[android-porting] Re: Calling a class in a .jar library from a system level service

[Drunczyk]

I fixed that error by adding the extender.jar library 
to PRODUCT_SYSTEM_SERVER_JARS in the product .mk file.

Now I'm trying to understand the build problem: services.jar references my 
prebuilt static java library newservice, newservice uses prebuilt 
extender.jar. If I do a full product build, newservice gets compiled into 
services.jar, but extender.jar isn't installed into /system/frameworks and 
thus isn't found in the final FW image. Adding LOCAL_REQUIRED_MODULES 
doesn't seem to help.

I suspect the problem here is the the build doesn't think extender.jar is 
part of the built product.

Android.mk:
==
$ LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := newservice
LOCAL_MODULE_TAGS := eng optional
LOCAL_SRC_FILES := javalib.jar
LOCAL_REQUIRED_MODULES := extender
LOCAL_MODULE_CLASS := JAVA_LIBRARIES
LOCAL_MODULE_SUFFIX := $(COMMON_JAVA_PACKAGE_SUFFIX)
include $(BUILD_PREBUILT)

include $(CLEAR_VARS)
LOCAL_MODULE := extender
LOCAL_MODULE_TAGS := eng optional
LOCAL_SRC_FILES := extender.jar
LOCAL_MODULE_CLASS := JAVA_LIBRARIES
LOCAL_MODULE_SUFFIX := $(COMMON_JAVA_PACKAGE_SUFFIX)
include $(BUILD_PREBUILT)

==

[android-porting] Calling a class in a .jar library from a system level service

[Drunczyk]

Hello,

I have a service added into the framework with the other standard services 
(services.jar). I want the service to be able to call some methods in a 
.jar library (extender.jar). When the platform builds, everything is fine, 
references to the library get resolved correctly, the library gets into 
/system/framework, but when the service tries to call a method in the 
library, it gets Error: 0xffe0 "Broken pipe" and logcat shows:

Is there a way to fix it?

Thanks
