Greetings,
I've been looking around to find an answer for this. But with no results. :sign0085:
I took the Bluetooth chat Example from Android's Sample codes
BluetoothChat - Bluetooth Chat | Android Developers
And i've worked around with it but the only thing that I've made proggress is to make the bluetooth device name to be showed like link so users can press on it and check the picture, but its not what i really need.
I'd Love to make it appear the image immediately on the list after the search, which will download over internet connection, but appearing in the app, not opening the browser and then displaying.
The Code that needs modifing is
`public class DeviceListActivity extends Activity {
// Debugging
private static final String TAG = "DeviceListActivity";
private static final boolean D = true;
// Return Intent extra
public static String EXTRA_DEVICE_ADDRESS = "device_address";
