Я использую BroadcastReceiver, IntentService для фоновых операций и передаю данные на Activity. Насколько я знаю, IntentService выполняется в отличается от UI нити, тем не менее, у меня есть android.os.NetworkOnMainThreadExceptionandroid.os.NetworkOnMainThreadException in onHandleIntent метод IntentService
метод регистрации BroadcastReceiver:
private void registerReceiver()
{
// создаем BroadcastReceiver
bCarBroadcast = new BroadcastReceiver() {
// действия при получении сообщений
public void onReceive(Context context, Intent intent) {
int status = intent.getIntExtra(Constants.CAR_SEARCH_STATUS, 0);
int task = intent.getIntExtra(Constants.CAR_SEARCH_TASK, 0);
Log.d(TAG, "onReceive: task = " + task + ", status = " + status);
if (status == Constants.STATUS_RUNNING) {
beginProgressTask();
}
if (status == Constants.STATUS_FINISHED) {
String data = intent.getStringExtra(Constants.CAR_SEARCH_DATA);
if(data!=null)
car_search_result_str.setText(data);
}
}
};
IntentFilter intFilt = new IntentFilter(Constants.BROADCAST_ACTION);
registerReceiver(bCarBroadcast, intFilt);
}
OnCreate:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.car_search_activity);
registerReceiver();
Intent a= new Intent(this, OrderStateService.class);
startService(a);
}
и IntentService:
public class OrderStateService extends IntentService {
private static final String TAG = "OrderStateService";
private JSONObject jsonResponse;
public OrderStateService() {
super("OrderStateService");
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
onHandleIntent(intent);
return START_REDELIVER_INTENT;
}
@Override
public void onStart(Intent intent, int startId) {
onHandleIntent(intent);
}
@Override
protected void onHandleIntent(Intent intent) {
Intent intentResult = new Intent(Constants.BROADCAST_ACTION);
intent.putExtra(Constants.CAR_SEARCH_STATUS, Constants.STATUS_RUNNING);
sendBroadcast(intentResult);
final Bundle data = new Bundle();
DefaultHttpClient httpclient = new DefaultHttpClient();
String url = Constants.HOST_URL + "/api/version/";//Constants.ORDER_URL + intent.getStringExtra(Constants.ORDER_ID);
Log.i(TAG, url);
HttpGet httpget = new HttpGet(url);
// Some try and catch that I am leaving out
try {
httpget.addHeader("Authorization", SharedPrefsSingleton.getInstance().getSharedPrefs().getString(Constants.USER_AUTHORIZATION, null));
httpget.addHeader("Content-Type", "application/json");
httpget.addHeader("Accept", "application/json; charset=utf-8");
httpclient.execute(httpget);
HttpResponse response = (HttpResponse) httpclient.execute(httpget);
;
Log.i(TAG + " code", Integer.toString(response.getStatusLine().getStatusCode()));
HttpEntity entity = response.getEntity();
if (entity != null) {
// Read the content stream
InputStream instream = entity.getContent();
Header contentEncoding = response.getFirstHeader("Content-Encoding");
if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) {
instream = new GZIPInputStream(instream);
}
// convert content stream to a String
String resultString = Utils.getStringFromInputStream(instream);
instream.close();
response.getEntity().consumeContent();
// Transform the String into a JSONObject
jsonResponse = new JSONObject(resultString);
Log.i(TAG, jsonResponse.toString());
if (jsonResponse.has("order_car_info"))
{
data.putString(Constants.RECEIVER_DATA, "Error");
}
else
{
data.putString(Constants.RECEIVER_DATA, jsonResponse.toString());
intent.putExtra(Constants.CAR_SEARCH_STATUS, Constants.STATUS_FINISHED);
intent.putExtra(Constants.CAR_SEARCH_DATA, jsonResponse.toString());
sendBroadcast(intent);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

You не следует вызывать 'onHandleIntent()' самостоятельно. Кроме того, я не считаю, что вам нужно переопределять 'onStart()' или 'onStartCommand()' вообще. –
Спасибо, проблема решена –
