[dingusagar]

2 phones got connected successfully. But when I try to launch the gallery and click an image , the app crashes. Please help

The error message tells that the device.deviceAddress is null in the onActivityResult of DeviceDetailsFragment.java [--------code-snippet---- @Override public void onActivityResult(int requestCode, int resultCode, Intent data) {

	String localIP = Utils.getLocalIPAddress();
	// Trick to find the ip in the file /proc/net/arp
	String client_mac_fixed = new String(device.deviceAddress).replace("99", "19");
	String clientIP = Utils.getIPFromMac(client_mac_fixed);
