Rockie's Android Porting Guide（5）——Change your location and add the screenlock

Rockie Cheng

Today ,I just solved two small questions.
One is changing the system location to CHINA, the other one likes a gift more ,
--a screen lock--and I do not know how to get it.

(I) Change the system location
simple and simple
at the end of build/target/product/idea6410.mk
add this:

CUSTOM_LOCALES := zh_CN

Of coures, you have many choises:
ldpi /
hdpi /
mdpi /
en_US /
en_GB /
en_CA /
en_AU /
en_NZ /
en_SG /
ja_JP /
fr_FR /
fr_BE /
fr_CA /
fr_CH /
it_IT /
it_CH /
es_ES /
de_DE /
de_AT /
de_CH /
de_LI /
nl_NL /
nl_BE /
cs_CZ /
pl_PL /
zh_CN /
zh_TW /
ru_RU /
ko_KR

(II) Add the screenlock

I have wasted the whole morning online to serch a way to add the screenlock, but no answer.
Then ,I find that build/target/product/sdk.mk has more apps than generic.mk,so I decide to put them in my idea6410.mk.
Luckly,the Screenlock appears and the keyboard(lock & unclok) is working well.

That must be one of the apks ,who can tell one which one?
SoftKeyboard/LiveWallpapersPicker or Fallback?

sdk.mk
AccountAndSyncSettings /
AlarmClock /
Camera /
Calculator /
Development /
DrmProvider /
Email /
Fallback /
GPSEnable /
Launcher /
Music /
Mms /
Settings /
SdkSetup /
CustomLocale /
gpstest /
sqlite3 /
LatinIME /
PinyinIME /
OpenWnn /
libWnnEngDic /
libWnnJpnDic /
libwnndict /
CertInstaller /
LiveWallpapersPicker /
ApiDemos /
GestureBuilder /
SoftKeyboard

generic.mk
    AccountAndSyncSettings /
    AlarmClock /
    AlarmProvider /
    Bluetooth /
    Calculator /
    Calendar /
    Camera /
    CertInstaller /
    DrmProvider /
    Email /
    Gallery /
    LatinIME /
    Mms /
    Music /
    Settings /
    Sync /
    Updater /
    CalendarProvider /
    SyncProvider

BTW: Fix a bug about KCM files

W/KeyCharacterMap( 401): Can't open keycharmap file
W/KeyCharacterMap( 401): Error loading keycharmap file '/system/usr/keychars/gpio-keys.kcm.bin'. hw.keyboards.0.devname='gpio-keys'
W/KeyCharacterMap( 401): Can't open keycharmap file
E/KeyCharacterMap( 401): Can't find any keycharmaps (also tried /system/usr/keychars/qwerty.kcm.bin)
I/DEBUG   ( 414): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
I/DEBUG   ( 414): Build fingerprint: 'idea6410/idea6410/idea6410/:Eclair/ECLAIR/eng.kyon.20091226.183935:eng/test-keys'
I/DEBUG   ( 414): pid: 401, tid: 401 >>> android.process.acore <<<
I/DEBUG   ( 414): signal 11 (SIGSEGV), fault addr 00000004

I rebuild the whole codes for more than ten times and finally find that keypoint "No Read Right"

Solution:
add this to your init.rc

chmod 777 system/usr/keychars/gpio-keys.kcm.bin
