my code was ok and I tested it several times and it works until an xml mismatched parsing error appears and I cannot find the error. After I add the image, when trying to build the following error appears: Several annotations found on this line: - error: XML parsing: tag mismatch - The type of the element "LinearLayout" must be completed with the corresponding end tag "". Does anyone know what is wrong with my code? thank
