Android Debug Bridge | Android Developers
Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or higher.
adb 可以让电脑通过usb 连接 android 手机进行调试Debug，在满足上述条件下，必须进入手机设置选中USB DEBUG。

CharsetDetector (ICU4J 51.1)
字符集分析发现，文件编码发现
CharsetDetector provides a facility for detecting the charset or encoding of character data in an unknown format. The input data can either be from an input stream or an array of bytes. The result of the detection operation is a list of possibly matching charsets, or, for simple use, you can just ask for a Java Reader that will will work over the input data.
Character set detection is at best an imprecise operation. The detection process will attempt to identify the charset that best matches the characteristics of the byte data, but the process is partly statistical in nature, and the results can not be guaranteed to always be correct.
For best accuracy in charset detection, the input data should be primarily in a single language, and a minimum of a few hundred bytes worth of plain text in the language are needed. The detection process will attempt to ignore html or xml style markup that could otherwise obscure the content.
