Java Question (java) BA.raiseEvent

[Mrjoey]

hello , i need to raise and event on my activity or service , from a java library , i ve seen some threads about it , and i found that u can make it in 2 ways , adding some lines inside the library , or use javaobject , i need some example , simple event with 1 argument or no arguments , tnx

JavaObject should be used from B4A code not Java code.

Add a BA parameter to your method signature. The compiler will then add the BA object automatically.

You can then call ba.raiseEvent(...). Remember that the sub names are lower cased.

i have a this code :

    @ShortName("SyncProcess")   
    public static class Syncprocesses{
        public boolean IsEnded = false;
        public BASS.SYNCPROC syncproc = new BASS.SYNCPROC() {
           
            public void SYNCPROC(int handle, int channel, int data, Object user) {
// i need to raise an event from here
                IsEnded = true;
            }
        };
       
    }

can u please tell me what to do and how to implement ba.raseEvent ? thank u

 

[Erel]

Something like:

@Events(values={"SyncProc(Handle As Int, Channel As Int, Data As Int, User As Object)"})
private BA ba;
private String eventName;
public void Initialize(BA ba, String EventName) {
 this.ba = ba;
 this.eventName = EventName.toLowerCase(BA.cul);
}
...
public void SYNCPROC(...) {
 ba.raiseEvent(null, eventName + "_syncproc", handle, channel, data, user)
}

Mr Erel i think u misunderstood my point , i need to raise an event from my java library to b4a activity or process not raising a event to a sub inside the java library.

Mr Erel i think u misunderstood my point , i need to raise an event from my java library to b4a activity or process not raising a event to a sub inside the java library.

This is what Erel's code do.
In the Initialize() function you tell the java lib the event sub name. And then with raiseEvent() you call the B4A event sub.
In your B4A code you must create "Sub eventname_SyncProc(Handle As Int, Channel As Int, Data As Int, User As Object)"
