第一次編譯時，設定android SDK：
F:\RAD Studio XE6\PlatformSDKs\adt-bundle-windows-x86-20131030\sdk
F:\RAD Studio XE6\PlatformSDKs\android-ndk-r9c
C:\Program Files\Java\jdk1.7.0_40
SDK更新代理
XE6 不支持JStringToString、StringTojString、StrToJURI：use Androidapi.Helpers
//Splash Image
Delphi XE5，XE6，XE7編譯的程序在Android下啟動會有一段時間黑屏，以前需要用Java擴展Activity增加Splash顯示，
現在Delphi XE7增加了Splash Image顯示功能了。
步驟：
1.鼠標右鍵點擊工程，選擇Options，
2.進入Application分頁
3.勾選Include Splash Image
4.選擇您的Splash Image文件
5.設置Splash Tile mode和Splash Gravity
Splash Tile Mode
disabled -按圖片尺寸大小顯示，顯示位置有Splash Gravity設置
clamp - 圖形邊框適應屏幕大小
repeat - 屏幕水平，豎立方向重復填充滿Splash Image
mirror - 跟repeat差不多，圖片是鏡像的。
Gravity 設置比屏幕小的圖片在屏幕中的位置，只有當Splash Title Mode為Disable時有效,
參數大家一看便知道什麼意思了，我就不提了。
帶文件發布
菜單project ->deployment->然後點擊增加按鈕，選擇中sqlite數據test.s3db,
remote path填寫assets\internal\
應用顯示中文名（工程不能為中文否則會編譯出錯）
菜單project ->Option->Version Info->label
FMX.Consts漢化（需要更改單元）

TBluetoothManager是藍牙管理器，用於藍牙設備管理，包括發現藍牙設備，獲取配對設備，處理遠程配對請求等功能
TBluetoothDeviceList是藍牙設備列表，TBluetoothDeviceList = class(TObjectList),可以通過TBluetoothManager.GetPairedDevices獲得配對設備列表
TBluetoothAdapter本機藍牙設備，實現配對、取消配對等功能，可通過TBluetoothManager.CurrentAdapter得到當前藍牙設備
TBluetoothDevice遠端藍牙設備，每個遠端設備可以提供若干個服務（TBluetoothService），
TBluetoothService遠端藍牙設備服務，包括服務名和UUID
TBluetoothServiceList服務列表 = class(TList
);可通過TBluetoothDevice.GetServices獲得遠端設備服務列表
TBluetoothSocket藍牙通訊套接字,通過TBluetoothDevice.CreateClientSocket(StringToGUID(ServiceGUI), True/False)創建
