You can simply put JSON on one String and send it using the method putExtras() in this way:

Intent intent = new Intent(this, DestinoActivity.class);
intent.putExtra("json", jsonobj.toString());
startActivity(intent);

To rescue again the String in Activity, just insert you to JSONObject using the method getStringExtra(). See how it would look on your onCreate():

public class DestinoActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_destino);

        Bundle args = new Bundle();
        JSONObject obj = new JSONObject(args.getStringExtra("json"));

    }
}

For more details about the Intent, see in the documentation.
