    1. You are getting FileNotFoundException error. It is because the file you are trying to open to write does not exists. Most likely, you have missed to create the file in your code. Please check if the below line is included before trying to access the file in your code:

      File myFile = new File(myFilePath);

      Also, check read and write permissions are declared in manifest file and checked by the user in the code before working with the files:


      If yes, then I will also recommend to check whether the file exists by using isExist API on file object. It will help in preventing the above exception from being thrown.
