ruth(MB511) device configure files for CM7, update rom status: RC Version 5

My ROM VERSION:
RUTEM_U3_01.14.16_DEBLUR_SIGNED_USARUTH15ND0RTINT056.0R_PDS000_USARUTHEHKTWEMARA_P011_A010_HWp3_1FF.sbf

RC version 5: v0.7.4
configure sources
gapps.zip

NOTICE:If you want update fix zip, you should use bootmenu to update.When boot at motologo,click click and click "vol -" to enter bootmenu. 

->because bootmenu executed by mot_boot_mode, so /system can't umount, only can remount.

--and update zip have to modify updater-script, remount /system.

can work:

camera

battd

fmradio

bluetooth

gps

sensors

usb connect

audio

half work:

video

-> 720p has problem.

wifi

->no softap.

ril

->I only use 2G service, so I can't test 3G.

flipout (rooted), conservative and powersave module of cpufreq

flipout has no compiled conservative and powersave of cpufreq in kernel.
but we can use compile kernel for modules.

module files:
cpufreq_conservative.ko
cpufreq_powersave.ko

BTW: flipout must be rooted.

xt502 CM7 z71 phone driver

when xt502 with CM7, the device become to z71 phone,
XP can't recognition the driver,
so we can use Google USB Driver package to install the driver.


1. download android SDK
2. use Android SDK Manager
3. in Extras, install Goole USB Driver package
4. the driver data will generated at extras directory
5. edit android_winusb.inf
the drive identify should be VID_0489&PID_C001
add to x86 or amd64


;Z71
%SingleAdbInterface%        = USB_Install, USB\VID_0489&PID_C001
%CompositeAdbInterface%     = USB_Install, USB\VID_0489&PID_C001&MI_01
;
6.install android_winusb.inf

Android 試寫!!

本來以為Android跟寫Java差不多...沒有到還差蠻多的XD
先前碰了幾次都沒辦法適應，直到最近上課有講到XML，
才能比較瞭解要怎麼下手。

所以XML還是必須要搞懂阿!!雖然只是標籤，卻相當的重要。
試寫過後覺得要寫好一支程式好困難，
其實我應該不會寫程式XD

目前寫的感想
-res 是寫Android重要的地方
|--drawable 目前覺得是放圖片的地方
|--layout 版面配置就靠這裡去維持啦!!
|--values 顏色，字串等就靠這裡去定義

之後就是開始寫邏輯觀念了。看到Button, EditText, Label
在畫面上一整個就很興奮，可惜還是不熟怎麼寫，
一堆觀念也不懂。雖然有去找別人的教學，卻還是相當的懵懂
想要問卻不知如何問，問別人問題真的是一件困難的事。
像是程式的生命週期從以前到現在我都還沒有好好的瞭解Orz
希望以後能夠完全理解!!
還有一個最重要的地方，非常重要阿!!
英文能力好真的是非常令人羨慕，我也要好好努力T.T
