ethernet으로 Wi-Fi 연결 fake

ODROID에 Ethernet port가 있고 기본적으로 dhcp가 가능한 회선에 연결하면 Wi-Fi  연결되어 있지 않아도 인터넷이 가능합니다.

하지면 몇몇 app들은 Mobile Network 또는 Wi-Fi  연결만을 체크하도록 되어 있어서 실행이 안되는 경우가 있습니다.

Ethernet 연결을 Wi-Fi 연결로 사용하여 android에서 Wi-Fi  연결된것 처럼 만들고 싶은데 관련 자료를 못찾겠네요.

아래의 그림과 같이 android는 wlan0가 wpa_supplicant와 연결되어 있습니다. 여기서  wlan0에 eth0를 어떻게 연결할지 생각되는 시나리오 들입니다.

wlan0 -> wpa_supplicant->android

 ^                       ^
  | ?(route)        | ( wpa_supplicant -ieth0 -Dwired)?
eth0    --------->           

1. wpa_supplicant -ieth0 -Dwired 옵션으로 ethernet을 연결
- 단 wpa_supplicant가 두개가 존재해야 하고 서비스 역시 두개가 되어야 한네요.
(wpa_supplicnat -iwlan -Dwext)
- "-Dwired"가 동작하기 위해 wpa_supplicant가 BOARD_WPA_SUPPLICANT_DRIVER := WIRED로 동작 확인이 먼저 일 듯 합니다.

2. eth0을 route하여 wlan0에 연결 
- 하지만 wpa_supplicant 때문에 SSID등 연결된 상태로 만들기가 가능 할지 모르겠네요.

3. reverse tethering
- 이건 pc의 인터넷 연결을 USB(adb)로 스마트폰으로 연결해주는 기술인데 자세한 자료는 없고 howto만 보이네요. usb tethering apk 소스가 필요할 듯 합니다.
- 이건 기본적으로 eth0로 네트워크가 연결되어 있고 Wi-Fi 연결로 속일 수 없어서 안 될것 같은데 몇몇 동영상을 찾아 보면 3G Network 연결로 만드는 듯 하여 Wi-Fi가 아니라 Mobile Network로 연결된다면 가능할 것 같습니다.

MK802 란 모델이 위에 설명한 방법으로 Network이 구성이 된다고 합니다.


아래 주소에서 reverse tethering 소스를 구할 수 있습니다.

Pinch to zoom with mouse wheel.

Pinch to Zoom with mouse wheel.

You can test it.

download libinput.so here.

https://docs.google.com/file/d/0B5aZmgmqP9rOYlJ5eHR1bjFnRzA/edit?usp=sharing

$adb remount

$adb push libinput.so /system/lib/

adb shell sendevent로 pinch zoom in/out

adb shell sendevent로 android에 input event를 가상으로 보낼 수 있습니다.

http://toors.tistory.com/entry/android-touch-move-event-%EC%83%9D%EC%84%B1

위에 링크처럼 하면 move와 같이 single  touch event는 만들 수 있습니다.

pinch zoom in/out과 같은 multi touch event도 만들 수 있습니다.

getevent에서 odroidx-ts가 touch screen device이고 node는 event1입니다.

# getevent                                                    
add device 1: /dev/input/event0                                              
  name:     "odroid-keypad"                                                  
add device 2: /dev/input/event2                                              
  name:     "Microsoft Microsoft 3-Button Mouse with IntelliEye(TM)"          
add device 3: /dev/input/event1                                              
  name:     "odroidx-ts"


저의 시스템에서 touch의 노드는 /dev/input/event3입니다.

sh로 만드실 경우 system을 없애고 "adb shell sendevent"로 고치시면 됩니다.


//첫번째 pointer의 ABS_MT_TRACKING_ID를 1로 설정한다.
system("sendevent /dev/input/event1 3 57 1");
system("sendevent /dev/input/event1 3 53 %d", X1);
system("sendevent /dev/input/event1 3 54 %d", Y1);
//ABS_MT_PRESSURE 8정도의 값을 보내서 press 되었다고 알려 줍니다.
system("sendevent /dev/input/event1 3 58 8");
//한 pointer에 대한 EV_SYN, SYN_REPORT를 보낸다.
system("sendevent /dev/input/event3 0 0 0");


//두번째 pointer 입력 전에 ABS_MT_SLOT을 보낸다.
system("sendevent /dev/input/event3 3 47 1");


//두번째 pointer의 위치를 정한다.
X1 = X2 + 50;
Y2 = Y2 + 50;


