java - Android butterknife 多重分包

Question

我在我的应用程序中启用了 miltidex。 API 21+ 工作正常。Android api 16 原因:

java.lang.NoClassDefFoundError: ......AuthorizationController

如果我评论 BN 绑定(bind)，一切都会正常。启用 Multidex:multiDexEnabled true，编译 'com.android.support:multidex:1.0.1' 等。有什么办法让它发挥作用吗？

        android:theme="@style/AppTheme">

应用程序类:

public class MyApplication extends MultiDexApplication {...}

我尝试添加 multiDexKeepProguard，但 gradle 没有看到该方法，或者方法的声明已更改。

编辑2Bitterknife.bind() 中返回的 Butterknife Unbinder 会带来麻烦。有什么解决办法吗？

Have you included following? If you do not override the Application class, edit your manifest file to set android:name in the tag as follows:

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

if you do override the Application class but it's not possible to change the base class, then you can instead override the attachBaseContext() method and call MultiDex.install(this) to enable multidex:

public class MyApplication extends SomeOtherApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }
}
