我的应用程序中有一个很难捕捉的bug，因为它很少发生（可能每500次我在实际设备上运行一次应用程序）。我在布局中有两个与活动相关联的自定义视图。在活动的setContentView（）方法中，我有时会遇到OOME，我不知道为什么？
它似乎在试图夸大这一观点，然后从那里走下坡路。因为这个问题很少发生，我有办法处理这个错误吗？或者我怎样才能避免它？我不明白在这种情况下记忆是如何耗尽的。这是堆栈跟踪

它说错误发生在布局的738行，这只是一个普通的按钮小部件。
更新
错误不在于试图膨胀自定义视图。错误在于试图为常规视图充气。
最佳答案
您的OutOfMemoryError似乎是在尝试处理Bitmap时引起的，可以从以下几行看出：
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)
我强烈建议您阅读这篇关于displaying bitmaps的文章，特别是关于loading large bitmaps efficiently的文章，如果是，请检查您的代码。
此外，您还可以尝试使用一个逐平方的Picasso库，这在使用
Bitmaps时有很大帮助。更新：
在你的例子中，问题可能是你在布局中使用了一些大的图像，只是尝试使用较小的图像，看看它是否仍然会存在。查看this answer与您的类似。
