Android loopj Async Http在1.4.5更新后崩溃

标签： java android asynchronous httprequest loopj

Android loopj Async Http lib的新更新已经发布，它们发生了很大变化。现在您需要手动设置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.

在该消息之后它完全崩溃

我的Http请求课程：

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);
      }
}

任何人都可以帮助我吗？

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;
  }
}

我不同意Paul的做法。虽然我不能真正看到一种解决这个问题的好方法，因为我即将呈现的方式也是相当hacky，但不是使用AsyncHttpResponseHandler而是使用此类

public abstract class AlwaysAsyncHttpResponseHandler extends AsyncHttpResponseHandler {
    @Override
    public boolean getUseSynchronousMode() {
        return false;
    }
}

我用一个代码行解决它

我将responseHandler分开了

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);

答案 3 :(得分：2)

我通过在AsyncHttpResponseHandler（Looper.getMainLooper（））中传递参数解决了这个问题。

首先，我使用了两个类，一个是MainActivity和Download Class。在MainActivity类中，我调用在Downloadclass中实现的post方法。然后Download类包含从我的库导入的POST（），如import com.loopj.android.http。*;

MainActivity.Class 

clientObj.post(context,url,entity, "application/json", new AsyncHttpResponseHandler(Looper.getMainLooper()) {

@Override
public void onSuccess(int statusCode,org.apache.http.Header[] headers,byte[] responseBody) {
        System.out.println(" Success ="+responseBody);
}
@Override
public void onFailure(int statusCode,org.apache.http.Header[] headers,byte[] responseBody, Throwable error) {
    System.out.println( "Failure");
}
});

DownLoad.C​​lass 

    AsyncHttpClient asynClient = new AsyncHttpClient();


void post(Context context,String url, StringEntity entity,String string, AsyncHttpResponseHandler asyncHttpResponseHandler) {
    asynClient.addHeader("Accept", "application/json");
    asynClient.addHeader("Content-type", "application/json");
    asynClient.post(context, url, entity, "application/json", asyncHttpResponseHandler );
}

这是因为这个版本有几个错误。

我高度建议您使用OkHttp异步层，它的结构基本相同。

或者如果你想要基于OkHttpClient（Square Inc）的相同结构，请使用：
