java - MultiDex NoClassDefFounderror

标签 java android

我已将我的应用程序转换为 MultiDex 以承受 64k dex 限制。现在看起来像这样:

public class App extends MultiDexApplication {

private AppWrapper instance;

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

@Override
public void onCreate() {
    super.onCreate();

    if (instance == null) {
        instance = new AppWrapper(this);
    }
}
}

我已将所有常用逻辑从 App 提取到 AppWidget 以使 MultiDex 工作。它在其他队友的电脑上运行正常。但不是和我在一起。它在应用程序创建时不断抛出 java.lang.NoClassDefFoundError:

我有相同的 Android Studio、gradle、sdk、jdk 版本，相同的代码。我什至尝试格式化硬盘并重新安装操作系统以确保环境相同。这个奇怪问题的原因可能是什么？

这是我的 build.gradle:

更新。我的 multidex.keep 文件:

最佳答案

您的 AppWrapper 类无法加载，因为 retrofit.ErrorHandler 接口(interface)未包含在主 dex 文件中。

如何计算要放入 main-dex-list 文件中的类？
有一个script可以为您生成它。我写了一个 blogpost这显示了如何使用它。

更新(2014 年 10 月 31 日):
Gradle 插件 v0.14.0 现在自动完成。看我的回答here .

更新(2017 年 4 月 24 日):
developer guide解释了如果不能自动选择所有正确的类，如何使用 gradle 选项选择特定的类。
