@GWAK ==== i dont understand:  
the previous code you posted was:

```auto
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);

```

and it is the same… The unique explanation i can see is the first CHANNEL\_ID uses a string with forbidden chars but in this case why it does not fire an error?

@akenaton

I will tell you about my test.

1. Processing Does not work on Android 3.0.
2. Processing Works with Android 4.0.
3. 

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder (getContext ())

mBuilder.setChannelId (CHANNEL\_ID);

The channel ID input was sent to mBuilder. I do not know why, but it worked.

@GWAK ===

@akenaton

Dear akenaton,  
Good morning.

I’m talking about Android mode version.

In Android mode 3.0  
'mBuilder.setChannelId (CHANNEL\_ID); 'Error.

However, in Android mode 4.0  
'mBuilder.setChannelId (CHANNEL\_ID); ’  
It works.

This solved ‘Notification’.

 ![t2](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/d/d246095483309f814f08e2ce26d2bf8ccde0e6d2.jpeg) ![tt](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/7/73a43ff9ceb06e6a4d8e11ca19a42342bade1602.jpeg)

But there was a problem.  
Text is broken after Android Mode 4.0  
help me.

@akenaton I think he means [this](https://android.processing.org/install.html) previous mode.

</div>

@noel ===  
yes i think also, but the 2 codes are quite (the string declared for CHANNEL\_ID is the unique change) the same and as he never speaks about 4.0/3.0 before how can you guess and help  
BTW : i see that you have put in github something about “onPause()” bug; as i never got any problem with onPause() can you put some code snippet to verify?

The code that verifie’s it is on the same issue in github.
