我知道這個問題被問幾次。這些解決方案中沒有一個是清楚的。讓我解釋一下這個問題。Android outofmemory錯誤位圖大小超過vm 2.3.3中的預算
- 我有一個活動，一次加載4個圖像。
- 我在onResume（）方法中加載圖像。
- 加載時，Activity拋出位圖錯誤。
注意事項。
- 我使用setImageResource（R.drawable.xxxx）方法調用設置圖像，而不是直接繪製位圖。
- 圖像正確縮放。
- 活動在2.3之前的所有仿真器中工作良好，並且在實際設備（Samsung Galaxy 5）中工作得很好
- 錯誤出現在第一次初始化時，並且未激發方向更改事件。
- 圖片尺寸爲800 x 600，平均大小爲15kb（每個）。
讓我知道任何解決方案。另外讓我知道你是否有類似的問題與Android 2.3.3模擬器。

安置自己的onResume代碼，它可能是更容易幫助你。 – 2011-03-21 08:10:52
