate with Strings below:

new ComponentName("com.example.package", "com.example.package.MainActivity");

You cannot just declare the Activity/Class name alone in the second parameter. At least not in the way in which your code shows.

EDIT: Regardless of the above, there is a bug logged in the issue track here

EDIT: Even using reflection to get around the null field, I can't get this to work

Field field = searchManager.getClass().getDeclaredField("mAssociatedPackage");
field.setAccessible(true);
field.set(searchManager, "some String value here");
Object value = field.get(searchManager);
// Check value here
