导航库 inflator 为数据抛出 ClassNotFoundException class
Navigation Library inflator throws ClassNotFoundException for data class
-
android
-
kotlin
-
kotlin-android-extensions
-
android-architecture-components
-
android-architecture-navigation
在导航库版本 alpha09+（使用 alpha11）中，我的一个数据 classes 遇到了 ClassNotFoundException，我在导航图中将其定义为 argType。
app:argType="com.package.app.data.model.user.User.Full"
这个class确实存在。降级回 alpha08 时，问题似乎没有发生。
这是完整的堆栈跟踪：

我已将导航库组件从 alpha08 更新到 alpha11。当他们发布 alpha09 时，我也更新并遇到了同样的问题，并认为这是一个错误，所以我等待。现在，问题仍然存在，我似乎无法弄清楚哪里出错了。
我已经禁用了 ProGuard 进行调试，并启用了 Multidex 以查看是否有帮助。
debug {
minifyEnabled false
useProguard false
versionNameSuffix '-DEBUG'
applicationIdSuffix '.debug'
}
class 也已添加到 proguard-rules 中，看看是否可行。
-keep class com.package.app.data.model.** { *; }
据我所知，这应该行得通吗？ Android Studio 也像这样为我生成 XML。
提前致谢。
我遇到了同样的问题，我的 argType 是 class，即片段的 Subclass。我将 class 从片段中移出，问题已解决
毕竟，这是 Android Studio 中的一个已知错误。
自 1.0.0-alpha09 发布以来，他们处理内部 classes 的方式发生了一些变化。
如果 parcelable 是内部 class，它必须这样写：
com.domain.app.User$Full 其中 Full 是 parcelized 对象。
如果您想阅读更多相关信息，请在 Google 的问题跟踪器上查看此答案：https://issuetracker.google.com/u/2/issues/123614632#comment4
刚遇到与此问题类似的问题，我意识到我没有设置任何 proguard 规则。以下是可能有用的其他信息。
导航组件版本2.2.0-rc02中找到以下代码。
// NavType.java
try {
String className;
if (type.startsWith(".") && packageName != null) {
className = packageName + type;
} else {
className = type;
}
if (type.endsWith("[]")) {
className = className.substring(0, className.length() - 2);
Class<?> clazz = Class.forName(className);
if (Parcelable.class.isAssignableFrom(clazz)) {
return new ParcelableArrayType(clazz);
} else if (Serializable.class.isAssignableFrom(clazz)) {
return new SerializableArrayType(clazz);
}
} else {
Class<?> clazz = Class.forName(className);
if (Parcelable.class.isAssignableFrom(clazz)) {
return new ParcelableType(clazz);
} else if (Enum.class.isAssignableFrom(clazz)) {
return new EnumType(clazz);
} else if (Serializable.class.isAssignableFrom(clazz)) {
return new SerializableType(clazz);
}
}
throw new IllegalArgumentException(className + " is not Serializable or "
+ "Parcelable.");
} catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
您可以看到它使用 Class.forName(String) 方法查找 类。所以保留他们的名字就足够了。
# Instead of -keep
-keepnames class com.package.app.data.model.** { *; }
并且如果提供了 packageName，您可以从 argType 属性的值中省略包名称，但遗憾的是，如果您根据构建变体使用某些应用程序 ID 后缀，它将不起作用。 （所以不要从 argType 中省略包名称）
