android crosswalk new for file upload、camera test

1、build.gradle

repositories {
maven {
url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
}
}

compile 'org.xwalk:xwalk_core_library:18.48.477.13'

2、active_main.xml

<org.xwalk.core.XWalkView android:id="@+id/activity_main"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</org.xwalk.core.XWalkView>

3、MainActivity.java

mXWalkView = (XWalkView) findViewById(R.id.activity_main);
mXWalkView.load("https://blueimp.github.io/jQuery-File-Upload/", null);

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
mXWalkView.onActivityResult(requestCode, resultCode, data);
}

4、AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

web app javascript hyper app basic

基本上 codova phonegap都是用webview裡面的addJavascriptInterfac 指定@JavascriptInterface 的java method，間接呼叫回傳資料，達到和原生溝通

codova phone 等等都是包好，讓使用者方便使用，而且共同開發，讓呼叫回傳 android 多版本能正常

ionic、titanic、react native 等等為了在web app上速度更快或是對應呼叫回傳時，開發速度更快

用CrossWalk包的話，可以肯定是最新的chrome，保證在操作上的正常！但app會非常的肥大~~

再不然就不能事先說明android 5以上才能存取 camera, file upload

[轉]怎麼知道 SEO (關鍵字) 成效如何?

https://cola.workxplay.net/how-to-know-seo-is-working/

快查 SEO 成效

– Chrome 請登出 Google 帳號
– 請用無痕模式

你可以在 Google 查詢 site:你的網址
確認你的頁面被 Google 收錄(建立索引 / index)了沒.

(已經被收錄的網址)

[轉]SMO

FaceBook : Open Graph tags
https://developers.facebook.com/docs/sharing/webmasters#markup
最常見的 FB og /社群標籤，直接影響轉貼、分享於 FB 上的內容

小乾貨：有時修改了 og tag 內容，但是 FB 的分享畫面總是出現舊資料，這時可以試試 https://developers.facebook.com/tools/debug/ ，請 FB 重新抓取指定網址的資料。

=====

Twitter card info
https://dev.twitter.com/cards/types/summary個人愛用，雖然近期使用人數大減，但他的好處和優點很難用文字說明 XD ，除了 card info 的標籤官網也指出：我們也吃 og 標籤

Google Plus / Google +
https://developers.google.com/+/web/snippet/你以為 Google plus 沒人用，那就虧大了！Google 的搜尋結果頁超愛這味的！
上面的網址內也有提供產生器，讓非工程師也能簡單使用。

MicroData JSON-LD
https://developers.google.com/schemas/formats/json-ld?hl=zh-TW這算是比較工程師層面的，把內容丟給你家工程師看吧

由入門的 MicroData (http://schema.org/) 延伸到較進階的 JSON-LD

====================

Google 提供的 https://developers.google.com/structured-data/testing-tool/ ，他能驗證、檢驗你設定的 tag 有沒有生效、正確

強大的 http://smo.knowem.com/ ，他能將所有常用、相關的 tag 分類列出，並且還能告訴你缺少了哪些

較可惜的 https://www.similarweb.com/website/，他可以取得目標網站的各種資料，關鍵字、連入/連出網站等，缺點就是想要更多資訊，就需要升級付費功能
