自定義
mkdir device/mcpyname/mphone|mtvtable|mcar
進入目錄后(添加第一個腳本文件)
vim vendorsetup.sh
添加
add_lunch_combo projectname-user
add_lunch_combo projectname-userdebug
add_lunch_combo projectname-eng
add_lunch_combo 是build/envsetup.sh聲明的函數
添加的關鍵文件有 (根目錄下 device/mcpyname/mphone|mtvtable|mcar)
1.AndroidProducts.mk ( 設定PRODUCT_NAME，在source build/envsetup.sh，lunch后顯示PRODUCT_NAME )
2.AndroidBoard.mk
