Android 的 layout renderer 並沒有聰明到可以自動去取消每一個 runtime 的程式碼
所以很多時候 onFinishLayout() 裡，onAttachToWindow() 裡
常會有一些 runtime 才會拿得到的東西
這會造成 layout renderer 直接死給你看
解法很簡單
用 isInEditMode() 去把這些 renderer 無法處理的東西包起來
(或者是直接 early return)
或者是之前講的這個...要在 renderer 裡顯示沒有的東西 View.isInEditMode()
很遺憾的是...連 Google 自己都不鳥這個 =__=
看到 BSP 裡不知道在修啥 bug, 把 aosp 原來的 code wrap 了一個 null check 本來可以寫成 early return 結果硬要用 if-else 包起來
private int getWidgetPosition(int id) {
if (mAppWidgetContainer != null) {
// 原來的 code
} else {
return -1;
}
}
一般的 git show or diff 跑出洋洋灑灑的一大片無意義的的畫面 雖然可以下參數避掉, 不過一般還是會用 raw diff 看有沒有多的垃圾
整排indent 的結果 造成整個 diff 多了十行 每次看到這種 code 一整個想翻桌
2d14654 HEAD@{0}: commit (amend): Other's patch
428555b HEAD@{1}: commit: Other's patch
bd33767 HEAD@{2}: commit: Previous one
$ git reset --hard HEAD~1
HEAD is now at bd33767 Previous one
$ git cherry-pick 428555b
....
$ git diff 428555b 2d14654 | git apply -
這時打 git status 就可以發現當初的修改回來 unstage 的狀態了, 重新 git commit
$ git commit
完成
Tested in KRT16M / KOT49H
Follow the steps here
http://source.android.com/source/building.html
get source code Version
get nexus driver
fix what's missing in nexus driver
link
yes, pull the binary from stock ROM first
If you didn't do that, your SIM cannot be used
(optional) get /system/media/bootanimation.zip Because AOSP android doesn't have nexus animation
(ADD: 2013/11/29 16:55) add Network Location Provider for GMS
link
Fixed Wireless GPS issues. Changed "config_locationProviderPackageNames" from "com.google.android.location" to "com.google.android.gms" in frameworks/base/core/res/res/values/config.xml
start to build
$ source build/envsetup.sh
$ lunch
=> Press AOSP hammerhead userdebug
$ make clobber
$ make -j 4
flash custom recovery (CWM or TWRP)
flash everything other than recovery
fastboot reboot bootloader
Press VOL-UP than power button to enter recovery mode
Choose Advanced -> sideload mode, if you are using TWRP
$ adb sideload gapps
gapps link http://forum.xda-developers.com/showthread.php?t=2397942
$ adb sideload stock_boot_animation or
adb push bootanimation.zip into /system/media/bootanimation.zip
do a factory reset
(ADD: 2013/12/19 16:07)
fix green line issue in camcorder KOT49H (KRT16M has this issue?)
Replace /system/lib/libmmcamera_interface.so by stock one

Have fun!
在找 OnSharedPreferenceChangeListener 範例抄時找到這個
SharedPreferences keeps listeners in a WeakHashMap. This means that you cannot use an anonymous inner class as a listener, as it will become the target of garbage collection as soon as you leave the current scope.
SharedPreferences.onSharedPreferenceChangeListener not being called consistently
靠... 這很容易踩到啊 =_=
plurka 廣告設計得太爛，不要怪我對你不義啊
記錄一下
adb shell mount -o rw,remount /system
adb push hosts.for.mobile.txt /etc/hosts
adb reboot
refs: xda
xcode-select --install 後還是不在, 用 Mac Ports 吧
$ sudo ports install apache-ant
啟動後的 navigation bar 跟 orietation 一整個亂七八糟
解法: 升級到 1.3.1
http://stackoverflow.com/questions/19561669/error-on-loading-genymotion-device-on-os-x-mavericks
更新到 10.0 後, 9.0.9 被搬到 /Application/iMovie 9.0.9 下面
iWork 也是還存在
應該可以砍了吧 = ="
以前按一下電源鈕會跑出電源選單，現在只會直接睡著
解法: 長按 1.5 秒

因為我一直以為只對 Keynote 有需求，所以我當初只買了 Keynote
Pages / Numbers 在試用期過後就放著讓他可以開檔案
結果這次搞一搞他就變正式版了 wwwww

gnutar 找不到
暫時解法:
sudo ln -s /usr/bin/tar /usr/bin/gnutar
不過 darwin12 != darwin13 只能等官方修吧 QQ

陸續更新...
常用的指令例如 status 可以減化成短指令
~/.gitconfig
[alias]
ci = commit
st = status
co = checkout
l = log --stat=140,100
br = branch
p = cherry-pick
r = rebase
f = fetch
up = pull --rebase
指令就變為
$ git st
單獨 git clone 下來的 git repository 不會有 commit-msg hook
所以 push 到 gerrit 時，不會有 Change-Id
沒有 Change-Id 的話，重複 push 不會在同一個 patch 裡繼續疊加
所以 commit-msg hook 是必需要用的
(除非要手動從 gerrit 上 copy 下來...何苦呢...)
$ find . -name commit-msg \<BSP_ROOT>/.repo
把他 copy 到 .git/hooks/ 裡
$ scp -p -P 29418 \<SERVER>:hooks/commit-msg .git/hooks/
每次 git repository commit 時，如果要填寫固定格式
可以先將文字檔存下來，就不會每次都要打一次
進 git repository 寫一個文字檔 .gittemplate
$ git config commit.template=.gittemplate
放在 ~/.gitconfig 裡指定
[commit]
template = ~/.gittemplate
$ git push ssh://\<SERVER>:29418/\<PATH> HEAD:refs/for/\<BRANCH>
PATH 可以使用
$ git config -l | grep url remote.origin.url=ssh://\<SERVER>:29418/here/is/my/branch
在此可以知道路徑是 here/is/my/branch
BRANCH
$ git branch -a
...
remotes/origin/aosp/jb-release
...
在裡面找需要的 branch, 不需要包 remotes/origin
所以這邊需要 aosp/jb-release
$ git push ssh://mickey.acer.com.tw:29418/here/is/my/branch HEAD:refs/for/aosp/jb-release
為了不要每次下指令都指定 user name 也就是
$ repo init -u ssh://my.id@\<SERVER>......
~/.ssh/config
Host \<SERVER>
Port 29418
User XXXX.YYY
跟 Gerrit 裡 Settings -> Profile -> Username 一樣
public class L {
private static boolean BUILDCONFIG_DEBUG = false;
static {
try {
Class<?> c = Class.forName("com.helloworld.BuildConfig");
Field field = c.getField("DEBUG");
BUILDCONFIG_DEBUG = field.getBoolean(null);
} catch (NoSuchFieldException e) {
} catch (ClassNotFoundException e) {
} catch (IllegalArgumentException e) {
} catch (IllegalAccessException e) {
}
}
}
