我正在使用 okhttp3 和 glide，所以我也添加了集成部分。

compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.github.bumptech.glide:glide:3.6.1'
compile 'com.github.bumptech.glide:okhttp-integration:1.4.0@aar'

我什至使用

compile 'com.android.support:multidex:1.0.1'

并将其添加到应用程序类

 @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(base);
    }

这是完整的堆栈跟踪 -

这是构建的配置

productFlavors {
        // Define separate dev and prod product flavors.
        dev {
            // dev utilizes minSDKVersion = 21 to allow the Android gradle plugin
            // to pre-dex each module and produce an APK that can be tested on
            // Android Lollipop without time consuming dex merging processes.
            minSdkVersion 21
        }
        prod {
            // The actual minSdkVersion for the application.
            minSdkVersion 15
        }
    }

我无法弄清楚 dex 进程有什么问题。

编辑

如果我简单地从 build.gradle 中删除集成部分，一切都会很好

compile 'com.github.bumptech.glide:okhttp-integration:1.4.0@aar'

最佳答案

除非方法太多，否则不需要 multidex。

确定您使用的是 okhttp (v2) 还是 okhttp3 并相应地更新您的代码:

compile 'com.github.bumptech.glide:okhttp-integration:1.4.0@aar'
compile 'com.squareup.okhttp:okhttp:2.7.5'

或

compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar'
compile 'com.squareup.okhttp3:okhttp:3.2.0'

阅读https://github.com/bumptech/glide/wiki/Integration-Libraries了解更多详情。
