Android SQLite
在寫 SQLite 與實做 CRUD 介面教學的初稿。為了講清楚整個觀念竟然花了 5 章,還不包含講 ContentProvider,估計 ContentProvider 也要再加 2、3 章才夠 XD
一個 NotePad 背後需要好多技術,為什麼其他人寫教學可以把 SQL+CRUD+Content Provider 合在一起一篇講完呀?Android 初學者每個都這麼強大嗎?Orz
還是大家都太著急,希望有捷徑可走?
要不是我這個人太笨,Java 技巧太虛了,就是其他教的人都太聰明吧。
Flash demo on Android
以後網頁上的 Flash 廣告或以 Flash 開發的遊戲也可以在 Android 上執行了。
Jythonroid: Jython runs successfully on Android Emulator
What is jythonroid
Jythonroid is a project for porting jython on Android platform. Created by ClassFoo.
Jythonroid is for console-only at this time. It means oneday Android has console/terminal app in device, you could use jython on real android phone. (or please point me if there's an exist console/terminal app for Android)
Jythondroid was worked on m5-build but outdated when 1.0 SDK comes out. Now Jythonroid (branch) works on 1.0 SDK & Android Emulator again. Since there's no GUI yet, you could checked out the code, run the emulator(install in emulator), and use adb shell on PC to try jythonroid.

$ adb shell
dalvikvm -classpath org.classfoo.apk org.python.util.jython

移動網路的進展
畢業以後用了許多時間玩了各種技術,發現還是無法忘懷小丑魚 (NEMO,Network Mobility)。 我的熱情可能還是在網路移動技術上吧。
花了些時間察看 NEPL (NEMO Platform for Linux) HOWTO 以了解最近 Mobile IPv6 的更新情況,發現現在 MIPv6 for Linux (MIPL) 專案似乎已經被 USAGI 接管了。新的專案名稱叫 UMIP,並直接包含 NEMO 的功能。
(以後待續...)
