有一种方法可以为您生成它。我写了一篇文章，展示了如何使用它 更新（2014年10月31日）：
Gradle插件v0.14.0现在可以自动完成。看看我的答案 更新（2017年4月24日）：
解释了如果不能自动选择所有正确的类，如何使用gradle选项选择特定类。我终于解决了这个问题！原因不在

ErrorHandlerAppWrapperErrorHandlerAppWrapper无论如何，解决方案不是通过
AppWrapperErrorHandler如果有人因为在棒棒糖前的设备上找不到他们的应用程序类而来到这里，但应用程序在棒棒糖上运行良好，那么这似乎是Jack和Multidex的一个已知问题 参考：
参考：我也遇到了这种问题。我的解决方案是： 在我的build.gradle文件中，依赖项中有多个
compile'com.android.support:multidex:1.0.0'dependencies {
compile 'com.android.support:multidex:1.0.0'
compile 'com.android.support:multidex:1.0.0'
// other dependencies ........
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
// other dependencies ........
}
NoClassDefFound可用于任何未加载到API早于Lollipop且启用了multidex的设备上的任意类。如果您正确设置了ProGuard，那么您就可以轻松地使用它，而不必承担多索引开销，从而使您的应用程序在发布版本中启动缓慢，尤其是在旧设备上。然而，当您在调试模式下开发应用程序时，您不希望ProGuard减慢您的速度。如果尝试在禁用ProGuard的情况下启动调试生成，您将开始出现生成错误，如
com.android.dex.DexIndexOverflowException:无法将新索引72118合并到非巨型指令中
因此，您真正想要的是仅在发布版本上启用ProGuard和禁用multidex，而在禁用ProGuard和启用multidex的情况下，调试版本应该相反。当然，您还必须挑剔，使用较少的依赖项，因为您的发布版本将受到64K限制
这需要将build.gradle设置为具有buildTypes
configs，并仅为调试而编译multidex支持库依赖项
应用程序子类还必须设置为派生自不同的子类，具体取决于您是否处于multidex模式。这可以使用gradlemanifest合并原则来实现，方法是为调试构建定义覆盖清单，然后以不同的方式指定应用程序类
以下是相关的应用程序模块build.gradle：
android {
...
buildTypes {
debug {
minifyEnabled false //Disabled Proguard
multiDexEnabled true // Enabling multi-dex support.
}
release {
minifyEnabled true //Enabled Proguard
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
multiDexEnabled false // Disable multi-dex support.
}
}
dependencies {
debugCompile 'com.android.support:multidex:1.0.1' //debugCompile makes it included only for debug builds
...
}
}
如果不使用应用程序子类，则只需指定应用程序子类的名称android.support.multidex.MultiDexApplication
，如中所述，但您只希望在调试构建时这样做
为此，必须在调试和发布变体文件夹层次结构中指定覆盖文件，如下所示：
src
- main
- AndroidManifest.xml
- java/com/yourcompany/MyApplication.java (extends from BaseApplication)
- release
- java/com/yourcompany/BaseApplication.java (extends from Application)
- debug
- AndroidManifest.xml
- java/com/yourcompany/BaseApplication.java (extends from MultiDexApplication)
是的，您可以在主模块文件夹旁边创建debug
和release
文件夹。在中添加以下文件：
debug/AndroidManifest.xml
debug/java/com/yourcompany/BaseApplication.java
main/java/com/yourcompany/MyApplication.java
通过这种方式，您可以在基类不同的情况下将应用程序的功能添加到MyApplication.java
。如果一切正常，但出现此错误
尝试禁用即时跑步
当我禁用它时，所有的类都被正确加载。我尝试了很多解决方案，但没有人为我工作。最后，我发现：
public class MyApplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
这是解决我问题的唯一办法。可能有人遇到了同样的问题，这可能会有所帮助：）在gradle中添加以下依赖项
implementation 'com.android.support:multidex:1.0.3'
在app-levelbuild.gradle中，添加如下参数
defaultConfig {
multiDexEnabled = true
}
在应用程序类中，在下面的行中添加
MultiDex.install(this);
谢谢，我试试你的剧本。但是AppWrapper已经在主索引列表文件中（我将其添加到问题中）。不过，它似乎被忽略了。您的AppWrapper实现了Reformation.ErrorHandler接口，该接口也应该放在主索引中。Dalvik无法解析接口，因此无法加载AppWrapper类。@AlexLipov是的，就是这样，我绊倒了
public class MyApplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
implementation 'com.android.support:multidex:1.0.3'
defaultConfig {
multiDexEnabled = true
}
MultiDex.install(this);
