这个问题通常发生在使用ContentResolver进行查询时，查询的参数中包含了非法字符。为了解决这个问题，需要对查询参数进行检查并去除非法字符。

以下是示例代码：

Dim projection() As String = Array As String("_id", "name", "phone")
Dim selection As String = "name LIKE ?"
Dim selectionArgs() As String = Array As String("John%", ";DROP TABLE contacts")
Dim sortOrder As String = "name ASC"
Try
   Dim cr As ContentResolver
   Dim uri As Uri
   Dim cur As Cursor
   cr = getContentResolver()
   uri = ContactsContract.Contacts.CONTENT_URI
   cur = cr.query(uri, projection, selection, selectionArgs, sortOrder)
   ' do something with the cursor
Finally
   If cur.IsInitialized Then cur.Close
End Try

在上面的代码示例中，我们使用了一个包含非法字符（";DROP TABLE contacts"）的查询参数，这会导致ContentResolver错误。要解决这个问题，我们需要对selectionArgs参数进行过滤，去除掉非法字符，例如：

Dim selectionArgs() As String = Array As String("John%")
For i = 0 To selectionArgs.Length - 1
   selectionArgs(i) = selectionArgs(i).Replace(";", "").Replace("--", "")
Next

通过这样的方式，我们可以避免在查询参数中包含非法字符，进而避免ContentResolver错误。
