How to save to file and read HashMap in ANDROID?

Question

Java

Good day to all!
How can I save the List<Map<String, String>> (written in Russian, otherwise it will not be displayed) to a file, and then read it from there?
Thanks in advance for your replies

Answer 1

Alternatively, you can simply write to a file:

File file = new File(*ваши данные*);    
ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream(file));
outputStream.writeObject( yourObject );
outputStream.flush();
outputStream.close();

You can also convect to JSON and also save to a text file (although in your case, the first method will be easier)
Then read the JSON from the file and parse it into a List<>

Answer 2

If the file is not large, then you can throw it into shared shares, as they wrote above, overtake it in json.
