自己用的东西

1.AsyncHttpClient使用单例模式

public class CustomerHttpClient {
    private static HttpClient customerHttpClient;
    
    private CustomerHttpClient() {
    }
    
    public static HttpClient getHttpClient() {
        if(null== customerHttpClient) {
            customerHttpClient =new DefaultHttpClient();
        }
        return customerHttpClient;
    }
}

2.client有取消请求的方法
public void cancelRequests(Context context, boolean mayInterruptIfRunning)

3.SoftRenference Bitmap 结合
