Android 圖片大小超過預算的VM：java.lang.OutOfMemoryError: bitmap size exceeds VM budget

Android 2.3.3         
Eclipse Version: 3.7.0

Activity顯示圖片，部分源代碼：

			// 圖片
			try {
				bitmap = BitmapFactory.decodeFile("/" + sdpath
						+ htc.getBitmap(), opt);
			} catch (Exception e) {
				e.printStackTrace();
			}
			htcImageView.setImageBitmap(bitmap);

發生錯誤原因分析：
bitmap圖片尺寸較大，使用後超過預算的VM；

網上查找到兩種解決辦法：
一種是使用縮略圖，縮小圖片大小

		opt = new BitmapFactory.Options();
		……
		opt.inSampleSize = 2; //使用縮略圖，縮小倍數

 另一種是增加VM大小

		 VMRuntime.getRuntime().setMinimumHeapSize(16 * 1024 * 1024);
		 VMRuntime.getRuntime().setTargetHeapUtilization(0.75f);

但測試無效。

最好的解決辦法：顯示的回收圖片。
