其中解决问题的关键在于

E/AndroidRuntime( 2371): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.rockchip.ethernetsettings/com.rockchip.ethernetsettings.EthernetSettings}; have you declared this activity in your AndroidManifest.xml?

这个信息。寻找项目对应的AndroidManifest.xml，这个文件存在且正确。而且com.rockchip.ethernetsettings.EthernetSettings这个类的代码也在。

这 个错误信息可以理解为，android编译之后会将所有的AndroidManifest.xml组成一个表，在点击相应item的时候触发响应的过程是 通过item的name去这个表中找相应的类名，找到类名后，就调用这个类。而以上出错信息提示未找到这个类。怀疑这个类是否真的被编译进镜像了。查看 android.mk文件，

ifeq ($(strip $(USE_ETHERNET)),true)

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := eng

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_PACKAGE_NAME := EthernetSettings

LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)

endif

发现第一行的宏并没有被定义，在适当的地方添加即可。这里在device/seuic/tiger_mb/device.mk中添加如下：

# Ethernet +++

USE_ETHERNET := true

# Ethernet —

重新编译，问题解决。
