本项目使用Tinker进行热修复的过程；
1.运行项目；
2.此时将编译生产在bakApk包下的文件替换gradle中的对应版本；
ext {
tinkerEnabled = true
// 基础版本apk
tinkerOldApkPath = "${bakPath}/mytinker-debug-20170629-16-41-16.apk"
//proguard mapping file to build patch apk
tinkerApplyMappingPath = "${bakPath}/"
// 与基础版本一起生成的R.text文件
tinkerApplyResourcePath = "${bakPath}/mytinker-debug-20170629-16-41-16-R.txt"
//only use for build all flavor, if not, just ignore this field
tinkerBuildFlavorDirectory = "${bakPath}/"
}
3.运行脚本，得到patch_signed_7zip.apk
4.根据代码中的路径，patch_signed_7zip.apk放在手机中对应路径
String patch = Environment.getExternalStorageDirectory()+ File.separator+"tinker" + "/patch_signed_7zip.apk" ;
5.最后执行加载补丁
