I am developing an application related to home automation in android.

Suppose the name of my application is X and is installed on two different android Devices(user1 & user2)

I want to share the data(key value pair) of app X from user1 to the same app in user2

I dont want to use internet.

can we do it with sharedpreferences or bluetooth??

but data should transfer from app to app.

How to achieve this???

You can do this by sending a JSON object, through Bluetooth. After recieving the value from the other end, you can parse the JSON.

  • I cant use JSON that's the main problem. – Pranita Nov 03 '17 at 05:58
  • JSONObject student1 = new JSONObject(); try { student1.put("id", "3"); student1.put("name", "NAME OF STUDENT"); student1.put("year", "3rd"); student1.put("curriculum", "Arts"); student1.put("birthday", "5/5/1993"); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } – Souvik Brahma Nov 03 '17 at 06:01
  • Now you can send the json student1 to your other device, and parese the content – Souvik Brahma Nov 03 '17 at 06:02
