これは私のサービスを呼び出すクラスです：
public class TicketList extends ListActivity
{
private ArrayList<Tickets> alTickets = new ArrayList<Tickets>();
private boolean listCreated = false;
private static Drawable background = null;
private Resources res;
private Tickets ticket = null;
private TicketConnector localService;
/**
* Called when the activity is first created.
*
*/
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.ticketlist);
if(!listCreated)
{
connectService();
//populateList();
res = getResources();
background = res.getDrawable(R.drawable.background);
listCreated = true;
}
TicketAdapter StatisticsAdapter = new TicketAdapter(this, alTickets);
setListAdapter(StatisticsAdapter);
}
/**
* Populates the ListView.
* This needs to be done once the Activity is created and if the menu entry refresh is hit.
*/
private void populateList()
{
try
{
String jsonString = localService.queryData(new String[] {"getTicketList"}, new String[] {"Offen"});
//String jsonString = new TicketConnector().queryData(new String[] {"getTicketList"}, new String[] {"Offen"});
JSONObject jsonObj = new JSONObject(jsonString);
JSONArray ticketArray = jsonObj.getJSONArray("tickets");
Tickets[] tickets = new Tickets[ticketArray.length()];
for (int i=0;i<ticketArray.length();i++)
{
JSONObject object = ticketArray.getJSONObject(i).getJSONObject("ticket");
ticket = new Tickets(object.getString("id"), object.getString("color"), object.getString("priority"));
alTickets.add(ticket);
}
}
catch (Exception e)
{
Log.e("DayTrader", "Exception getting JSON data", e);
}
}
private void connectService()
{
Intent intent = new Intent(getApplicationContext(), TicketConnector.class);
bindService(intent, connection, Context.BIND_AUTO_CREATE);
}
public void getData()
{
String s = localService.queryData(new String[] {"getTicketList"}, new String[] {"Offen"});
}
ServiceConnection connection = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name, IBinder binder)
{
Toast.makeText(TicketList.this, "Service connected",Toast.LENGTH_SHORT).show();
localService = ((TicketConnector.LocalBinder)binder).getService();
Log.i("INFO", "Service bound: TicketConnector");
}
@Override
public void onServiceDisconnected(ComponentName name)
{
Toast.makeText(TicketList.this, "Service disconnected",Toast.LENGTH_SHORT).show();
localService = null;
Log.i("INFO", "Service unbound: TicketConnector");
}
};
}
そしてこれはサービスです：
public class TicketConnector extends Service
{
private SharedPreferences settings = null;
// This is the object that receives interactions from clients. See
// RemoteService for a more complete example.
private final IBinder binder = new LocalBinder();
private String username = null;
private String password = null;
private String server = null;
private String port = null;
private String urlStr = null;
private String result = null;
@Override
public void onCreate()
{
settings = CMDBSettings.getSettings(this);
username = settings.getString("username", "");
password = settings.getString("password", "");
server = settings.getString("server", "");
port = settings.getString("serverport", "");
}
@Override
public IBinder onBind(Intent intent)
{
return binder;
}
@Override
public void onDestroy()
{
}
public String queryData(String[] actions, String[] category)
{
//http://localhost:8080/MobileCMDB/TicketListener?format=json&actions=getTicketList&ticketcategory=Open
urlStr = "http://"+server+":"+port+"/MobileCMDB/TicketListener?format=";
new jsonParser().execute(actions);
return result;
}
abstract class BaseParser extends AsyncTask<String, Integer, String>
{
protected BaseParser(String format)
{
urlStr += format;
}
private String makeUrlString(String[] actions, String[] category)
{
StringBuilder sb = new StringBuilder(urlStr);
for (int i=0;i<actions.length;i++)
{
sb.append("&actions=");
sb.append(actions[i]);
sb.append("&ticketcategory=");
sb.append(category[i]);
}
return sb.toString();
}
protected InputStream getData(String[] actions, String[] category) throws Exception
{
URI uri = new URI(makeUrlString(actions, category));
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(uri);
request.addHeader("Accept-Encoding","gzip");
HttpResponse response = client.execute(request);
InputStream content = response.getEntity().getContent();
Header contentEncoding = response.getFirstHeader("Content-Encoding");
if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip"))
{
content = new GZIPInputStream(content);
}
return content;
}
@Override
protected void onPostExecute(String jsonString)
{
result = jsonString;
}
}
private class jsonParser extends BaseParser
{
public jsonParser()
{
super("json");
}
@Override
protected String doInBackground(String... actions)
{
String[] category = new String[] {"Open"};
StringBuilder json = null;
try
{
json = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(getData(actions, category)));
String line = reader.readLine();
while (line != null)
{
json.append(line);
line = reader.readLine();
}
}
catch (Exception e)
{
Log.e("PrimeCMDB - Network", "Exception getting JSON data", e);
}
return json.toString();
}
}
/**
* Class for clients to access. Because we know this service always
* runs in the same process as its clients, we don't need to deal with
* IPC.
*/
public class LocalBinder extends Binder
{
public TicketConnector getService()
{
return TicketConnector.this;
}
}
}
これは、AndroidManifest.xmlの2つのアクティビティです。
<activity
android:name=".ticket.TicketList"
android:label="@string/ticket"
/>
<service
android:name=".network.TicketConnector"
android:enabled="true"
/>
onServiceConnectedは実行されません。私は何か見落としてますか？
チケットリストアクティビティをアクティブ化したときの冗長モードでのLogCatの出力は次のとおりです。
