無法獲取helloWorld加載到AVD

我的Helloworld教程示例構建並運行得很好，除非它不顯示文本（即加載應用程序）。我唯一看到的是模擬器（目標2.2 API級別8）只有其中的「Android」。然後仿真器在一段時間內顯示鎖定屏幕。這裏是從控制檯輸出無法獲取helloWorld加載到AVD

[2010-09-20 10:38:27 - HelloAndroid] Installing HelloAndroid.apk...

我退出模擬器後，我得到以下錯誤。

此外，有沒有一種方法來捕獲從仿真器即將運行時CMD窗口中運行的TEXT？

提供一些代碼，請之前！你有沒有正確設置模擬器？捕獲什麼意思？我假設你使用eclipse。在Eclipse中，只要您不刪除日誌，就會保存日誌。但有一個按鈕可以導出日誌。安裝HelloAndroid.apk ...是否成功？ – 2010-09-21 05:17:20

只需按下模擬器中的菜單按鈕即可。

這是你的控制檯有什麼要說的，以任何方式你的Eclipse是無法最小sdkversion添加到您的清單

WARNING: Application does not specify an API level requirement!

只需添加以下代碼到你的清單文件，並檢查它是否有效或不，還關閉所有打開的XML文件，運行應用程序

<uses-sdk android:minSdkVersion="8" />

試試看，說會發生什麼
