Android: SQLite query with selection WHERE clause is not processed

Ok, so it seems query() method of your provider is causing problems.Make sure it looks like following.

@Overridepublic abstract Cursor query (Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {...// run the querydb.query(db, projection, selection, selectionArgs, groupBy, having, sortOrder, limit);

You are not forced to use selectionArgs parameter, but with it code is more readable.To debug a query you can use

SQLiteQueryBuilder qb = new SQLiteQueryBuilder();Log.e(TAG, qb.buildQuery(projection, selection, selectionArgs, groupBy, having, sortOrder, limit);

EDIT:If you have a ContentProvider implemented you don't need to expose getLocations() method as you/users can use ContentProvider's query() method.You should pass at least those arguments whose can be passed in query() method and those are projection, selection, selectionArgs and sortOrder.

Shouldn't that line be:

Cursor cursor = getContentResolver().query(uri, null, getSelectionString(), null, null); 

Note the added parens after getSelectionString to indicate it's a method call, not a string (although I do wonder why that wouldn't throw an error as getSelectionString wouldn't exist as a string if my theory is correct...).
