本文整理了Java中android.os.Parcel.marshall()方法的一些代码示例，展示了Parcel.marshall()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Parcel.marshall()方法的具体详情如下：
包路径：android.os.Parcel
类名称：Parcel
方法名：marshall

Parcel.marshall介绍

[英]Returns the raw bytes of the parcel.

The data you retrieve here must not be placed in any kind of persistent storage (on local disk, across a network, etc). For that, you should use standard serialization or another kind of general serialization mechanism. The Parcel marshalled representation is highly optimized for local IPC, and as such does not attempt to maintain compatibility with data created in different versions of the platform.
[中]返回包裹的原始字节。
您在此处检索的数据不得放在任何类型的永久性存储中（在本地磁盘上、通过网络等）。为此，应该使用标准序列化或其他类型的通用序列化机制。包裹编组表示法针对本地IPC进行了高度优化，因此不会试图保持与在不同版本平台中创建的数据的兼容性。
