Enabling wireless tools on Android I need to use commands like iwconfig in Android, I know I have to install the wireless tools because they are not in Android by default, The problem is that I have just seen 3 chinesse tutorials that makes no sense when I translate them, and a link that downloads a directory with Android wireless tools, but I don't know what to do to get them into my device and use them. 

Any help would be apreciated.
Download wireless_tools.30.pre9.tar.gz.
This version supports non-ASCII char in ESSID.
Unpack it into mydroid/external/wireless-tools directory.
Create Android.mk file with the following content:

LOCAL_PATH:= $(call my-dir)
################## build iwlib ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlib.c
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= libiw
LOCAL_STATIC_LIBRARIES := libcutils libc libm
include $(BUILD_STATIC_LIBRARY)
################## build iwconfig #################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwconfig.c
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= iwconfig
LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
#LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
#LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
#LOCAL_MODULE_TAGS := eng user
include $(BUILD_EXECUTABLE)
################## build iwlist ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlist.c iwlib.h
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= iwlist
LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
#LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
#LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
#LOCAL_MODULE_TAGS := eng user
include $(BUILD_EXECUTABLE)

Modify it as follows:


Change wireless.22.h to be wireless.h ;
Modify ifrename.c , add getline() function. You can get the code from external/genext2fs/genext2fs.c ;
Notice that this file uses macro to pass another function to getline() .
Modify iwlib.h ,  change #include to be #include .
[You might need to check the original file to know what the author means]

Compile

~/eclair-21/external/wireless-tools$ . ../../build/envsetup.sh
~/eclair-21/external/wireless-tools/wireless-tools$ mm

Copy files to the system

~/eclair-21/external/wireless-tools$ croot
~/eclair-21$ cp out/target/product/generic/system/xbin/iwconfig /nfs/rootfs/system/xbin/iwconfig
~/eclair-21$ cp out/target/product/generic/system/xbin/iwlist /nfs/rootfs/system/xbin/
