Answer 1

After many check and investigation i have found the problem. i am answering it here if someone else will have the same problem.

i have notice that the voice is not routed to the speaker but to the ear cap...so i add the bellow code to turn on the speaker and the problem has solved !

    audioManager = (AudioManager) this.activity.getSystemService(Context.AUDIO_SERVICE);
    audioManager.setSpeakerphoneOn(true);
    audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);

To answer the question where i put the code, i have actually add a new icon to give the user to switch between headset and speaker.

here is the full code:

    toggleSpeakerHeadset.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (speakerOn) {
                setHeadsetOn();
            } else {
                setSpeakerOn();
            }
        }
    });

private void setSpeakerOn() {
    speakerOn = true;
    toggleSpeakerHeadset.setImageResource(R.drawable.headset);
    audioManager.setSpeakerphoneOn(true);
    audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
}

private void setHeadsetOn() {
    speakerOn = false;
    toggleSpeakerHeadset.setImageResource(R.drawable.speaker);
    audioManager.setSpeakerphoneOn(false);
    audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
}
