Android loopj Async Http在1.4.5更新后崩溃

http

runtime

java

Android loopj Async Http lib的新更新已经发布,并且它们发生了很大变化.现在你需要手动设置,Looper.prepare()否则它默认使用同步模式而不是异步.我没有得到我需要设置的地方.

logcat的

07-09 08:16:18.775: W/AsyncHttpResponseHandler(6606): Current thread has not called Looper.prepare(). Forcing synchronous mode.

在那个消息之后它完全崩溃了

我的Http请求类:

import android.os.Looper;

import com.loopj.android.http.AsyncHttpClient;
import com.loopj.android.http.AsyncHttpResponseHandler;
import com.loopj.android.http.PersistentCookieStore;
import com.loopj.android.http.RequestParams;

public class HttpRequest {
      public static AsyncHttpClient client = new AsyncHttpClient();

      public static void setCookieStore(PersistentCookieStore cookieStore) {
            client.setCookieStore(cookieStore);
        }

      public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
          Looper.prepare();
          client.get(url, params, responseHandler);
      }

      public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
          Looper.prepare();
          client.post(url, params, responseHandler);
      }
}

谁能帮我？

我不同意保罗的做法.虽然我不能真正看到解决这个问题的好方法,因为我即将呈现的方式也相当hacky,但不是使用AsyncHttpResponseHandler而是使用此类代替
```
public abstract class AlwaysAsyncHttpResponseHandler extends AsyncHttpResponseHandler {
    @Override
    public boolean getUseSynchronousMode() {
        return false;
    }
}
```

我用一个代码行解决

我分离了我的responseHandler

JsonHttpResponseHandler responseHandler = new JsonHttpResponseHandler(){


            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                RecorridoResponseDTO respuesta= new Gson().fromJson(response.toString(), RecorridoResponseDTO.class);
                recorrido.setRecorridoId(respuesta.getA());
                mDataManager.actualizarRecorrido(recorrido);
                try {
                    Thread.sleep(10000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

            }


            @Override
            public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
                super.onFailure(statusCode, headers, throwable, errorResponse);
            }


        } ;

这是圣线

responseHandler.setUsePoolThread(true);

我遇到了类似的问题,发现在线程中使用AsyncHttpClient发出HTTP请求会导致问题.

我在线程之外运行了我的HTTP请求,它解决了我的问题.您可以尝试以下方式:

public class HttpRequest {

  // A SyncHttpClient is an AsyncHttpClient
  public static AsyncHttpClient syncHttpClient= new SyncHttpClient();
  public static AsyncHttpClient asyncHttpClient = new AsyncHttpClient();

  public static void setCookieStore(PersistentCookieStore cookieStore) {
      getClient().setCookieStore(cookieStore);
  }

  public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      getClient().get(url, params, responseHandler);
  }

  public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      getClient().post(url, params, responseHandler);
  }

  /**
   * @return an async client when calling from the main thread, otherwise a sync client.
   */
  private static AsyncHttpClient getClient()
  {
      // Return the synchronous HTTP client when the thread is not prepared
      if (Looper.myLooper() == null)
          return syncHttpClient;
      return asyncHttpClient;
  }
}
