IllegalArgumentException: the bind value at index 1 is null
The bind value apparently refers to the selectionArgs for the selection, that you insert into query(). If such a selectionArgs value is null, you get this.
@Gray and @pjv response was the point for realize what problem caused this error. You have to be careful with selection and selectionArgs matching, if you pass selection = null and selectionArgs = something, you will get this error too! :) Thnks!
This does not exactly relate to the question, but I was facing a similiar issue for me the argument containted a dash (-) at the beginning. This was causing the issue.
So I escaped the argument like this
return mDatabase.query(table_name, null, column_name + "=?", new String[]{"\\" + argument}, null, null, null);This solved it for me.
