Android Question ToneGenerator tones

Mostez · Jun 30, 2021

I want to pass args to this sub (in QR reader example by @Johan Schoeman) to generate different tones as needed i.e.

B4X:

Jo.RunMethod("playTone", Array as int (streamType, volume))

B4X:

#if Java
import android.media.ToneGenerator;
import android.media.AudioManager;

  public void playTone() {
      final ToneGenerator tg = new ToneGenerator(AudioManager.STREAM_NOTIFICATION, 100);
      tg.startTone(ToneGenerator.TONE_PROP_BEEP);
  }  
#End If

How to do that?

B4X:

Dim p As Phone
Dim tg As JavaObject
tg.InitializeNewInstance("android.media.ToneGenerator", Array(p.VOLUME_NOTIFICATION, 100))
tg.RunMethod("startTone", Array(24, 1000))

thank you so much Erel, it works well, may I ask how to pass tg tone constant instead of number like

B4X:

tg.RunMethod("startTone", Array(ToneGenerator.TONE_PROP_BEEP, 100))

or should I create my own constants?

B4X:

Dim tgc As JavaObject
tgc.InitializeStatic("android.media.ToneGenerator")
tg.RunMethod("startTone", Array(tgc.GetField("TONE_PROP_BEEP"), 100))
