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

Shortcuts in judging whether an error exists when: Failed to find provider info for com.android.launcher2.settings


Note: In the normal query millet and simulator shortcuts

This is part of my 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);
