Hi agraham

I sent you some beer money via Paypal for your excellent libraries. I wonder if you could answer my previous question about the ParseUser object.

Thanks from the Squid!

First of all thanks that to write this useful lib and make it public.
I want change or extend the GCM service of google with the Parse Push service.
GCM referenced to a service not activity. Is the notification in the status bar the reason for the activity?

From the demonstration application is I exchange the activity Notification and want use my one one.
For the first step I just renamed the activity to >>MyOne<<.
After renaming I receive an error message

"Module Notification not found"

Seems the activity name notification is "hard coded".
The subscribe method and the methods for enable and disable notification comes with an parameter.
I guess this parameter might reference to the class shall be called in case a push message arrived.

Now there are questions:

1) The notification in the status bar is a must with this library? I need to receive the Information send by the push service in the background and in a silent way. My application checks the received data and decide what to do.
2) The parameter of the method subscribe reference and for disable and enable the notification the same. Is it a must for this wrapper library and what use are these parameters?
3) Does the Parse.com push service make use of any Google services comes with the Playstore similar Google push service?
4) To subscribe the push service, is it a must to reference to an activity? Can it be a service also? At least the required type is class. I cannot give a try because receiving a push message the activity Notification is called and not myone. What I've done wrong?

thanks for some answers and help

Edit: Sorry Sorry Sorry - found the problem, I forgot to enable push notifications in Parse.com
Now read the rest...because it works and it is not in the example.


Hi
There is a ParsePush object in the library which should send push notifications from the application.
I wrote the following definitions:

B4X:

 If FirstTime Then
      Parse.SetLoggingLevel(2) ' Verbose logging for testing only - remove for a real application
      Parse.TrackOpening  
      Parse.EnableNotifications(Notification)
      Parse.Subscribe("Channel1", Notification)
      GPS.Initialize("GPS")
      pofix.Initialize("Location")
     
      push.Initialize
      push.SetChannel("Channel1")
      push.SetMessage(name & " Updated Location")
  End If

and later there is

B4X:

push.Send("push",2)

This is in according to what the tutorial instruct:


The push is reported as success in Sub push_DoneSend but the PN is not recieved by the application.
In the Parse.com I have the attached report on push notifications, while the problem is that it was sent to 0 subscribers.
I thought maybe it sends to all but the initializing app, so I checked with two devices, but no.
What is wrong ?

send push notification from one android device to another one

what I do in my applications with parse is send notifications triggered by one user to all the users (example - update of an item in family tree).
I haven't sent from one device to only one other device, but it is possible - you have to know the user ID in parse.

Here are some subs with the code relevant to push notification. You have also to enable push in your prject in parse site.
There is no master -slave relations, any device that sends a notification broadcasts it to all.

B4X:

Sub Process_Globals

Dim Parse As Parse
Dim push As ParsePush

End Sub

Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("family.bal")

'parse
If FirstTime Then
    Parse.SetLoggingLevel(2147483647)
    Parse.EnableNotifications(FamilyNotification)
    Parse.Subscribe("Family", FamilyNotification)

    push.Initialize
    push.SetChannel("Family")
    push.SetExpirationTimeInterval(300)
   End If

End Sub

Sub delete_click
    push.SetMessage(Ft.Name & " " & Ft.Surname & " deleted")
    push.Send("push",2)
End Sub

Sub parse_add_item(k As Int)
Dim Addpo As ParseObject
Addpo.Initialize("Family")
p_item_common(k , Addpo)
End Sub

Sub p_item_common(k As Int, Npo As ParseObject)
...
    push.SetMessage(cur.GetString("Name") & " " & cur.GetString("Surname") & " updated")
...
push.Send("push",2)
...
End Sub

In manifest file I have this addes:

B4X:

SetManifestAttribute("android:installLocation", "auto")
SetActivityAttribute(FamilyNotification, android:noHistory, "true")
SetActivityAttribute(Main, android:screenOrientation, "landscape")
SetActivityAttribute(FamilyNotification, android:screenOrientation, "unspecified")

SetApplicationAttribute(android:name,"anywheresoftware.b4a.objects.ParseObjectWrapper$ParseApplication")

AddApplicationText(<service android:name="com.parse.PushService" />
<receiver android:name="com.parse.ParseBroadcastReceiver">
  <intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
    <action android:name="android.intent.action.USER_PRESENT" />
  </intent-filter>
</receiver>)

The way the notification is recieved is not controlled by the application or by parse, its the way android works. Can it be changed ? I don't know.

• alert: the notification's message.
• action:(Android only) the Intent should be fired when the push is received. If no title or alert values are specified, the Intent will be fired but no notification will appear to the user.

I am attempting to get the parse example up and running with the new parse1.7.0
The example compiles, installs on my device (nexus 7) but "stops working" before opening.
From the parse.com website I gather that 1.7.0 is pretty new. I wonder if anyone else is running this version of the with success?
Or Can anyone link me to an older version of the parse sdk that will work?
Thanks,
Quentin
