编译完android系统后，在/out/target/product/filename目录中生成了img文件（system.img userdata.img ramdisk.img uImage）想用emulator启动编译好的内核，
于是输入命令：
emulator -image system.img -data userdata.img -ramdisk ramdisk.img
这时出现了以下警告：
emulator: WARNING: Please note that -image is obsolete and that -system is now used to point
to the system image. Next time, try using '-sysdir <path> -system <file>' instead.
emulator: WARNING: system partition size adjusted to match image file (200 MB > 66 MB)
emulator: WARNING: Unable to create sensors port: Connection refused
emulator: emulator window was out of view and was recentered
弹出的模拟器一直黑屏，启动没成功，开始以为是WARNING: system partition size adjusted to match image file (200 MB > 66 MB)这个问题产生的
于是又输入以下命令：
emulator -image system.img -data userdata.img -ramdisk ramdisk.img -partition-size 210
这时出现的警告又变了：
emulator: WARNING: Please note that -image is obsolete and that -system is now used to point
to the system image. Next time, try using '-sysdir <path> -system <file>' instead.
emulator: WARNING: Unable to create sensors port: Connection refused
弹出的模拟器还是一直黑屏
怀疑是不是因为没加上内核的关系，于是输入以下命令：
emulator -image system.img -data userdata.img -ramdisk ramdisk.img -partition-size 210 -kernel uImage
感觉这时应该能启动了吧，却又报错：
emulator: WARNING: Please note that -image is obsolete and that -system is now used to point
to the system image. Next time, try using '-sysdir <path> -system <file>' instead.
emulator: WARNING: Unable to create sensors port: Connection refused

已放弃
这时模拟器启动之后又快速退出，连黑屏都省了直接异常退出！！！！！！！
该怎么解决这个问题呢？？？？？
------解决方案--------------------
4.0代码 make 之后 直接emulator
------解决方案--------------------
几次提示你的try using '-sysdir <path> -system <file>' instead.
你的这个system.img能不能改一下
