Push Notifications Not Being Delivered Via Custom API Services

Messaging Service Push Notifications
1

Hello Backendless,
I was Trying to Publish Messages through Push Notification Via Custom API Services. But It Gives me the Error as :

{
  "code": 0,
  "message": "Type:\"java.lang.NoSuchMethodError\", Description:\"com.backendless.Messaging.publish(Ljava/lang/String;Ljava/lang/Object;Lcom/backendless/messaging/PublishOptions;)Lcom/backendless/messaging/MessageStatus;\", ExceptionClass:\"ServiceException\"  {Msg:\"none\", Cause:\"none\"}"
}

I could achieve the Push Notification with Same Code Via Custom Business Logic , but It’s not working with the API Services
I don’t know why it’s behaving like that :
My Code For the Push Notification which is working perfectly in the Custom Business Logic is:

PublishOptions publishOptions = new PublishOptions();
//We are going to Recieve Some Sorts of HEader off here
//Just to make Things light on the Header part
publishOptions.putHeader( "android-ticker-text", "His Book Firfire is Awesome" );
publishOptions.putHeader( "android-content-title", "Buddhi Sagar is in Laya! !! " );
publishOptions.putHeader( "android-content-text", "The Story of Firfire is Cool" ); 
DeliveryOptions options=new DeliveryOptions();
MessageStatus message=Backendless.Messaging.publish(CreatePureChannelName(comment.getParent_post().getObjectId()),comment,publishOptions);

Hi Pujan,

Please, verify whether your service jar does not include classes from backendless.jar.

Hi, Pujan!

Please generate you business logic code again:

http://support.backendless.com/public/attachments/6172c674b90979db3f8b18d0808fb6c2.png</img>

and make sure that you use

com.backendless.services.messaging.MessageStatus

instead of

com.backendless.messaging.MessageStatus

in your code.

Hello @Anatolli
I removed this specific import of MessageStatus ( Tried after replacing the import Didn’t work too )

com.backendless.messaging.MessageStatus

So , I cleaned everything without this particular Import and Again after testing , It Gives me the Same Error as :

{
  "code": 0,
  "message": "Type:\"java.lang.NoSuchMethodError\", Description:\"com.backendless.Messaging.publish(Ljava/lang/Object;Lcom/backendless/messaging/PublishOptions;Lcom/backendless/messaging/DeliveryOptions;)Lcom/backendless/messaging/MessageStatus;\", ExceptionClass:\"ServiceException\"  {Msg:\"none\", Cause:\"none\"}"
}

While The Code I am using Now is VEry Very Simple as :

PublishOptions publishOptions = new PublishOptions();
//We are going to Recieve Some Sorts of HEader off here
//Just to make Things light on the Header part
publishOptions.putHeader( "android-ticker-text", "New Laya Intereaction" );
publishOptions.putHeader( "android-content-title", "A Laya User Rated "+String.valueOf(points)+" To Your Poem" );
publishOptions.putHeader( "android-content-text", "It has now "+ finalPoints+ " Points in total" );
DeliveryOptions deliveryOptions=new DeliveryOptions();
deliveryOptions.addPushSinglecast(sourcePost.getOriginal_poster().getProperty("device_id").toString());
Backendless.Messaging.publish((Object)"Test-Stufff",publishOptions,deliveryOptions);

Hi, Pujan!

Did you generate your business logic code once again? It it critical, because you need the latest version of generated files.
Please try it and tell the result.

Hello @Anatolii
I didn’t get you here actually . These are my Custom API Services rather than the Business Logic Code . Do You mean to say that I have to compile the Jar With the Latest version of Generated Files ?

In this case, just replace backendless.jar you use with the latest one.
