创建位图时出现 java.lang.outofmemoryerror

Question

我收到大图像(png，>30Mb)并为其创建位图。并得到java.lang.OutOfMemoryError。我 try catch 这样的异常:

try {
    Bitmap bmp = BitmapFactory.decodeStream(someStream);
} catch (OutOfMemoryError e) {
    ;
}

使用 2.2 SDK 可以很好地工作。但 2.3 应用程序因未捕获的异常而失败。我不明白，为什么？

谢谢!

你并不是真的要捕获错误:

来自Javadoc :

An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. The ThreadDeath error, though a "normal" condition, is also a subclass of Error because most applications should not try to catch it.

如果您遇到错误，尤其是 OutOfMemoryError，那么基本上已经来不及采取任何措施了。