//두번째 pointer
//첫번째 pointer의 ABS_MT_TRACKING_ID를 2로 설정한다.
system("sendevent /dev/input/event1 3 57 2");
system("sendevent /dev/input/event1 3 53 %d", X2);
system("sendevent /dev/input/event1 3 54 %d", Y2);  
system("sendevent /dev/input/event1 3 58 8");
system("sendevent /dev/input/event1 0 0 0");


//여기서 ABS_MT_POSITION_X(53), ABS_MT_POSITION_Y(54), 그리고 SYN_REPORT를 한 묶음으로 이동하고 싶은 만큼 반복한다.
system("sendevent /dev/input/event1 3 53 %d", X2 += 20);
system("sendevent /dev/input/event1 3 54 %d", Y2 += 20);
system("sendevent /dev/input/event1 0 0 0");


//첫번째 pointer의 ABS_MT_TR두ACKING_ID를 -1을 초기화 한다.
system("sendevent /dev/input/event1 3 57 -1");
system("sendevent /dev/input/event1 0 0 0");
//ABS_MT_SLOT(47)은 0,1로 번갈아 입력된다. 앞에서 1로 보냈으니 0으로 보낸다.
system("sendevent /dev/input/event1 3 47 0");
//두번째 pointer의 ABS_MT_TRACKING_ID를 -1을 초기화 한다.
system("sendevent /dev/input/event1 3 57 -1");
system("sendevent /dev/input/event1 0 0 0");

--------------------------------------------------------------------------------------------------

bionic/libc/kernel/common/linux/input.h에 define 되어 있습니다.

#define EV_ABS 0x03
#define ABS_MT_POSITION_X 0x35  -> 57(십진수)

#define ABS_MT_POSITION_Y 0x36 - > 58(십진수)
#define ABS_MT_PRESSURE 0x3a



아래와 같이 getevent -l 로 event를 확인 할 수 있는데 Multi touch시에 event가 어떻게 들어 오는지 확인하여 pinch zoom을 구현해 봤습니다.


$ adb shell getevent -l

Makefile에서 "-=" 문제

android 4.1.1에서 busybox가 컴파일이 안된다.
문제는 -fno-strict-volatile-bitfields다.
4.2.1에서는 컴파일이 되는데 4.1.1에서는 안된다.

build/core/combo/TARGET_linux-arm.mk


120 # by turning off the builtin sin function.                          
121 ifneq ($(filter 4.6.%, $(shell $(TARGET_CC) --version)),)          
122 TARGET_GLOBAL_CFLAGS += -Wno-unused-but-set-variable -fno-builtin-sin \
123             -fno-strict-volatile-bitfields                                                          
124 endif

그래서 저 옵션만 끄면 되것 같아서 아래와 같이 해 보았다.

TARGET_GLOBAL_CFLAGS -= -fno-strict-volatile-bitfields

물론 -=가 될줄 알았는데 안된다.

그래서 할 수 없이 TARGET_GLOBAL_CFLAGS에서 -fno-strict-volatile-bitfields를 없애고 다른 변수를 선언하기로 했다.

TARGET_GLOBAL_CFLAGS2 := $(shell echo $(TARGET_GLOBAL_CFLAGS) | sed 's/-fno-strict-volatile-bitfields/ /g')

Navigation Bar에 volume up/down, Shutdown, Screenshot 버튼 넣어보기

Tablet UI에서 back, home. recent app 옆에  volume up/down, Shutdown, Screenshot button을 넣어보자.

먼저 frameworks/base/packages/SystemUI/res/drawable-[h,m,x]dpi/에

ic_sysbar_home.png와 동일한 크기의 

ic_sysbar_plus,png, ic_sysbar_minus.png, ic_sysbar_shutdown.png, ic_sysbar_screenshot.png 이란 이미지를 준비합니다.

frameworks/base/packages/SystemUI/res/layout/navigation_bar.xml 에 recent_apps 다음에 4개의 항목을 추가합니다.

 <com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/recent_apps"

                android:layout_width="80dp"

                android:layout_height="match_parent"

                android:src="@drawable/ic_sysbar_recent"

                android:layout_weight="0"

                systemui:glowBackground="@drawable/ic_sysbar_highlight"

                android:contentDescription="@string/accessibility_recent"

                />

            <com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/vol_plus"

                android:layout_width="80dp"

                android:layout_height="match_parent"

                android:src="@drawable/ic_sysbar_plus"

                android:layout_weight="0"

                systemui:glowBackground="@drawable/ic_sysbar_highlight"

                android:contentDescription="@string/accessibility_recent"

                />

            <com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/vol_minus"

                android:layout_width="80dp"

                android:layout_height="match_parent"

                android:src="@drawable/ic_sysbar_minus"

                android:layout_weight="0"

                systemui:glowBackground="@drawable/ic_sysbar_highlight"

                android:contentDescription="@string/accessibility_recent"

                />

            <com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/shutdown"

                android:layout_width="80dp"

                android:layout_height="match_parent"

                android:src="@drawable/ic_sysbar_shutdown"

                android:layout_weight="0"

                systemui:glowBackground="@drawable/ic_sysbar_highlight"

                android:contentDescription="@string/accessibility_recent"

                />

            <com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/screenshot"

                android:layout_width="80dp"

                android:layout_height="match_parent"

                android:src="@drawable/ic_sysbar_screenshot"

                android:layout_weight="0"

                systemui:glowBackground="@drawable/ic_sysbar_highlight"

                android:contentDescription="@string/accessibility_recent"

                />

frameworks/base/packages/SystemUI/res/layout-sw600dp/status_bar.xml도 동일하게 수정 합니다.

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/tablet/TabletStatusBar.java 에서 volume up/down과 shutdown을 구현합니다.

자동으로 Wi-Fi on/off하기

무제한 요금제를 사용하지만 Wi-Fi의 환경이 더 빠르기 때문에 사무실이나 집에서 전원을 연결하고 Wi-Fi를 사용합니다.
그리고 이동 중에는 Wi-Fi를 off합니다.
그래서 자동으로 충전 중이면 Wi-Fi를 켜주고 충전이 아니면 Wi-Fi를 끄는 app을 만들어 봤습니다.

추가적으로 빈 Activity에 사용여부 확인 가능한 checkbox를 추가하였습니다.

http://dl.dropbox.com/u/4485660/WiFiAuto.apk

아주 간단한 프로그램인데 BroadcastReceiver 상속받은 class만으로 app을 만들어 보니 ACTION_POWER_CONNECT intent를 못 받아서 삽질 좀 했네요.
그래서 아무 동작하지 않는 Activity를 추가 하였습니다.


--- ACConnectReceiver.java ---


package com.hardkernel.odroid.wifiauto;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.WifiManager;

public class ACConnectReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String action = intent.getAction();
WifiManager manager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (action.equals(Intent.ACTION_POWER_CONNECTED)) {
manager.setWifiEnabled(true);
} else if (action.equals(Intent.ACTION_POWER_DISCONNECTED)) {
manager.setWifiEnabled(false);
}
}

}


--- MainActivity.java ---



package com.hardkernel.odroid.wifiauto;

import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

setContentView(R.layout.main_layout);

CheckBox cbUse = (CheckBox)findViewById(R.id.cb_use);
cbUse.setOnCheckedChangeListener(new OnCheckedChangeListener () {

@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
// TODO Auto-generated method stub
SharedPreferences prefs = getSharedPreferences("PreName", MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("Use", isChecked);
editor.commit();
}

});

SharedPreferences prefs = getSharedPreferences("PreName", MODE_PRIVATE);
cbUse.setChecked(prefs.getBoolean("Use", true));
}

}

sun-java6-jdk deb 직접 만들어 사용하기

synaptic에서 더 이상 sun-java6-jdk package를 설치 할 수 없습니다.
그래서 직접 만들어 사용하는 방법이 있어서 소개 합니다.

http://blog.flexion.org/2012/01/16/install-sun-java-6-jre-jdk-from-deb-packages/

위에 페이지에서 git 주소가 있습니다.

https://github.com/flexiondotorg/oab-java6

git로 부터 소스를 받습니다.

$mkdir sun-java
$cd sun-java
$git clone git://githbu.com/rraptorr/sun-java6.git
$cd sun-java6
$sudo apt-get install dpkg-dev

현재 폴더에서 jdk-6u35-linux-i586.bin과 jdk-6u35-x64.bin 두 파일을 아래 사이트에서 받습니다.

http://www.oracle.com/technetwork/java/javase/downloads/jdk6u35-downloads-1836443.html

그리고 jce_policy-6.zip을 아래 사이트에서 받습니다.
http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html

$dpkg-buildpackage -uc -us

몇몇 패키지가 없다고 에러가 나면 설치하고 계속 진행합니다.
성공하고 상위 폴더로 이동하면 deb 파일들이 보입니다.

먼저 java-common을 설치하여 주시고 패키지 의존성에 맞게 순서대로 설치 하시면 됩니다.
