如何修复Android中偏移YYY的Unmarshalling未知类型代码XXX?
作者:互联网
由于Unmarshalling异常,我正在恢复应用程序崩溃.我检查了所有Serializables都没有参数的构造函数,甚至使用ObjectStream检查了所有可序列化(保存到文件并从文件加载).我如何理解导致异常的parcelable偏移的实际类类型:

保存的数据包括Bundles和Serializables,所有这些都很好看.
我打算做下一个:
try {
// unmarshalling
} catch (Throwable t) {
// look offset
}
我如何理解Parcelable偏移的实际类型?
解决方法:
写入和读取parcelables有一些规则.
1-注意类型不匹配.如果你写int,不要试着读长等.
2-注意写入和读取的顺序.在读取和写入时,对象必须处于相同的排序顺序.
这两个都可能导致“解组未知类型代码”.
