如何等待Android虚拟设备完成启动

Question

我有这个启动脚本

#!/bin/bash

echo "starting devices"

emulator -avd emulator-5554 -wipe-data &
emulator -avd emulator-5556 -wipe-data &
emulator -avd emulator-5558 -wipe-data &
emulator -avd emulator-5560 -wipe-data &

echo "waiting for devices"
adb wait-for-any-device
echo "devices waited for complete"

devices waited for complete在设备开始引导后打印，但在设备完成引导后不打印。

是否有类似的命令等待设备完成启动？
