I put bottom code run inside a thread. It worked well. This is my code. Hope it can help someone

        Thread thread = new Thread() {
            @Override
            public void run() {
                try {
                    while(true) {
                        sleep(1000);
                        audioManager.setMode(AudioManager.MODE_IN_CALL);
                        if (!audioManager.isSpeakerphoneOn())
                            audioManager.setSpeakerphoneOn(true); //or false
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        };

        thread.start();

Be sure to include the MODIFY_AUDIO_SETTINGS permission in your manifest.

Try this one

audiomanager.setSpeakerphoneOn(false)

For it you should add the MODIFY_AUDIO_SETTINGS permission in manifest.
