now the saveFile method for android uses the fileName as input file from where it reads the content to be written in the file that the user is going to choose. this way there is no need to ask for permission and no need to delete the 0 byte file created by the save filePicker window. From the android app ONLY you need to write the file in a temporary file before calling the saveFile() method. then you pass the temp file to the saveMethod(), the user choose the file where the content of the temp file will be saved and the temp file is written to the file chosen by the user

I implemented a saveFile method for the android platform because I needed it.
I don't know if it is interesting, I think that you already know how to do it but maybe violates some android security rule and that's the reason why you didn't add it.
If this is the case just ignore it.
The only way I found to implement the method is by removing the file that the saveFile dialog creates because that file cannot be written by the calling thread. By removing the 0 length created file and returning the path, the calling thread is able to open the file, provided that the file is in an accessible folder.
