Retrieve info from JSON bundle [duplicate]

Question

While receiving a notification I am receiving some data mentioned below

Bundle[{google.sent_time=1233212221545, msg={"message":"You received a chat message","type":"Match Maker","request_id":"501"}, chat={"owner":0,"request_id":"501"}, from=148566781839, google.message_id=0:148354545211779676%c3fc9c6ff9fd7ecd, android.support.content.wakelockid=3, collapse_key=do_not_collapse}]

From this I want to retrieve

1. message
2. Request_id
3. Owner
4. type

I am trying to retrieve like this

String mes1 = extras.getString("chat");

I am getting these values

{"owner":0,"request_id":"501"}

Example: from the above I want to get owner and request id how to retrieve these values.

This is my code :

public class GCMIntentService extends IntentService {
    public static final int NOTIFICATION_ID = 1;
    private static final String TAG = "GcmIntentService";
    UserLocalStore userLocalStore;
    private NotificationManager mNotificationManager;

    public GCMIntentService() {
        super("GcmIntentService");
    }

    Intent notificationIntent;
    String type,token,requestid,notify_message;
    Context context;

    @Override
    protected void onHandleIntent(Intent intent) {

        userLocalStore = new UserLocalStore(this);
        Bundle extras = intent.getExtras();

        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);

        // The getMessageType() intent parameter must be the intent you received
        // in your BroadcastReceiver.
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
            /*
             * Filter messages based on message type. Since it is likely that GCM
             * will be extended in the future with new message types, just ignore
             * any message types you're not interested in, or that you don't
             * recognize.
             */

            if (GoogleCloudMessaging.
                    MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
                sendNotification("Send error: " + extras.toString());
            } else if (GoogleCloudMessaging.
                    MESSAGE_TYPE_DELETED.equals(messageType)) {
                sendNotification("Deleted messages on server: " +
                        extras.toString());
                // If it's a regular GCM message, do some work.
            } else if (GoogleCloudMessaging.
                    MESSAGE_TYPE_MESSAGE.equals(messageType)) {

                // Post notification of received message.
                Notifyvalue msgvalues = new Notifyvalue();
                Log.i(TAG, "Received: " + extras.toString());

               String mes1 = extras.getString("chat");

                type = extras.getString("type");
                notify_message = extras.getString("msg");
                Global.notification_type = type;

                if (authenticate() == true || userLocalStore.getFBLoggedInUser() == true) {
                    if(Global.notification_type.equals("Match Maker"))
                    {
                        notificationIntent = new Intent(this, Chatactivity.class);
                    }

        }

                 // Release the wake lock provided by the WakefulBroadcastReceiver.
                 GcmBroadcastReceiver.completeWakefulIntent(intent);
    }

Answer 1

After using that method you have received a JSON value so instead of getting in string you should use JSONObject like below :

JSONObject object = new JSONObject(extras.getString("chat"));
String str_owner = object.getString("owner");
String str_request_id = object.getString("request_id");

I hope you understand about JSON concept.
