每当我尝试运行AVD时，我的应用程序意外关闭，这就是我得到的错误。这是生成的logcat。它显示FatalException和MemoryException。是AVD错误还是代码错误？请帮忙。
答案您需要了解位图和内存的概念

假设您想要在屏幕上显示刚用相机拍摄的图像。使用以下公式计算所需的总内存：memory_needed_in_bytes = 4 * image_width * image_height;
为什么4？嗯，最常见/推荐的位图配置是ARGB_8888。这意味着对于我们绘制的每个像素，我们需要为内存中的alpha，红色，贪婪和蓝色通道保留8位（1个字节），以便正确显示它。有一些替代品，比如RGB_565配置需要一半的内存而不是ARGB_8888，但是会失去透明度和颜色精度（同时可能会增加绿色）。
让我们假设你有一个全高清屏幕和12万像素摄像头的全新设备。您刚刚拍摄的图片大小为4000x3000像素，显示所需的总内存为：4字节* 4000 * 3000 = 48 MB
对于单个图像，48兆字节的RAM！？好多啊！
现在让我们考虑屏幕分辨率。您试图在具有1920x1080像素的屏幕上显示4000x3000图像，在最坏的情况下（显示图像全屏），您不应分配超过4 * 1920 * 1080 = 8.3 MB的内存。
始终遵循有效显示位图的Android编程技巧：
测量您正在显示图像的视图。相应地缩放/裁剪大图像。仅显示可显示的内容。

另一答案抛出的异常被称为OutOfMemoryError。当（显然）你的内存不足时会发生错误！这是它的文档：

在使用可用平台资源无法满足内存请求时抛出。这样的请求可以由正在运行的应用程序或VM的内部功能来进行。

http://developer.android.com/reference/java/lang/OutOfMemoryError.html
因此，您应该为模拟器分配更多内存。但我认为主要原因是你的应用程序使用了太多内存。你使用超大图像了吗？
另一答案【获得此异常会强制Android应用程序在启动时崩溃】将此ligne添加到清单文件中：
