<category android:name="com.android.settings.SHORTCUT" />
</intent-filter>
</activity>
三、接下来要增加Ethernet的状态栏图标
3.1.复制源路径frameworks/base/packages/SystemUI/res/drawable-hdpi/connect_creating.png到目标路径对应目录下
3.2.复制源路径frameworks/base/packages/SystemUI/res/drawable-hdpi/connect_established.png到目标路径对应目录下
3.3.复制源路径frameworks/base/packages/SystemUI/res/drawable-hdpi/connect_no.png到目标路径对应目录下
3.4.复制源路径frameworks/base/packages/SystemUI/res/drawable-mdpi/connect_creating.png到目标路径对应目录下
3.5.复制源路径frameworks/base/packages/SystemUI/res/drawable-mdpi/connect_established.png到目标路径对应目录下
3.6.复制源路径frameworks/base/packages/SystemUI/res/drawable-mdpi/connect_no.png到目标路径对应目录下
四、修改目标路径文件build/core/pathmap.mk
vpn \+ethernet \
keystore \
最后记得修改init.rc，在最后增加DHCP服务
service dhcpcd_eth0 /system/bin/dhcpcd -ABKL
disabled
oneshot
service iprenew_eth0 /system/bin/dhcpcd -n
disabled
oneshot
