java.lang.NoClassDefFoundError: okhttp3.OkHttpClient$Builder
提问by wizChen
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:
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 作为我的应用程序网络请求库的一部分，如您所知，新的 Retrofit2 库依赖于 OkHttp（版本 3.2.0）。所以当我的应用程序在其 android android 5.0下的版本老是崩溃（大版本正常，不崩溃），崩溃堆栈信息如下：

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:
从堆栈跟踪来看，我猜 OkHttp(version 3.2.0) 与 OkHttp(version 2.5.0) 有一些冲突。下面我将给出我的外部库配置：
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'
Hope anyone who knows the problem can give me a favor! Great thanks!
希望知道问题的人能给我一个帮助！万分谢意！
Update 1:Here is my ServiceGenerator.java:
更新 1：这是我的ServiceGenerator.java：

}

Yes, finally I find the problem and solve it. I viewed a similar problem hereand find that maybe the 64K Methodscould cause the problem, so I came to official siteto view Building Apps with Over 64K Methods. Now you should compile the multidex library in your build.gradle file:
是的，最后我找到了问题并解决了它。我在这里查看了一个类似的问题 ，发现可能是64K Methods可能导致问题，所以我来到官方网站查看Building Apps with Over 64K Methods。现在您应该在 build.gradle 文件中编译 multidex 库：
compile 'com.android.support:multidex:1.0.1'
And don't forget to config your defaultConfig:
并且不要忘记配置您的 defaultConfig：
android {
defaultConfig {
multiDexEnabled true
}
}
And finally you can write a BaseApplicationextends to Application, over write the attachBaseContext(Context base)method as follows:
最后，您可以编写一个BaseApplication扩展到Application，重写attachBaseContext(Context base)方法，如下所示：
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
Don't forget to add this to your AndroidManifest.xml file:
不要忘记将其添加到您的 AndroidManifest.xml 文件中：
<application
android:name=".BaseApplication"
android:allowBackup="true">
</application>
