Android 1.5 Early Look SDK | Android Developers

 

Emulator for 1.5 SDK

1.5 的EMU 架構大改,要使用1.5的EMU參考說明:

1. 首先要建立一個avd,進入 tools 輸入

> android create avd --name <名稱> --target 2

PS: target 給1為1.1 版、2為1.5版 image

2. 之後會詢問是否自訂硬體項目,如記憶體大小、Camera、GPS ... 等設定。

3. 指定一個avd 並啟動 emu(可使用 android list avds 列出已有的avds)

> emulator @<名稱>

> emulator -avd <名稱>
