<b>Step 3：<br></b>
<br>
Decompress "realtek_wifi_SDK_for_android_KK_4.4_20140117.tar.gz” ，then ANDROID_SDK/hardware/realtek in it will be covered to hardwar/realtek directory of android source code.<br>
<br>
<b>Step 4：<br></b>
<br>
vim hardware/libhardware_legacy/wifi/Android.mk<br>

＃ifeq ($(BOARD_WLAN_DEVICE),UNITE)<br>＃  LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../external/wpa_supplicant_ath/wpa_supplicant/src/common<br>＃  LOCAL_SRC_FILES += wifi/wifi_unite.c<br>＃else ifeq ($(BOARD_WLAN_VENDOR), INTEL)<br>＃  LOCAL_SRC_FILES += wifi/wifi_intel.c<br>＃  LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../external/wpa_supplicant_8/src/common<br>＃else<br>＃  LOCAL_SRC_FILES += wifi/wifi.c<br>＃  LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../external/wpa_supplicant_8/src/common<br>＃endif<br>

else<br>
LOCAL_SRC_FILES += wifi/wifi.c<br>
endif<br>
<br>
<b>Step 5：<br></b>
<br>
Backup "wpa_supplicant_8" under "external/"of "android" souce code，then decompress "wpa_supplicant_8_kk_4.4_rtw_r10450.20140220.tar.gz" in the driving package and rename as "wpa_supplicant_8" and replaced to "external/" directory of "android" 。</span><br>
<br>
<b>Step 6：<br></b>
<br>
Modify "kernel_imx/arch/arm/configs/imx6_android_defconfig",(or modify ".config") configure the following items as "Y"
<br>
CONFIG_CFG80211=y<br>
<br>
CONFIG_MAC80211_MESH=y<br>
<br>
CONFIG_MAC80211=y<br>
<br>
CONFIG_HOSTAP=y<br>
<br>
CONFIG_USB_USBNET=y<br>

<b>Step 7: <br></b>
<br>
vim device/fsl/imx6/etc/init.rc<br>
<br>
:　setprop wifi.interface wlan0<br>
:　setprop wlan.driver.status "ok"<br>
<br>
<b>Step 8:<br></b>
<br>
Delete system folder in "out/target/product/sabresd_6dq" and folder of "wpa_supplicant_intermediates" in "out/target/product/sabresd_6d/obj/EXECUTABLES"，re-compile "system.img" and" boot.img".<br>
<br>
<b>Step 9：<br></b>
<br>
Compile "wlan.ko" and copy to directory of “system to /lib/modules/ ”<br>
<br>
vim Makefile<br>
CONFIG_PLATFORM_I386_PC = n<br>
<br>
CONFIG_PLATFORM_NEW = y<br>

...<br>
//    switchUser();<br>
<br>
<b>Step 3：<br></b>
Vim hardware/ril/runtime-ril-port/runtime_port.c<br>

:　　.dataport	= "/dev/ttyUSB0",<br>
:　　.type:　　= HUAWEI_MODEM,<br>
	},<br>
<br>
<b>Step 4：<br></b>
Copy ip-up,ip-down to directory of  /system/etc/ppp,copy libhuawei-ril.so to directory of  /system/lib. <br>
<br>
<b>Step 5:<br></b>
vim device/fsl/imx6/etc/init.rc<br>
<br>
Modify with following reference: <br>
chmod 777 /dev/ttyUSB0<br>
chmod 777 /dev/ttyUSB2<br>
chmod 777 /etc/ppp/ip-up<br>
chmod 777 /etc/ppp/ip-down<br>
＃service ril-daemon /system/bin/rild<br>
service ril-daemon /system/bin/rild -l /system/lib/libhuawei-ril.so<br>
<br>
<b>Step 6:<br></b>
Re-compile system.img and boot.img <br>
