Android: How to save a JSON file that let you keep the data even after power off?

Okay, so I have this file system using serializer to save an arraylist into a JSON file. The JSON file is created in the code. If I turn off the power, the data and file is erased. So if I want the data saved and reloaded even when the android phone is restarted. Which way to save data is the best? Can we use a JSON file to do that?

You can use SharedPreferences or saving it to external storage orsaving it to SQLliteDB

you can convert the JSONObject to a string and save by using one of the above methods.

for examples on using different storage options please refer Storage options

You can save in a file into the sdcard or you can use the SharedPreferences. In fact the toString() of a JSONObject returns a String that represent the json itself
