Android - 撥號字串 android_secret_code

如何在Android中 撥號程式裡面 打入特別字串 就會出現測試模式
Android中 這個號碼有固定格式 *#*# 開頭，#*#*結尾的撥號字串

Ex:進入撥號程式，輸入*#*#4636#*#* 可以看到一個測試發佈文章應用
Step:1. AndroidManifest.xml添加Filter就可以
<br><receiver android:name="TestingSettingsBroadcastReceiver"><br> <intent-filter><br> <action android:name="android.provider.Telephony.SECRET_CODE" /><br> <data android:scheme="android_secret_code" android:host="4636" /><br> </intent-filter><br> </receiver><br>

2. Write a class: TestingSettingsBroadcastReceiver
<br>public class TestingSettingsBroadcastReceiver extends BroadcastReceiver { //繼承 BroadcastReceiver<br>public TestingSettingsBroadcastReceiver() { } <br><br>@Override <br>public void onReceive(Context context, Intent intent)<br>{ <br>if (intent.getAction().equals(SECRET_CODE_ACTION))<br>{ //new a Intent for next activity<br>Intent i = new Intent(Intent.ACTION_MAIN); <br>i.setClass(context, >TestingSettings.class); // next activity class<br>i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); <br>context.startActivity(i); <br>} <br>} <br>}<br>
========================================
查看Phone的原始程式碼 SpecialCharSequenceMgr.java，
有一個函數專門處理*#*# 開頭，#*#*結尾的撥號字串。

<br>/**<br>* Handles secret codes to launch arbitrary activities in the form of *#*##*#*.<br>* If a secret code is encountered an Intent is started with the android_secret_code://<br>* URI.<br>*<br>* @param context the context to use<br>* @param input the text to check for a secret code in<br>* @return true if a secret code was encountered<br>*/<br>static private boolean handleSecretCode(Context context, String input) {<br>// Secret codes are in the form *#*##*#*<br>int len = input.length();<br>if (len > 8 && input.startsWith("*#*#") && input.endsWith("#*#*")) {<br>Intent intent = new Intent(Intents.SECRET_CODE_ACTION,<br>Uri.parse("android_secret_code://" + input.substring(4, len - 4)));<br>context.sendBroadcast(intent);<br>return true;<br>}<br><br>return false;<br>}<br>

proguard 連結

ProGuard

The ProGuard tool shrinks, optimizes, and obfuscates your code by removing unused code and renaming classes, fields, and methods with semantically obscure names. The result is a smaller sized .apk file that is more difficult to reverse engineer. Because ProGuard makes your application harder to reverse engineer, it is important that you use it when your application utilizes features that are sensitive to security like when you areLicensing Your Applications.

ProGuard is integrated into the Android build system, so you do not have to invoke it manually. ProGuard runs only when you build your application in release mode, so you do not have to deal with obfuscated code when you build your application in debug mode. Having ProGuard run is completely optional, but highly recommended.

Samba 開啟分享 筆記

不知道是從哪邊抓到了 蠻詳細的 保存下來

[Samba基本設定] -test on ubuntu 10.10 (OK)

1.目的
讓 Linux 與 Windows 的機器能共享資源。
所使用的 protocol 為 SMB 。

2.所需套件
samba-common , samba 以及 samba-client
(一). service 的名稱為：smb
(二). 在 samba 中，主要的 daemon 有 smbd / nmbd ，各肩負不同的責任：
a. smbd：File and Printer Sharing
b. nmbd：Resource Browsing / WINS Server
相關紀錄檔(Log)檔在 /var/log/samba 下。

3.samba 的設定檔為 /etc/samba/smb.conf。
其中以 # 或 ; 為首的資料行被視為註解。

4.預設的設定檔，內有三段：
[global]
workgroup = __________ # Workgroup / Domain Name
server string = _________ # 說明文字
log file = /var/log/samba/%m.log # %m --> The NetBIOS Name of client host
security = user # Or Anonymous
encrypt password = yes
smb password file = /etc/samba/smbpasswd
netbios name = ________ # 若無指定，預設為 hostname

[homes]
comment = home Directories
browseable = no
writable = yes
valid users = %S # %S --> User
create mode = 0664
directory mode = 0775

[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
guest ok = no # guest ok = yes 等同 public = yes
writable = no
printable = yes # 印表機特定選項

5.檢測 smb.conf：
　# testparm

6.啟動 samba：
# service smb [ status | start | stop | restart ]

[On ubuntu 10.10]

# service smbd [ status | start | stop | restart ]

7.查看特定主機分享出的資源：
# smbclient -L 主機之NetBIOS名稱

8.[nmblookup]
a. 要查詢在目前的區域網路上是否有哪台主機之 NetBIOS name 為某個字
時，可以使用 nmblookup ，如 # nmblookup NetBIOSName
b. 也可用來像某台 WINS server 查詢：
# nmblookup -U wins_server -R NetBIOSName

9.要讓使用者以 john 的身分來使用 samba server 上的資源時，步驟如下：
(請留意 encrypt password = 及 smb passwd file =)
a. 在 samba server 上建立帳號
b. 利用 smbpasswd -a 為 john 設定 samba 的密碼
c. 利用 smbclient //host//homes -U john 測試

10.使用某 windows 網路上某台機器所分享出來的資源：
a. smbclient 資源名稱 -U 使用者名稱
# smbclient //hostname/test -U username
b. 把 windows 上的一個資源掛載(mount)過來
mount
# mount -t smbfs -o passwd=xxx //host/docs /mnt/samba
smbmount

11.請嘗試建立兩個 share
a. myshare：讓所有人均可讀取。
b. rhce：只有屬於 rhce 群組的使用者才可以存取。
[myshare]
path = /tmp/test
browseable = yes
public = yes
writeable = yes
[rhce]
path = /tmp/rhce
browseable = no
public = no
valid users = john , mary , @rhce
writeable = yes

12.利用 swat 來設定 samba

13.smbstatus 可用來顯示目前有多少客戶端正在使用本機所提供的 samba 服務

Lua與C語言的結合- Part1 設定檔的應用

Lua是一個C語言寫成的script language.

Lua是什麼 google 一下就有了 我擷取wiki的一部分資料來使用

Lua 的wiki (http://zh.wikipedia.org/w/index.php?title=Lua&variant=zh-hant)

特性

Lua是一種輕量語言，它的官方版本只包括一個精簡的核心和最基本的庫。這使得Lua體積小、啟動速度快。它用標準C語言編寫並以源代碼形式開放，編譯後僅僅一百餘K，可以很方便的嵌入別的程式裡。和許多"大而全"的語言不一樣，網路通訊、圖形界面等都沒有預設提供。但是Lua可以很容易地被擴展：由宿主語言（通常是C或C++）提供這些功能，Lua可以使用它們，就像是本來就內置的功能一樣。事實上，現在已經有很多成熟的擴展模塊可供選用。

Lua是一種多重編程範式的程式設計語言：它只提供了很小的一個特性集合來滿足不同編輯範式的需要，而不是為某種特定的編輯範式提供繁雜的特性支援。例如，Lua並不提供繼承這個特性，但是你可以用元表來模擬它。諸如名字空間、類這些概念都沒有在語言基本特性中實現，但是我們可以輕易的用表結構（Lua唯一提供的複雜數據結構）輕易模擬。Lua可以在運行時隨時構造出一個函數，並把它看作一個對象（正是所謂的first class function），這個特性可以很好的滿足函數式編程的需要。這是提供了這些基本的元特性，我們可以任意的對語言進行自需的改造。

Lua原生支援的數據類型非常之少，它只提供了 數字（缺省是雙精度浮點數，可配置）、布爾量、字符串、表、子程序、協程（coroutine）以及用戶自定義數據這幾種。但是其處理表和字符串的效率非常之高，加上元表的支援，我們可以高效的模擬出需要的複雜數據類型（比如集合、數組等）。

Lua是一個動態弱類型語言，支援增量式垃圾收集策略。有內建的，與操作系統無關的協作式多線程（coroutine）支援。

================================================================

比起python perl來說lua非常的小 資源需求量也很低

Perl的原始碼 很亂 有些架構上 非常不適合C/C++ embed

python 就好很多 python 比起來 比perl好學 也好debug多

至於embed這方便 也處理得非常好 python架構有想到embed這一塊

但是python有一個缺點 就是他需要C++的compiler

那我們可以拿Lua作什麼用 除了拿來作script engine外

因為1. Lua 需求資源少 2.Lua API 好使用 3. 當檔案文法錯誤 會有訊息指出

還有一個很有用的功能 就是 當作"設定檔"或是"文字資源檔"

接下來 提供下面的作法 跟大家分享

1.Init lua

2. Load Lua file

3. How to trace lua object

前置作業 到Lua的網站download一份原始碼 跟你的程式結合在一起
Lua 5.1.4 Link: http://www.lua.org/ftp/lua-5.1.4.tar.gz

1.如何init Lua

lua_State 可以產生很多個 每一個代表一個Lua virtual machine

這也是lua 有考慮到embed之後的設計 ,perl就沒有這樣的好處

<br />#ifdef __cplusplus<br />extern "C" {<br />#endif<br />#include "lua.h"<br />#include "lauxlib.h"<br />#include "lualib.h"<br />#ifdef __cplusplus<br />}<br />#endif<br /><br /><br />lua_State* g_pLuaState = NULL; <br />g_pLuaState = lua_open(); <br />........................................ <br />if (g_pLuaState) { lua_close(g_pLuaState); g_pLuaState = NULL; }<br />

2. Load Lua file

<br />BOOL loadLuaFile(const wchar_t* cszIniPath) <br />{ <br /> char szIniFileNameA[MAX_PATH*2]; <br /> int status; BOOL bRet = TRUE; <br /> WideCharToMultiByte(CP_ACP,0,cszIniPath,-1,szIniFileNameA,MAX_PATH*2,0,0); //Lua loadfile only support ANSI string. <br /> status = luaL_loadfile(g_pLuaState, szIniFileNameA); <br /> if ( 0 == status ) status = lua_pcall(g_pLuaState, 0, 0, 0); <br /> if ( 0 != status ) <br /> { //pop up error msg <br /> if (status && !lua_isnil(g_pLuaState, -1)) <br /> { <br /> const char *msg = lua_tostring(g_pLuaState, -1); <br /> if (msg == NULL) msg = "(error object is not a string)"; <br /> _tprintf(_T("<err>Load Lua file fail. FILE PATH=%hs\n Msg:%hs\n"),szIniFileNameA,msg); //pop lua stack for error message. <br /> lua_pop(g_pLuaState, 1); <br /> } <br /> bRet = FALSE; <br /> } <br />return bRet; <br />}<br />

3. Trace Lua object.

這邊提供一個trace/dump object的function
可以參考codes的作法 可以隨意implement 自己讀取變數或是儲存變數的函式
這邊 有一個非常重要的一點 就是 如何trace table
一般都會用 lua_objlen() 去讀取table的obj len
但是 你會發現 會有點怪怪的
如果你的table裡面 有另外一個table你會發現 lua_objlen()回來的數字並不包含sub-table
這個部分 我有機會 再另外開一篇來解釋這個東西
如果 你的table不會有含有string-index的table 請用lua-objlen() 然後用index去取得obj
要完整的trace一個table 要利用 lua_next() api (這樣出來的順序是不固定的)
如何使用請參考我提供的codes

setting.lua
----------------------------
<br />ConfigDB = {<br /> Name = {"Test" },<br /> ["Version"] = "10000",<br /> ["Enable"] = false,<br /> ["Profile"] = {<br /> ["Profile1"] = {<br /> ["Name"] = "AAA",<br /> ["ID"] = 12345,<br /> },<br /> ["Profile2"] = {<br /> ["Name"] = "BBB",<br /> ["ID"] = 123,<br /> },<br /> },<br /> "111",<br /> 111,<br /> [5]="Aaa",<br /> {1,2,3,4,5}<br />}<br />
----------------------------


trace後的結果
----------------------------
