我有一个项目，我在其中启用了 multidex 以避免 65k 限制 和 productFlavors(dev API 21 和 prod API 19)用于定制。 在 API 21 上构建我的项目，即开发风格是成功的，但在 API 19 上，即 prod 风格上，它不断给我在应用程序任务 shr​​ink{component}MultiDexComponents 中的异常

完整的错误日志:

:app:shrinkProdDebugMultiDexComponents FAILED

最佳答案

对 Android 5.0 及更高版本的 Multidex 支持

Android 5.0 and higher uses a runtime called ART which natively supports loading multiple dex files from application APK files. ART performs pre-compilation at application install time which scans for classes(..N).dex files and compiles them into a single .oat file for execution by the Android device. For more information on the Android 5.0 runtime, see Introducing ART.

这就是您的应用在 API 级别 21 上运行良好的原因。

Android 5.0 之前的 Multidex 支持

Versions of the platform prior to Android 5.0 use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK. In order to get around this limitation, you can use the multidex support library, which becomes part of the primary DEX file of your app and then manages access to the additional DEX files and the code they contain.

所以，首先确保您导入了正确的依赖项，看起来您已经导入了。

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

在您的 list 中，将 multidex 支持库中的 MultiDexApplication 类添加到应用程序元素。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

或者，如果您的应用扩展了 Application 类，您可以覆盖 attachBaseContext() 方法并调用 MultiDex.install(this) 以启用 multidex。

public void onCreate(Bundle arguments) {
    MultiDex.install(getTargetContext());
    super.onCreate(arguments);
    ...
}

希望对您有所帮助。
