本文整理了Java中android.util.Base64.encode()方法的一些代码示例，展示了Base64.encode()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。Base64.encode()方法的具体详情如下：
包路径：android.util.Base64
类名称：Base64
方法名：encode

Base64.encode介绍

[英]Base64-encode the given data and return a newly allocated byte[] with the result.
[中]Base64对给定数据进行编码，并返回新分配的字节[]和结果。

代码示例
