Android Question Oject should first be intitialized(Java Object)

[petr4ppc]

Dear friends, please I have

        '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:

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

I get this error:

java.lang.RuntimeException: Object should first be initialized (JavaObject).

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

It is not related to Java / SDK.

Recognizer is not set anywhere. You need to set it or call InitializeNewInstance.

 

[petr4ppc]

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 :

setup.initialize(Me,Recognizer)

please are here other possibilities how can I do initialization of "Recognizer"?
Thank you
p4ppc

 

[Erel]

Can you post the code in setup.initialize?

 

[petr4ppc]

Here I send code:

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

setup.initialize(Main,Recognizer)

then appliacation not crashed (it is running), but Recognizer is not functioned.

Thank you very much,
p4ppc

 

[Erel]

Where is Recognizer initialized?

 

[petr4ppc]

With this code (I put now setup.InitializeStatic("mRecognizer"):

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

it appears you are trying to use this https://www.b4x.com/android/forum/threads/offline-continuous-speech-recognition.42898/post-259943, which is a 6 year old project which for some reason no longer runs. It may take some time, but I'll try to find out why. It may be that it won't run on newer Android versions, it has not been reported as non functional until now.

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)

@petr4ppc I've updated the project in the original thread, it now works on my Huawei P20 Pro Android 10.

Dear stevel05, thank you very much for your answer. I am trying your project on Android 11 and I am writing in my answer result:

I put my answer to main Continuous speech recognition thread here:
