Android APK forensic

Android apps’ APK could be easily retrieved after mobile has been rooted, by using ADB, File Manager, email, etc.

After got the APK, it could uses dex2jar to work with the classes.dex to investigate the details of the Java codes.

How-to
1. Extract the classes.dex from the APK by WinRAR, 7Zip, etc.

2. use “dex2jar" to de-compile the classes.dex to the jar file.

command: dj-dex2jar.bat classes.dex

3. use Java Decompiler to examine the Java source.

classes-dex2jar.jar de-compliled from RMapsExt3.1.5 (Special make for China which based from RMaps)

Tools reference:
1. dex2jar - Tools to work with android .dex and java .class files.

# The developer fixed the problem immediately after the bug reported yesterday.
And here is the new build.

2. JAVA environment must be installed in which for dex2jar to work.

3. Java Decompiler

ext2, ext3 and ext4 in Nexus One

Nexus One 改裝上 Evervolv Jellybean 的 nightly builds, 諗住把 sd 卡的 ext partition 換成 ext4，點知好不容易就 system crash，boot 返起無晒 sd-ext 內的 app, setting, etc.

要在 recovery fix ext partition，再 flash 過新 ROM, restore apps, 十級麻煩．

終於 Google 一下 ext2, ext3, ext4 的分別及用途．發現 ext3, ext4 係正，多左好多功能．不過用在 sd 等 flash 卡上．會增加 i/o 在 journalling 及增加 parallel 存取及多用戶情況的處理．

轉換在單機單用戶的 Android 上，反變成浪費資源既制肘．

早兩日開始更換為1G ext2 在 16G class 10 SD 卡上，給已成末代Nexus 最後一道甜點．期望能順利過渡，迎接下一隻 Android.

ASUS Transformer Prime ADB driver not working with exclamation mark

For those would like to "root" the ASUS Transformer Prime in Windows, all we need is the ADB driver, but most of the Google results shouldn't help.

After tried How to Install Transformer Prime USB Drivers on Windows! and [ADB/FB/APX Driver] Universal Naked Driver Beta 0.5, Only the Portable Devices - MTP (Media Device) could be recognized.

After all, goto Support For Eee Pad Transformer Prime TF201 -> Utilities -> ASUS Sync V1.0.76, install it. The PC will be rebooted and the yellow Exclamation Mark will go away!

Have fun with the ADB working fine (^^

anr_history.txt and Low on space

After my Nexus One flashed the custom ROM - eViL Sense v1.26 and partition the SDcard with 512M ext 3. Everything work great with additional storage which help a lot to install plently of apps (2xx).

Recently, it’s found that “Low on space” happened and even clear the storage, it’s still eat up the storage and “Low on space” appeared.

After checked, there have a file called anr_history.txt is grow up to 7X Mbytes which located at
/data/data/com.android.htcprofile

by using “du -sh *” at the folder /data/data.

Google it a lot & seems related to Dalvik but not much discussion found. As a result, working with below steps to clear the storage.

1. Backup using Nandroid.

2. Copy the anr_history.txt to /sdcard for restore backup when having problem.

cp anr_history.txt /sdcard

3. Clear the content of the anr_history.txt, "DON'T" rm it to avoid having file permission problem.

echo “ “ > anr_history.txt

4. Check the SD and phone storage

Storage restored to 8X Mbytes. Great!

Update:

ANR = Application Not Responding
using find the anr_history - "find / -name anr_history.txt"

脹卜卜, 肥嘟嘟鋰電池 + 手機電池膨脹，繼續使用會有何影響？

不經不覺,部 Hero 重度使用 15 個月, 再次 Cal 電也不濟 (Calibrate Battery) 況且, 跟機原裝電現在已變成脹卜卜, 肥嘟嘟.

星期六, 走進 298, shop 232 - Speedy Batteries 買 Momax x-level 電 ($110 discounted), 昨日長開 data connection & data sync, 晚上 9點還有+10%電量. 總萛有個不錯的交代.

有得換電就有這個好處, 不用特別付款買幾百元(每年) 的保養合約 (還有長長的 TOC) 或者加錢換新機.

換左電之後, FroydVillain 已開始 1.72 的旅程, 依家用 1.6 已經不錯, 期望好快就有 Hero 搭上 Gingerbread 的新版本 ROM 發佈.

Android - Offline 字典, Wordmate, 賽微隨身典 Cyberon Talking Dictionary

Android 常用的 offline 字典, 暫時比較好用的有賽微隨身典, 有發聲功能, 始終係 crack 版, 未必支援全部 Android 的解像度. 手上的 Hero with FroydVillain v.1.1.1 and Tattoo 2.1 就無緣喇, 反而 N1 original 2.2 就ok.

賽微隨身典破解版 Cyberon Talking Dictionary

其次, 長做長有的 Wordmate, 此版已經有好耐歷史, 無發聲功能, 依然好好用. 字庫和 Stardict 共用, 可在 sourceforge 找, tar bal format, 用 RAR 可以解開. 或者此 blog 底有zip 版的常用字庫以供下載.

解壓後, 放在 /sdcard/wordmate 即可.

Android - SPL, Fastboot, Recovery

當大家的 Android 手機開始陳舊, 跟不上時代步伐, 同時保養又好快到期. 睇怕只有出售僅有幾塊錢的"老拍檔" 或是上 xda forum, 找找 (同病相連的) hacker 特制 ROM.

這裡有幅關於 SPL, Fastboot, Recovery 的關係圖. 雖然睇完都未必知有咩用. 當 flash (刷) 得多, 救機救的多. 第日睇返一定會明白箇中奧秘.

Hero 2.1 的 official RUU 成功被 hack, 詳情請睇下面條 link, 成功 hack 了之後, 就可以刷 2.2 的 Hero custom ROM 喇.

Agile Stock 下架了 - Android Apps

不幸地, 簡單, 方便, 快捷的 Agile Stock 已經下架, 無法再在 Market 搵到.

雖然作者不再維護同修正, 同時在 Android 2.2 Fyoro 有幾百 % 的升降問題存在, 若還想使用, 用 Google search 一下, 應該唔難找回.

推(動)去寫 Apps - Google Android Lab

真估不到，Google Android Lab 的全部出席者，每人也可帶走一部 Superphone．

Rossi excited about his free Nexus One (Ryanne Lai @laihiu)

在 Lab 上，除左講解當前 Market 形勢, Market 方向後, 另外再介紹兩種處理 Android application 的方式.

第一是 Thread，點樣通過 Main UI，同各自創建的 Thread去互相溝通 [IPC]，其次，當遇上orientation change 時，application 會遇上什麼轉變．

第二是 Nexus One 的玄炫部份(Live wallpaper)，N1 經過強悍的 Qualcomm Snagdragon 加持，背景行 services 己不再察覺會拖延 active application. 往後推出的 applications，能夠處理得更複雜，更全面．到其時，只會怕電池耗光．

這部 Nexus One 真是一個好好的 bonus，正好給老婆把 HTC Tattoo 打入冷宮．雖則 Tattoo 不錯，只可惜屏幕細...

當初，因為睇 Professional Android Application Development，對發展 app 產生興趣，既然收到 Google 厚禮，同時家中陳舊 desktop 已經轉身成為 Core i5 - 750，推 Android SDK 已經卓卓有餘．期望將來能抽多點時間，完成腦海中的 apps.
