Dear friends, please I have
B4X: 
        'Declared
        Private Recognizer As JavaObject
        'Then
        Dim Evt As Object = Recognizer.CreateEvent("edu.cmu.pocketsphinx.RecognitionListener","Listener",0)
        Recognizer.RunMethod("addListener",Array(Evt))

but here:

B4X: 
Recognizer.RunMethod("addListener",Array(Evt))

I get this error:


The mistake is born after I set higher Java or SDK platform, please how can I rewrite the code?
I set:
java\jdk-11.0.1\bin\javac.exe
androidsdk\platforms\android-30\android.jar

Best

Thank you Erel,
only notice: I think that something must happen because of changing Java or Platform version (now 30) because with older platform (15) and Java 1 0 7 11, was everything ok.. (but I am not proffesional, I am only writing all informations).

I am doing recognizer initialization in :
B4X: 
setup.initialize(Me,Recognizer)

please are here other possibilities how can I do initialization of "Recognizer"?
Thank you

Here I send code:
B4X: 
Sub Class_Globals
Dim mModule as Object
Dim MRecognizer as JavaObject
Private TH As Thread
End Sub

Public Sub Initialize(Module as Object,Recognizer as JavaObject)
mModule=Module
mecognizer=Recognizer
TH.initialise("TH")
TH.start(Me,"Configurerecognizer_new",Null)
End sub

I am trying only - I have tried to put MAIN (not Me):
If I set
B4X: 
setup.initialize(Main,Recognizer)
then appliacation not crashed (it is running), but Recognizer is not functioned.

Thank you very much,
p4ppc

With this code (I put now setup.InitializeStatic("mRecognizer"):
B4X: 
Private Sub Configurerecognizer_new
    Dim Setup As JavaObject
    Setup.InitializeStatic("edu.cmu.pocketsphinx.SpeechRecognizerSetup")
    mRecognizer = Setup.RunMethodJO("defaultSetup",Null) _
    .RunMethodJO("setAcousticModel",Array(JavaFile(ModelsDir,"hmm/en-us-semi"))) _
    .RunMethodJO("setDictionary",Array(JavaFile(ModelsDir,"dict/cmu07a.dic"))) _          
    .RunMethodJO("setRawLogDir",Array(JavaFile(rawdir,""))) _                        
    .RunMethodJO("setKeywordThreshold",Array(Val)) _
    .Runmethod("getRecognizer",Null)    

    Dim ModuleJO As JavaObject = mModule
    mRecognizer.RunMethod("addKeyphraseSearch",Array(ModuleJO.GetField("_kws_search"), ModuleJO.GetField("_keyphrase_search"))) 
    setup.InitializeStatic("mRecognizer")  
End Sub
App is running without recognition and I get in Logs
Failed to initialize recognizer systemException: java lang mRecognizer

Erel, Stevel05

thank you for your answer.
Yes I am trying to use this old project and it appears that in newer version of Android it can not running as in older version (3-4 years back) of Android.
Please if you will have some informations how to solve
"java.lang.RuntimeException: Object should first be initialized (JavaObject) "
because of calling
Recognizer.RunMethod("addListeenr",Array(Evt))
then please for information...

(I am trying : Platform - Android 30, java - JDK 11 0 1)

Thank you very much
Best regards
p4ppc
(I will try some other tests myself too, but I dont know if I can do Initialization correctly)
