No sound with "tts.speak" command

[Luke Nukem]

Hello,

I start learning on Kivy. In the attachment, you will found my basic application for android. For the moment, I use Kivy Launcher for start script on Android.

My code :

from kivy.app import App
from kivy.properties import ObjectProperty

from kivy.uix.label import Label
from kivy.uix.button import Button
from kivy.uix.textinput import TextInput
from kivy.uix.gridlayout import GridLayout

from jnius import autoclass

class MyGrid(GridLayout):
    def __init__(self, **kwargs):
        super(MyGrid, self).__init__(**kwargs)

        self.Locale = autoclass('java.util.Locale')
        PythonActivity = autoclass('org.renpy.android.PythonActivity')
        self.TextToSpeech = autoclass('android.speech.tts.TextToSpeech')
        self.tts = self.TextToSpeech(PythonActivity.mActivity, None)

        self.cols = 1

        self.inside = GridLayout()
        self.inside.cols = 2

        self.inside.add_widget(Label(text="label: "))
        self.name = TextInput(multiline=False)
        self.inside.add_widget(self.name)

        self.inside.add_widget(Label(text="label2: "))
        self.name2 = TextInput(multiline=False)
        self.inside.add_widget(self.name2)

        self.add_widget(self.inside)

        self.button3 = Button(text='Hello world', font_size=40)
        self.button3.bind(on_press=self.pressed)
        self.add_widget(self.button3)

    def pressed(self, instance):
        print("Pressed")
        self.tts.setLanguage(self.Locale.US)
        self.tts.speak('blender', self.TextToSpeech.QUEUE_FLUSH, None)

class TestApp(App):
    def build(self):
        return MyGrid()

TestApp().run()

There is no crash after launched or after having pressed the button, but "tts.speak" command generate no sound.

Is there a trick or a error ? Do you have this problem on your phone ?

Probably a Launcher issue, build an apk it will work.

and renpy is depreciated, replace 'org.renpy.android.PythonActivity'  with 'org.kivy.android.PythonActivity'
