5.1的手机查看日志发现instant run是有变化的，安装的时候提示install apks，
$ adb install-multiple -r /Users/zhengyongxiang/Documents/gzqiaoqiao/app/build/intermediates/split-apk/XIAOMI_CHANNEL/debug/slices/slice_6.apk
/Users/zhengyongxiang/Documents/gzqiaoqiao/app/build/intermediates/split-apk/XIAOMI_CHANNEL/debug/slices/slice_5.apk

由此可见新的instant run是把apk拆成多个了，需要反编译看下各个拆分出来的apk里面是什么样的,通过把slice里面的包拖到studio里面可以发现，依赖包和真正的代码会被分别编译成apk文件，变化的时候直接运行代码包，而依赖包不再运行
$ adb install-multiple -r -p com.example.zhengyongxiang.pullhead /Users/zhengyongxiang/Downloads/tinker-dev/PullHead/

$ adb shell am startservice com.mofanbaby.qiaotalk/com.android.tools.fd.runtime.InstantRunService
$ adb shell am start -n "com.mofanbaby.qiaotalk/com.mofanbaby.qiaotalk.WelcomeActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
从日志看出新的instant run多了一个InstantRunService，具体变化需要查看源码
2.3的studio多了一个小闪电标志，直接运行，发现日志是
Hot swapped changes, activity restarted
而直接点击绿色的run按钮出来的日志是这样的
03/07 10:30:17: Launching app$ adb install-multiple -r -p ...
$ adb shell am startservice ...com.android.tools.fd.runtime.InstantRunService
$ adb shell am start -n ...
Connected to process 5268 on device huawei-eva_tl00-B2T5T16620000622
由此可见小闪电对应的是之前的hot swap,而run按钮对应的是cold swap,有修改的时候先点小闪电，不生效再点绿色的那个run按钮
未完待续...
