Android(安卓)dumpsys input详解

（用华为P30带你看安卓）
简介：华为P30,Android 9.0(API 28)
如果你在从事安卓的开发，如果你苦于看不懂android 的输入逻辑，如果你想找到更好Android 调试工具，那么强烈建议你看完本文。如果你那么做了，你会了解dumpsys input ,你会了解 input事件的派发逻辑，你会对Android 更感兴趣；

按键字符映射文件是由键盘类型声明和一组按键声明组成的纯文本文件。
https://source.android.google.cn/devices/input/key-character-map-files?hl=zh-cn
将识别以下键盘类型：
NUMERIC：数字（12 键）键盘。
PREDICTIVE：一种具有所有字母的键盘，但每个键有多个字母。
ALPHA：一种具有所有字母的键盘，并且可能还带有一些数字。
FULL：一种 PC 式全键盘。
SPECIAL_FUNCTION：一种仅用于执行系统控制功能（而非打字）的键盘。
==>Generic.kcm 和 Virtual.kcm 按键字符映射都是 FULL 键盘。
sha1 - 生成sha1散列值生成唯一标识来标识设备
#include
int SHA1_Init（SHA_CTX * c）;
int SHA1_Update（SHA_CTX * c， const void * data，unsigned long len）;
int SHA1_Final（unsigned char * md，SHA_CTX * c）;
KeyLayoutFile条目中看到加载的按键映射文件，都是根据厂商ID和产品ID匹配对应文件的，例如
vendor为0x3697，product 为0x0001，那么对应的配置文件为/system/usr/keylayout/Vendor_3697_Product_0001.kl (注：华为手机并未使用其他外设input)
