emulator in commandline do not have always the property "dev.bootcomplete"

I'm using the emulator by command-line for our continuous integration server for our android application. With that approach we can test all Android Versions automatically. For the automatic installation and testing we are using the property "dev.bootcomplete", which is provided by the android emulator. Unfortunately we don't get it always. After a newly created emulator we are retrieving it, but when the emulator is several times used it do'nt throw it again... Has Anybody an idea?

Commands/ results:

[user@mob_ci ~]$ adb shell getprop dev.bootcomplete

error: device offl开发者_运维百科ine

I use hudson as a ci server, for hudson there is a android plugin which manages the emulator, it even creates the emulator for you if you want.

I would either check if "error: device offline" happens and then run

adb kill-server
adb start-server

or

shutdown the emulator after each build, as it's not necessary that the emulator runs all the time or do the tests run all the time ?

hope this helps :)
