Help Failed to find provider info for com.android.launcher2.settings

In determining whether there is a shortcut when the error : Failed to find provider info for com.android.launcher2.settings


Note: In the normal millet and simulator query shortcuts

This is my part of the code :
if (android.os.Build.VERSION.SDK_INT <8) {
AUTHORITY = "com.android.launcher.settings";
} else {
AUTHORITY = "com.android.launcher2.settings";
}

final Uri CONTENT_URI = Uri.parse ("content :/ /" + AUTHORITY
+ "/ favorites? notify = true");


Cursor c = cr.query (CONTENT_URI, null, null, null, null);
