我有2项活动 Activity A = GameActivity使用PhotoTask.class的一个实例，它扩展了AsyncTask并用于获取和保存图片。保存图片后，我启动Activity B = ShareActivity。
当我拍照并且不改变方向时，活动B被调用并且一切正常。然而，如果我改变屏幕的方向来拍摄照片（我从肖像传递到风景）我拍照时出错（活动B没有开始）。
我甚至在我的代码中评论了我的位图图像，但仍然有位图错误！ 什么是奇怪是如果我在我的代码中注释ImageView5（没有特别做什么）并保留我的位图，我没有错误。问题似乎来自这个ImageView，但我无法解释它
我在清单中添加了configChanges：orientation，回收我的bnitmaps，使用了一个活动的WeakReference而不是acitvity本身作为PhotoTask中的变量，试图用eclipse内存分析器（Android: Detecting leaks with Eclipse Memory Analyzer）查看内存泄漏但不明白为什么我有这些错误
我真的经常搜索，我变得非常绝望，所以如果你能帮助我，那就太好了

拍摄照片后，您需要使用“图像调整大小”来调整图像大小，然后传递图像以及所需的新宽度和高度。 如果跟踪clcik DDMS上的堆然后在设备列表上的evice并调试代码，您将看到图像的大小增加exra普通 请查看官方文件中的Loading large bitmap Efficiently
阅读后，您可以尝试以下代码，您的问题将得到解决
/** getResizedBitmap method is used to Resized the Image according to custom width and height
* @param image
* @param newHeight (new desired height)
* @param newWidth (new desired Width)
* @return image (new resized image)
* */
public static Bitmap getResizedBitmap(Bitmap image, int newHeight, int newWidth) {
int width = image.getWidth();
int height = image.getHeight();
float scaleWidth = ((float) newWidth) / width;
float scaleHeight = ((float) newHeight) / height;
// create a matrix for the manipulation
Matrix matrix = new Matrix();
// resize the bit map
matrix.postScale(scaleWidth, scaleHeight);
// recreate the new Bitmap
Bitmap resizedBitmap = Bitmap.createBitmap(image, 0, 0, width, height,
matrix, false);
return resizedBitmap;
}

正如乌斯曼库尔德所说，你将（完整）图像加载到内存中，并在内存中创建它的副本。这使用了大量的内存。他引用的文件指出：
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(getResources(), R.id.myimage, options);
int imageHeight = options.outHeight;
int imageWidth = options.outWidth;
String imageType = options.outMimeType;
在这些行中的任何一行都会发生内存不足，而不是在imageview中设置图像
Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
Bitmap mutableBitmap = bitmap.copy(Bitmap.Config.ARGB_8888, true);
如果使用此android，则不会将整个位图加载到内存中，而是缩小版本。 阅读文档，您的错误肯定会消失。
上面的代码只会解码边界。 documentation解释了如何使用它。请参阅“将缩小版本加载到内存中”一章如何正确实现
