Android 5.0+ AudioManager setMode not working

I am working on AudioManager which is Android SystemService. with Android System 5.0+, I am facing an issue where AudioManager's setMode method is not working.

i via test, Android M, Lollipop .. 5.0+ version, AudioManager setMode doesn't work. Example:

public void initAudioImageIcon(boolean initLoad) {
    boolean isAudioHeaderMode = IMSharedPreferences.getBooleanExtra(this, IMSPConstant.SP_NAME_MESSAGE,
            IMSPConstant.SP_KEY_AUDIO_HEADER_MODE);


    if (isAudioHeaderMode) {
        mAudioHanderMode.setVisibility(View.VISIBLE);
        // audioManager.setMode(AudioManager.MODE_IN_CALL) , but android system 5.0+ no any change, getMode() == AudioManager.MODE_NORMAL
        setAudioMode(AudioManager.MODE_IN_CALL);
        audioManager.getStreamMaxVolume(AudioManager.STREAM_VOICE_CALL);
        if (!initLoad) {
            showAudioModePrompt(this.getText(R.string.im_audio_in_call), 1000);
        }
    } else {
        mAudioHanderMode.setVisibility(View.GONE);
        setAudioMode(AudioManager.MODE_NORMAL);
        if (!initLoad) {
            showAudioModePrompt(this.getText(R.string.im_audio_in_speeker), 1000);
        }
    }
}

but Android 3.0+, 4.0+ is ok, only 5.0+. therefore, I don't know where the errors are occurring.

With audio mode set to:

setMode(AudioManager.MODE_IN_COMMUNICATION);
setSpeakerphoneOn(false);


while my audio stream is set to STREAM_MUSIC, I can route audio to headphones easily. I tested it myself in AOSP Lollipop code.

Here in the question you never talked about the type of your stream. Set the stream to STREAM_MUSIC or STREAM_VOICE_CALL and the code will work for you too.

In android, Lollipop is setAudioMode(AudioManager.MODE_IN_CALL)

limited. It can only be used by system application with permission MODIFY_PHONE_STATE

. However, you can use MODE_IN_COMMUNICATION

it MODE_NORMAL

in regular applications too.
