Now I already built a third party jar called telephony_DA. And I already can use this telephony_DA library in application level. (modication on AndroidManifest.xml and add permission into /etc/permissions)

My problem is that I wrote a new service called TelephonyRegistry_DA.java in
"com.android.server" package and used the classes from telephony_DA library. After noting the telephony_DA library in Android.mk, I can built services library sucessfully. But in run time it appearred crash with the reason of 

"java.lang.NoClassDefFoundError: com.android.server.TelephonyRegistry_DA"

I tried to figure out the issue then I found something. Once I remove the classes from telephony_DA library in TelephonyRegistry_DA.java then in run time there is no issue on creating and adding service from TelephonyRegistry_DA.java. It seems that systemserver didn't know the link with telephony_DA library.

So how do I add a thirdparty jar into systemserver.java?

Thanks.

In application level, you can inidcat 3rd party library from manifest.xml. But in services from system server you should add 3rd party libary into default linking path. so please modify (ex: telephony_DA.jar) init.rc as below.

export BOOTCLASSPATH /system/framework/core.jar:/system/framework/core-junit.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar:/system/framework/apache-xml.jar:/system/framework/filterfw.jar:/system/framework/telephony_DA.jar
