Android 內存暴減的秘密

通常來說不管是做什麼性能優化，逃不出性能優化3步曲：

1. 找到性能瓶頸

2. 分析優化方案

3. 執行優化


上述三步看似第三步最能決定優化結果，而事實上，從筆者的幾次性能優化經歷來看，找到瓶頸確佔據了絕對的影響力！

●  能否找到瓶頸意味著優化做不做的下去。

●  找到的瓶頸性能越差意味著優化效果越明顯。

●  找到的瓶頸越多同樣意味著優化效果越好。

[API 19] ApiDemo Build Error : android.support.v4"

ApiDemo Build Error

import android.support.v4.print.PrintHelper;   <=  Build Error

google " add library eclipse android.support.v4"


Project > Properties > Java Build Path > Libraries
Add External jars

<sdk>\extras\android\support\v4\android-support-v4.jar
e.g.  C:\Users\KOD\android-sdks\extras\android\support\v4\android-support-v4.jar

Done

http://developer.android.com/tools/support-library/index.html

If you are including the v4 support and v7 appcompat libraries in your application, 

you should specify a minimum SDK version of "7" (and not "4"). 

The highest support library level you include in your application determines the lowest API version in which it can operate.

Java Source Code Attachment in Eclipse

How to change Eclipse's “associated source” for debugging?

In the package explorer, where the jar is in a library (JRE, Maven dependencies, etc...);
right click => properties => java source attachment.

Alternately in the project properties => Java build path => Library tab => select the jar => edit.

http://www.cavdar.net/2008/07/14/3-ways-of-jdk-source-code-attachment-in-eclipse/     (for eclipse 3.4)
as for eclipse 4.3.1, only method 1 works.

打開某class   (e.g. import android.app.ActionBar; )
會跳出 source file not found錯誤訊息的那頁 有個可以讓你設定的按鈕
"change attached source"

External Folder
choose
<sdk>\sources\android-19

=========

不必再用External File (add external jar)

即以下都不必做  (不必再另外下載jar檔)

I usually refer this site for the android source code.
