从

networkThread = new HandlerThread("Network Thread");
    if(networkThread.getLooper() == null)
        networkThread.run();

handler = new Handler(networkThread.getLooper());
handler.postDelayed(updateTask, 1000);

到

// Create and start a handler thread.
networkThread = new HandlerThread("Network Thread");
networkThread.start(); 

handler = new Handler(networkThread.getLooper()); // The calling thread must wait until a Looper has been created in the handler thread.

// Post your task to handler thread to process
handler.postDelayed(updateTask, 1000);
