命令行启动模拟器　adb命令不执行或很久才执行的问题

step1：打印错误信息

./emulator -avd 24darm -noaudio -no-accel -verbose  -gpu off -no-window
//-verbose//打印启动详细信息

我的报错是一直重复的　　Adb connected, start proxing data　　 Adb closed by host　　Adb closed by guest

step2：我的处理方式

经过各种查资料，查网页。没找到类似的问题，但是发现多等一会　就可以正确执行adb的命令了

emulator: _hwFingerprint_connect: connect finger print listen is called

emulator: got message from guest system fingerprint HAL////一直到出现这个log后

因为也看不到界面　　log里面也没有成功的提示，所以猜测启动的速度慢　直到打印完才模拟器才完成启动。中途的adb命令有的会被执行　，有的就一直被挂着。可能和adb与模拟器的连接　　因为启动未完成，所以连接一直被关闭有关系。
