OkHTTP和Picasso不会一起运行

Question

我在我的项目中使用Picasso库来加载图像和缓存它们.它没有任何问题,效果很好.但是,当我尝试使用OkHttp库与我的服务器(JSON通信)进行数据通信时,Picasso会抛出异常.

我使用以下罐子:okhttp-2.0.0-RC2,okio-1.0.0,picasso-2.2.0.当我添加这些罐子后运行我的项目时,它崩溃了以下内容:

06-12 11:13:15.824: E/dalvikvm(12105): Could not find class 'com.squareup.okhttp.HttpResponseCache', referenced from method com.squareup.picasso.OkHttpDownloader.<init>

我添加了okhttp只是为了使用以下方法:

public static String executeHttpGet(String urlStr) {
    Response response = null;
    String result = "";
    OkHttpClient client = new OkHttpClient();

    try {
        Request request = new Request.Builder().url(urlStr).build();

        response = client.newCall(request).execute();
        result = response.body().string();
    } catch (Exception ex) {

    }
    return result;
}

上面的代码没有任何问题.然而,使用Picasso库并且用于完美工作的代码开始抛出以下例外:

06-12 11:19:49.307: E/AndroidRuntime(13036): FATAL EXCEPTION: main
06-12 11:19:49.307: E/AndroidRuntime(13036): java.lang.NoClassDefFoundError: com.squareup.okhttp.HttpResponseCache

我的课程路径:

如果我删除okhttp-2.0.0-RC2,okio-1.0.0,Picasso线路工作.

为什么会这样？我如何一起使用两个库？

Answer 1

这个组合对我有用:

compile 'com.squareup.okhttp:okhttp:2.2.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'
compile 'com.squareup.picasso:picasso:2.4.0'

Answer 2

切换到毕加索2.3.2.你还需要okhttp-urlconnection-2.0.0-RC2.

Answer 3

//Below code for Picasso initializing once for the app
private Picasso picasso;
private OkHttpClient okHttpClient;

okHttpClient = new OkHttpClient();
picasso = new Picasso.Builder(this)
                .downloader(new OkHttpDownloader(okHttpClient))
                .build();

//Below code to retrieve the images whereever required on the app
picasso.with(context).load(imageUrl).placeholder(R.drawable.ic_launcher)

上面的代码对我来说很好.
