TextToSpeech on bluetooth SCO

TextToSpeech on bluetooth SCO - android

I am trying to route my TTS output to an external bluetooth SCO device (works fine with local speaker and mic) but it doesn't play out.
I am setting the route for AudioManager as follows -
AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.startBluetoothSco();
audioManager.setBluetoothScoOn(true);
The utterances are played out with this method -
private void say(String text, String utteranceId) {
Log.d(TAG, "Saying: " + text);
final Bundle ttsParams = new Bundle();
ttsParams.putInt(TextToSpeech.Engine.KEY_PARAM_STREAM, AudioManager.STREAM_VOICE_CALL);
mTextToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, ttsParams, utteranceId);
}
There's no audio from the speaker. If I don't setBluetoothScoOn to true it works fine with the in-built speaker.

Use this class:
public abstract class BluetoothHeadsetUtils {
private AudioManager mAudioManager;
private BluetoothAdapter mBluetoothAdapter;
private BluetoothHeadset mBluetoothHeadset;
private BluetoothDevice mConnectedHeadset;
private Context mContext;
private CountDownTimer mCountDown;

final int intExtra = intent.getIntExtra(BluetoothHeadset.EXTRA_STATE, BluetoothHeadset

Use your say method in the onScoAudioConnected callback.

You are getting the exception because in class ObdGatewayService your class member mChatservice is not the same as mChatservice in class LiveFragment
They are just different member variables
mChatservice gets assigned like this in your Fragment
mChatService = new BluetoothChatService(getActivity(), mHandler);
You need to pass this reference to ObdGatewayService 's startService() like this where ever you are instantiating/invoking it:-
ObdGatewayService ogs;
....
ogs.startservice(mChatservice); // This is fragment's member reference
And in ObdGatewayService you have to assign it accordingly:-
public void startService(BluetoothChatService _mChatservice) throws IOException {
Log.d(TAG, "Starting service..");
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
mChatservice = _mChatservice //Assignment YOU ARE MISSING THIS
.......
.......

Bluetooth streaming is lagging Android app

I'm writinng Android app that receiving data via bluetooth from another device. Those data as in fact streaming non-stop. After getting about 50 or 70 of them, app slows down and stop showing me received data. App cache is full, but clearing it (deleting context.getCacheDir()) doesn't help. After restarting whole app, I can again get next part of data. WHat can I do for avoiding this "lag"?

Getting incoming calls for an hour only using Twilio

I have implemented Twilio in my android app for outgoing and incoming calls. But I'm facing an issue while getting incoming call with the background service. The issue is that I get calls in first 30-40 mins only. After sometime phone stops getting incoming calls. I tried so much. Please respond me soon. I'm sharing code with you too.
I get token from a background service which generates token after a time period.

Android speech recognizer works fine on 5.0.1 but doesn't work on 5.1

I am working on create a speech recognition service on android and followed previous works from others here. The old version was based on android 5.0.1 and it worked perfectly fine.
However, when I try to move it to android 5.1, it always stops in the onError function in the recognition listener with a error code 7, which means ERROR_NO_MATCH.
I don't know why this happened. is there any difference on using speech recognizer in Android 5.0.1 and 5.1?
If someone can help me, I will be very appreciated. Thanks.
Here is my code:
