Zasadniczo mam główną klasę prowadzącą cały projekt. Kod działa doskonale, ale gdy aplikacja jest nieostra, staje się nieaktywna. Zastanawiałem się, w jaki sposób chciałbym zrobić z tego usługę. Jeden, który uruchamia się przy starcie.aSmack as a service
Aplikacja będzie jednokierunkowym systemem komunikatów dla powiadomień. TO ZNACZY.
Pulpit Client -> Openfire Server -> Android XMPP Service -> Storage (DB) -> Android GUI dla wyświetlacza
jak mówiłem, Kodeks pracuje (Connect Login, odbiór) ale ISN Usługa.
Mogę użyć źródła BEEM, ale jest zbyt polecane i z przeplotem. Jestem po lekkiej służbie.
Kod:
public class MainActivity extends Activity {
public static final String HOST = "fire.example.com";
public static final int PORT = 5222;
public static final String SERVICE = "example.com";
public static final String USERNAME = "[email protected]";
public static final String PASSWORD = "mepass";
private XMPPConnection connection;
private ArrayList<String> messages = new ArrayList<String>();
private Handler mHandler = new Handler();
private ListView listview;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listview = (ListView) this.findViewById(R.id.listMessages);
setListAdapter();
connect();
}
/**
* Called by Settings dialog when a connection is establised with
* the XMPP server
*/
public void setConnection(XMPPConnection connection) {
this.connection = connection;
if (connection != null) {
// Add a packet listener to get messages sent to us
PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
connection.addPacketListener(new PacketListener() {
@Override
public void processPacket(Packet packet) {
Message message = (Message) packet;
if (message.getBody() != null) {
String fromName = StringUtils.parseBareAddress(message.getFrom());
Log.i("XMPPChatActivity ", " Text Recieved " + message.getBody() + " from " + fromName);
messages.add(message.getBody());
mHandler.post(new Runnable() {
public void run() {
setListAdapter();
}
});
}
}
}, filter);
}
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@SuppressLint("NewApi")

listview.setAdapter(adapter);
}
@Override

super.onDestroy();

connection.disconnect();
} catch (Exception e) {
}
}
public void connect() {
final ProgressDialog dialog = ProgressDialog.show(this, "Connecting...", "Please wait...", false);
Thread t = new Thread(new Runnable() {
@Override
public void run() {
// Create a connection
ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT, SERVICE);
XMPPConnection connection = new XMPPConnection(connConfig);
try {
connection.connect();
Log.i("XMPPChatActivity", "[SettingsDialog] Connected to "+connection.getHost());
} catch (XMPPException ex) {
Log.e("XMPPChatActivity", "[SettingsDialog] Failed to connect to "+ connection.getHost());

setConnection(null);
}
try {

Log.i("XMPPChatActivity", "Logged in as" + connection.getUser());
// Set the status to available
Presence presence = new Presence(Presence.Type.available);
connection.sendPacket(presence);
setConnection(connection);
Roster roster = connection.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
for (RosterEntry entry : entries) {
Log.d("XMPPChatActivity", "--------------------------------------");
Log.d("XMPPChatActivity", "RosterEntry " + entry);
Log.d("XMPPChatActivity", "User: " + entry.getUser());
Log.d("XMPPChatActivity", "Name: " + entry.getName());
Log.d("XMPPChatActivity", "Status: " + entry.getStatus());
Log.d("XMPPChatActivity", "Type: " + entry.getType());
Presence entryPresence = roster.getPresence(entry.getUser());
Log.d("XMPPChatActivity", "Presence Status: "+ entryPresence.getStatus());
Log.d("XMPPChatActivity", "Presence Type: " + entryPresence.getType());
Presence.Type type = entryPresence.getType();
if (type == Presence.Type.available)
Log.d("XMPPChatActivity", "Presence AVIALABLE");
Log.d("XMPPChatActivity", "Presence : " + entryPresence);
}
} catch (XMPPException ex) {
Log.e("XMPPChatActivity", "Failed to log in as "+ USERNAME);
Log.e("XMPPChatActivity", ex.toString());
setConnection(null);
}
dialog.dismiss();
}
});
t.start();
dialog.show();
}
}
Więc zasadniczo Jak zrobić to usługa
