plyer 03-18 22:14:31.922 11532 11532 E SpeechRecognizer: not connected to the recognition service

[alessandro bonvicini]

Hello  everybody ,

i m trying to make the

https://github.com/kivy/plyer/tree/master/examples/speech2text

exmple work on my android 10 huaway phone

i receive the error in the  subject

in buildozer my permissions is set to

android.permissions = INTERNET, ACCESS_NETWORK_STATE, VIBRATE, RECORD_AUDIO, READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE

and the reuirements are

requirements = python3,kivy,plyer,SpeechRecognition,android

i granted manually permissions on my apk microphone and storage.

No one error arise form the log except for the one in subject  and the followings that are relevant, i think

PLEase may you help me to understand whats happening and to find a solution?

I really really need this piece of code working ...i am trying to demonstrate that kivy is a really productive technology in respect to java and others so for my target this way to simplify the access to java runtime si crucial

Thank  you a lot in advance

Adding thsi

03-18 22:48:24.197  4384  7224 E RecognitionService: call for recognition service without RECORD_AUDIO permissions
03-18 22:48:24.198  4384  4384 I A       : RecognitionService#onDestroy

i found the row above in the log  BUT i have RECORD_AUDIO set in my buildozer.spec.

Is this one a bug ? please help me.

[Robert]

PLEase may you help me to understand whats happening and to find a solution?

The permissions and requirements look like you are desperately guessing. Which is unlikely to work.

The approach that works is debugging using analysis.

I tried with the supplied buildozer.spec (changing kivy to kivy==2.0.0) and adding run time RECORD_AUDIO permission in main.py.

(the need to do that is a hint of neglected software)

It didn't work on an Android 11 device or an Android 6 device.

The idea of Plyer is very appealing, but in practice it does not always deliver. Don't assume it works.

Pyjnius works great, I use that a lot - Python syntax and semantics with specific Java class semantics added.

Trying a test case was a good approach.

If it works great, if not decide how much time you want to spend fixing it yourself or walk away.

[alessandro bonvicini]

Hi , you are absolutely right, i am not an expert in kivy or android programming so ,as you said, i just tried to guess.

But, i thank you  for your suggestions, i read that in andorid version > 8 yuo  have to set permission manually inside the runtime app.

I do not know how to do this from python , so an example is welcome. 

I'll try to approach  pyjinius....

tahnk you very much again 

[alessandro bonvicini]

Hello,

regarding this problem i set up the permission in

def build(self):
        request_permissions([Permission.INTERNET,Permission.RECORD_AUDIO])
        self.title = 'Recording Application'

This time the error on permission went away but there is always the following exception  the destroy the recognition  service

Someone can help me?

[Robert]

Pyjnius is certainly jumping in at the deep end of the swimming pool.

The message says an Intent.getStringExtra() call is being passed a character array, but the recipient expects a Java String.

It looks like this occurs when the RecognitionSevice Listener starts.

Seems a reasonable the char array is coming from Python.

Looking at the Plyer code   https://github.com/kivy/plyer/blob/master/plyer/platforms/android/stt.py

Perhaps one or two of the putExtra() arguments needs a cast to java.lang.String ?

But, there is more research to do......

A quick look at the putExtra() documentation shows that it is heavily overloaded, and both String and char[] are legal.

https://developer.android.com/reference/android/content/Intent

So this would probably not be caught till run time.

But it there are other choices, Parcelable[], String[], or Bundle are also possibilities.

If you don't want to dig through the RecognitionService documentation, String seems like a good first try.

Unrelated, FYI, and not wrong:

INTERNET does not need to have a run time permission because it does not have a protection_level "dangerous"

https://developer.android.com/reference/android/Manifest.permission#INTERNET
