java.lang.NoClassDefFoundError：okhttp3.OkHttpClient $ Builder [英] java.lang.NoClassDefFoundError: okhttp3.OkHttpClient$Builder
问题描述
在我的项目中，我使用OkHttp（版本2.5.0）作为我的网络请求库。但是几天前，我尝试将Retrofit2作为我的应用程序的网络请求库的一部分，如你所知，新的Retrofit2库依赖于OkHttp（版本3.2.0）。所以这里出现的问题是当我的应用程序运行在Android手机上的android android 5.0下的版本总是会导致崩溃（较大版本运行良好并且不会导致崩溃），崩溃堆栈信息显示如下：
In my project, I have used OkHttp(version 2.5.0) as my network request library. But few days ago, I tried Retrofit2 as part of my app's network request library, as you know, the new Retrofit2 library dependence on OkHttp(version 3.2.0).So here comes the problem that when my app runs on android phone whose android version under android 5.0 always causes crash(larger version works well and causes no crash), the crash stack information shows as below:

从堆栈跟踪中，我猜OkHttp（版本3.2.0）与OkHttp（版本2.5.0）有一些冲突。下面我将给出我的外部库配置：
From the stack trace, I guess that OkHttp(version 3.2.0) has some conflicts with OkHttp(version 2.5.0). Below I will give my external library configuration:
compile 'com.squareup.okhttp:okhttp:2.5.0'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:retrofit:2.0.1'
compile 'com.squareup.retrofit2:converter-gson:2.0.1'
<希望任何知道这个问题的人都可以帮个忙！非常感谢！
Hope anyone who knows the problem can give me a favor! Great thanks!
更新1：
这是我的 ServiceGenerator.java ：
package com.comingx.athit.client;
import com.comingx.athit.model.Constants;
import com.comingx.athit.model.modelmanager.ModelManagerSingleton;
import java.io.IOException;
import okhttp3.Interceptor;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class ServiceGenerator {
private static OkHttpClient httpClient = new OkHttpClient.Builder().addInterceptor(
new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request()
.newBuilder().addHeader("Cookie", ModelManagerSingleton.getNative_cookie()).build();
return chain.proceed(request);
}
}
).build();
private static Retrofit.Builder builder =
new Retrofit.Builder()
.baseUrl(Constants.V3.API_PREFIX)
.addConverterFactory(GsonConverterFactory.create());
public static <T> T createService(Class<T> serviceClass) {
Retrofit retrofit = builder.client(httpClient).build();
return retrofit.create(serviceClass);
}
}
推荐答案
是，最后我找到问题并解决它。我在这里查看了类似的问题，并发现可能 64K方法可能会导致问题，所以我来到官方网站
查看使用超过64K方法构建应用。
现在你应该在build.gradle文件中编译multidex库：
Yes, finally I find the problem and solve it. I viewed a similar problem here and find that maybe the 64K Methods could cause the problem, so I came to official site to view Building Apps with Over 64K Methods. Now you should compile the multidex library in your build.gradle file:
compile 'com.android.support:multidex:1.0.1'
别忘了配置你的defaultConfig：
And don't forget to config your defaultConfig:
android {
defaultConfig {
multiDexEnabled true
}
}
最后你可以写一个 BaseApplication 扩展到 Application ，重写 attachBaseContext（Context base）方法，如下所示：
And finally you can write a BaseApplication extends to Application, over write the attachBaseContext(Context base) method as follows:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
不要忘记将其添加到AndroidManifest.xml文件中：
Don't forget to add this to your AndroidManifest.xml file:
<application
android:name=".BaseApplication"
android:allowBackup="true">
</application>
