Android loopj Async Http在1.4.5更新后崩溃 [英] Android loopj Async Http crashes after 1.4.5 update

问题描述

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。

The new update for Android loopj Async Http lib is out and they changed a lot. Now you need to manually set Looper.prepare() otherwise it uses synchronious mode instead of async by default. I don't get where I need to set it.

Logcat

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

After that message it totally crashes

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);
      }
}

任何人都可以帮助我吗？

Can anyone help me?

推荐答案

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。

I had a similar issue and found that making HTTP requests with an AsyncHttpClient in a thread caused the problem.

我在线程之外运行了我的HTTP请求，它解决了我的问题。你可以尝试类似的东西：

I ran my HTTP request outside of the thread and it fixed the problem for me. You can try something like:

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;
  }
}
