我正在发布我的 apk。在 Debug模式下，我没有错误。 当我使用 Proguard 签署我的 apk 时，我的应用程序一直运行到第四个屏幕，在那里我必须处理一个实现 Parcelable 的值对象类

我已经看过好几个帖子了，但是没有一个能解决我的问题
Proguard causing RuntimeException (Unmarshalling unknown type code) in Parcelable class
我可以将 parcelable 更改为 json 字符串，但我还有其他 parcelables 对象，我担心将来会遇到其他类似问题。
任何帮助将不胜感激!
最佳答案
当 Android 尝试从通过 IPC 传递的 Bundle 中读取任何值(通过 startActivity、sendBroadcast 等发送)时，它会解包整个 Bundle 中的所有内容。如您所见，如果 Android 遇到任何不在您的类路径中的类，它就会抛出 java.lang.ClassNotFoundException。
这里有一些尝试，您可能需要其中的一个或多个:
在您的 proguard.pro 文件中包含以下内容，以保留 Parcelables 的 CREATOR，Android 通过反射引用它(我认为 Google 会自动将此规则添加到每个应用程序，但有时它似乎没有取决于您的构建系统):
# keep CREATOR for referenced parcelables since it is accessed via reflection
-keepclassmembers class * implements android.os.Parcelable {
static ** CREATOR;
}
在从 Bundle 中获取任何东西之前添加类加载器。这假设此代码是从您的 APK 中的类运行的(因此与 extra 中的自定义 Parcelable 类共享相同的类加载器)或者您可以传递 Context 并使用 Context #getClassLoader() 如果您在静态方法中:
extras.setClassLoader(getClass().getClassLoader());
如果您的 Bundle 中有您实际上没有使用但在您的类路径中的 Parceables，那么您可以使用此规则保留所有 Parceables:
# Keep all known parcelables
-keep public class * implements android.os.Parcelable
最后，如果您收到一个带有 Parcelable 的 Bundle，而应用程序在构建时不知道该类，则 Bundle 是很可能中毒，你根本无法使用它。这是让您不喜欢的其他 Android 应用程序崩溃的好方法!您能做的最好的事情就是 try catch 您第一次访问 Bundle 的代码块，以避免应用程序崩溃。
try {
Bundle extras = getIntent().getExtras();
if (extras != null) {
// Trigger unparcel
extras.size();
}
} catch (BadParcelableException e) {
Log.w(TAG, "Got poison Bundle or programmer needs to fix proguard/classloader", e);
}
关于android - Proguard 和 Object extends Parcelable - 解码时找不到类，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25770049/
