setContentView中的OutOfMemoryError

Question

我的应用程序中存在一个很难捕获的错误，因为它很少发生（可能每500次我在真实设备上运行应用程序一次）。我在与活动关联的布局中有几个自定义视图。在活动的setContentView（）方法中，我有时遇到OOME，我不明白为什么？

它似乎试图让那个视图膨胀，然后从那里下山。因为问题很少发生，有没有办法可以处理这个错误或者我该如何避免呢？我不明白在这种情况下内存是如何用完的。这是堆栈跟踪

它说错误发生在布局的第738行，这只是一个常规按钮小部件。

更新

尝试充气自定义视图时不会出错。尝试充气常规视图时出错。

Answer 1

当您尝试处理OutOfMemoryError时，似乎会导致Bitmap，从以下几行可以看出：

Caused by: java.lang.OutOfMemoryError
        at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)
        at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:677)
        at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:507)

我强烈建议您阅读有关displaying bitmaps的文章，特别是关于loading large bitmaps efficiently，并检查您的代码是否会这样做。

此外，您可以尝试使用Square的Picasso库，这在使用Bitmaps时会有很大帮助。

更新： 在你的情况下，问题可能是你在布局中使用一些大图像，只是尝试使用较小的图像，看看它是否仍然存在。查看与您类似的this answer。

尝试在清单的应用标记中添加 android：largeHeap =＆＃34; true＆＃34; 。
