Android Development Environment building

There are two way to building development environment

Option 1. using Android Studio 

               But I don't use that way to running my program

so  ,Let's keep read on
Option 2. using Eclipse + Android SDK Bundle + JDK + Genymotion  1.3.0
there has the SDK intall detail that you need
you also need  Genymobile Plug-In. more detail...

Name: Genymobile

Location: http://plugins.genymotion.com/eclipse

there is the List that we need
Tools
    SDK Tools
    SDK platform
    SDK Build-Tools(If you don't select it , that you'll missing file 'R.java' )
    Genymotion Plug-In
Android 4.3(Optional, Depend on what kind of version that you need )



Now I can coding , Have Fun

布林運算邏輯閘應用

Boolean operators
Operator Operation Operand types Result type Example
not       negation         Boolean Boolean not (C in MySet)
and         conjunction        Boolean Boolean Done and (Total > 0)
or       disjunction          Boolean Boolean A or B
xor exclusive disjunction Boolean Boolean A xor B  

(還有shr、shl 的邏輯位移運用)
(引用於Borland Delphi 7內的F1說明，邏輯閘的說明)
可以用上述的方式來判斷True 或Flase 使用上性能表現比IF判斷值行好很多
例：
 cbFG_QT_CTL.Enabled := (State='Insert') or (State='Query');

上句敘述相同於

IF  (State='Insert') or (State='Query') Then
    cbFG_QT_CTL.Enabled:= True;
else
     cbFG_QT_CTL.Enable:= False;
