Hi Kishore,

It means your SystemServer is crashing during its initialization, most likely due to your custom system service.

Please check your logcat, it will hopefully give you more information.

Gary

You did not include more details on which service you're adding but I would suggest maybe looking at the Android Developer Forums on the specifics of the kind of service you're adding. You're also welcome to add it here so other community users may contribute.

Hello Gary,

   I followed the following Blog to add new custom System Service to the AOSP (Lollipop 5.0.2).

shridutt kothari's blog: Adding New System Service in Android

Android-Adding SystemService - Texas Instruments Wiki

After adding new System Service , we have to add the Service to  /external/sepolicy/service_contexts to avoid SELinux policy denies

refer the below post
