初次快照的例子

接著將你的模擬器操作到你想保留的某個狀態；在這個例子，我們想保留模擬器進到
app
的主要
Activity
時的狀態（如圖
4-5
）。接著關閉這個處理程序，以這例子來說，
也就是點擊左上方的紅色圓圈來關閉視窗。這會需要一些時間（多則一分鐘），因為
程式正在儲存「快照」檔案，使得之後可以很容易地回復至此狀態。

已儲存的快照狀態

下次你開啟模擬器時，可以選擇中間的選項「
Launch from snapshot
」（如圖
4-6
）。
選擇該選項，並點擊「
Launch
」按鈕，此時模擬器並不是從頭開啟（這需要數分鐘），
而是從上個步驟中，關閉模擬器時所儲存的狀態開始。因為模擬器不需要整個重新開
機，所以啟動速度會大大地提升（模擬器開啟至快照狀態約需
10
秒鐘左右）。你會看
到你的模擬器開啟到一樣的地方（如圖
4-7
所示）。
