could not find method namespace() for arguments [com.benjaminabel.vibration]

  有时候需要把代码制作成jar包放入到项目中，如果只是一个普通的java文件导入系统都是没有问题的，但是很有可能需要将service导出jar包到，由系统启动。 

 
 1.通常只需要修改SystemService.java，比如jar包为AutoService_v0.1.jar，把该文件拷贝到framework/base/services/java/目录下。 

 
 2.修改framework/base/services/java目录下的Android.mk文件，这样才会编译到系统，通常都是编译到services.java里面，这不是绝对的。 

 
 LOCAL_PATH:= $(call my-dir) 

 
 include $(CLEAR_VARS) 

 
 LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := AutoService:AutoService_v0.1.jar 

 
 include $(BUILD_MULTI_PREBUILT) 

 
 # the library 

 
 # ============================================================ 

 
 include $(CLEAR_VARS) 

 
 LOCAL_SRC_FILES := \ 

 
             $(call all-subdir-java-files) \ 

 
         com/android/server/EventLogTags.logtags \ 

 
         com/android/server/am/EventLogTags.logtags 

 
 LOCAL_SRC_FILES += $(call all-Iaidl-files-under,com) 

 
 LOCAL_MODULE:= services 

 
 LOCAL_JAVA_LIBRARIES := android.policy conscrypt telephony-common  
 AutoService 

 
 include $(BUILD_JAVA_LIBRARY) 

 
 include $(BUILD_DROIDDOC) 

 
 3.启动autoservice，这时需要修改SystemService.java，修改如下。 

 
 4.最后是编译，我们可以用mmm方式进行编译，这样会节省编译时间。 

  mmm framework/base/services/java 

    mmm编译生成services.jar文件，把该文件push到机器的/system/framework目录下，重启机器。也许你会有很大的惊喜，也许会让你失望。不过没关系，办法总是有的。 

 
 5.下面来看看错误信息 

 
 D/SensorService( 2614): nuSensorService thread starting... 

 
 I/dalvikvm( 2614): Could not find method com.semisky.autoservice.services.AutoService.getInstance, referenced from method com.android.server.ServerThread.initAndLoop 

 
 W/dalvikvm( 2614): VFY: unable to resolve static method 14434: Lcom/semisky/autoservice/services/AutoService;.getInstance ()Lcom/semisky/autoservice/services/AutoService;

...

 W/SystemServer( 2614): ***********************************************

 F/SystemServer( 2614):     at java.lang.reflect.Method.invokeNative(Native Method) 

 
 F/SystemServer( 2614):     at java.lang.reflect.Method.invoke(Method.java:515)

 F/SystemServer( 2614):     at dalvik.system.NativeStart.main(Native Method) 

  上面的错误信息让人头痛，从字面意思来看说是找不到 
 com.semisky.autoservice.services.AutoService.getInstance方法，其实AutoService里面是有getInstance方法的。 

 
 6.解决办法 

  将Android.mk文件改成如下，重新编译push到机器上，解决此问题。 

 
 LOCAL_PATH:= $(call my-dir) 

 
 include $(CLEAR_VARS) 

 
 LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := AutoService:AutoService_v0.1.jar 

 
 include $(BUILD_MULTI_PREBUILT) 

 
 # the library 

 
 # ============================================================ 

 
 include $(CLEAR_VARS) 

 
 LOCAL_SRC_FILES := \ 

 
             $(call all-subdir-java-files) \ 

 
         com/android/server/EventLogTags.logtags \ 

 
         com/android/server/am/EventLogTags.logtags 

 
 LOCAL_SRC_FILES += $(call all-Iaidl-files-under,com) 

 
 LOCAL_MODULE:= services 

 
 LOCAL_JAVA_LIBRARIES := android.policy conscrypt telephony-common 

 
 LOCAL_STATIC_JAVA_LIBRARIES := AutoService 

 
 include $(BUILD_JAVA_LIBRARY) 

 
 include $(BUILD_DROIDDOC)
