Context - Android

參考：Context都沒弄明白，還怎麼做Android開發？

/**
 * Interface to global information about an application environment.  This is
 * an abstract class whose implementation is provided by
 * the Android system.  It
 * allows access to application-specific resources and classes, as well as
 * up-calls for application-level operations such as launching activities,
 * broadcasting and receiving intents, etc.
 */
public abstract class Context {
    /**
     * File creation mode: the default mode, where the created file can only
     * be accessed by the calling application (or all applications sharing the
     * same user ID).
     * @see #MODE_WORLD_READABLE
     * @see #MODE_WORLD_WRITEABLE
     */

凡是跟UI相關的，都應該使用Activity做為Context來處理

Chrome run Android app ! ?

參考：免模擬器！直接用 Chrome 在電腦跑 Android App！

[ 環境預備 ]
1. 下載 ARChon Custom Runtime
2. 在 Android 安裝 ARChon Packager (Google Play) 或 bpear96/ARChon-Packager
3. 在 Android 執行 ARChon Package ，選擇目標 app ，作出來的檔案會在  /sdcard/ChromeAPKS 的目錄中，AppName.zip

[ 安裝方式 ]
1. 解壓縮 ARChon Custom Runtime ，會是像 vladikoff-archon-6ad1d59d5f1a 的資料夾

2. 在Chrome的網址列輸入 chrome://extensions
勾選「開發人員模式」，並選擇「載入未封裝的擴充功能」，然後將路徑指到步驟1的資料夾


3. 將 AppName.zip 解壓縮，一樣選擇「載入未封裝的擴充功能」，然後將路徑指到 AppName 解完壓縮的資料夾 (有 _locales, vendor 資料夾的上一層)

4. 在Chrome的網址列輸入chrome://apps，就可以看到App圖示。

5. 不一定可以執行
註：FMX 作的 PSC.app 就不能執行

[ twerk ] 將 Android APP (APK 檔案) 包裝成 Chrome 瀏覽器外掛

HTML 常用備忘

[電腦] 特殊字元 HTML 編碼對照表

因為這些是特殊符號，在 html 裡面，要用下列方式代替

• And 符號 ' & ' (ampersand) becomes '&'
• 雙引號 ' " ' (double quote) becomes '"'
• 單引號' ' ' (apostrophe/single quote) becomes '''
• 小於符號' < ' (less than) becomes '&lt;'
• 大於符號' > ' (greater than) becomes '&gt;'
• 空白符號 ' ' (no-break space) becomes '&nbsp;'

常用標籤：

<p>分段

<br /> break 換行 

Blogger 如何設定 Syntaxhighlighter 讓程式碼更容易讀

使用方式，在編輯 html 時，加入

<pre class="brush:cpp;" name="code">
程式碼...
</pre>

cpp 可改成對應的語言
我第一次設定時，程式碼排版異常，最後是把範本砍掉重練，然後照上述方式再次設定，才 OK
