Send data from Thread to Activity / Fragment

In my application I receive a data stream via bluetooth. For this purpose I've created a BluetoothService class which has several threads to communicate with the bluetooth device. In this class I have also a Thread which receives the data from an InputStream. The data is received very fast (every 10ms). Receiving of the data stream is working well.

Now I am asking myself how to transport that data to my current activity in order to display (plot) the received data. This should be done in an efficient way. I guess sending broadcasts or somthing like that is too inefficient. Is there some sort of fast event queue or something similar?

How can I send the data from the receiving thread in the service to my activity/fragment?

kind regards

you can use runOnUiThread or you can use Handler or you can use AsyncTask and the progressPublish()method or you can use post method of widgets.

You should look into Bound services.
