Xamarin support will end on May 1, 2024, it's recommended that you migrate your Xamarin app to .NET MAUI. Please see Xamarin official support policy .

Could you share your error when you read and write files in internal storage on android 13?

Which type of file do you want to read and write file?

For example, if you want to read/write characters in the text file. We store the text file in the Xamarin.Essentials: File System Helpers , you can refer to the following code.

var mainDir = FileSystem.AppDataDirectory; string fileName = Path.Combine(mainDir, "temp.txt"); //write text to the internal file File.WriteAllText(fileName, "this is test text"); //read text to the internal file. string text = File.ReadAllText(fileName);
