Change the method signature to:

 public void print(final BA ba, final String filePath,final String printerIP){

 

[buras3]

Tank you Erel

Can you tell me how can I show the error code -
printResult.errorCode.toString()
In ba ?

then error now is unknown "metadata" because I copied it and i don't know how to raise/show the
"eventName" + "_metadata" part

 

[Erel]

You can use BA.Log(printResult.errorCode.toString());

Change the code to:

ba.raiseEventFromDifferentThread(this , null, 0, "myevent_metadata", true, new Object[] {printResult.errorCode.toString()});

Handle it in your B4A code with:

Sub Myevent_Metadata (ErrorCode As String)

Tank you It's working
But i still get error_socket_error
what else can I check ?
I already talked with Brother Support
and tried with a few Api's

I can print with https://play.google.com/store/apps/details?id=com.brother.ptouch.sdk.printdemo&hl=en with no problem
and it's the same code

 

[Erel]

The code I've posted should raise the event. Use BA.Log to see whether the code is reached or not.

 

[buras3]

the event is raising ok

when I add ba.log
I get "cannot find symbol"
I tried
ba.log()
ba.log("","")
ba.log 1
ba.log "1"

how to write it?

 

[DonManfred]

BA.Log("Text")

 

[buras3]

I tried that
in the java code yes?

 

[DonManfred]

sure in java-code.
It is a java-call to a method of a import of b4a-core

 

[buras3]

so how this is working : ba.raiseEventFromDifferentThread
and this not ba.log("test");
?

 

[buras3]

maybe that is the problem with the socket error ? I need to import for network?
this is the imports

import com.brother.ptouch.sdk.*;

import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.*;

 

[Erel]

No. If there were imports problems then it would fail to compile.

 

[buras3]

where can I see the ba class?

 

[Erel]

ba is explained here: https://www.b4x.com/android/forum/threads/java-creating-libraries-for-basic4android.6810/

 

[buras3]

this is the log i get
i have tried to fix the fatal signal with CallSubDelayed
but it's the same

[Erel]

Fatal signal is not a regular error. It is a low level error.

You will need to connect in USB debug mode and monitor the unfiltered logs. There might be more information there.

I don't know how but I reinstall the printer and it's working!!
no change with the code
Tank you very much
