我想測試一下我在Eclipse中構建的應用程序。當我在Android 2.3.4上運行的HTC Droid Incredible設備上運行它時，它工作正常。但是，當我在模擬器上運行它時，例如Nexus 7或10.1 WXGA Tablet，它會崩潰。我的目標SDK版本設置爲17，最小版本爲8.爲什麼應用程序在設備上工作，但不是模擬器？應用程序在設備上運行，但在模擬器上崩潰？

看來仿真器內存用完：'所致：java.lang.OutOfMemoryError' – Sam
我能做些什麼來解決這個問題？感謝您的迴應。 –
我不知道Carousel是否是您在自己的代碼中使用的第三方庫，但看起來您正嘗試加載太多太大的圖像和/或圖像。嘗試使用更少或更低質量的圖像。 – Sam
