叶赫。下次，请将您的 LogCat 转储格式化为“代码”而不是“引用”。至少换行符将在其应有的位置。

也就是说，相关位在这里：

Caused by: java.lang.OutOfMemoryError
11-04 16:50:01.015: E/AndroidRuntime(753): at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)
11-04 16:50:01.015: E/AndroidRuntime(753): at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:483)

解码位图时出现内存不足错误。使其成为较小的位图。

如您的日志所示，错误（异常）的根源是OutOfMemoryError. 位图太大而无法放入内存（即在 Dalvik 托管堆上没有足够的空间供它使用）。此外，加载位图可能需要比存储更多的内存（见下文）。

很可能在您的 Android 4 设备的显示中，您的图像需要比您的 Android 2 设备更多的像素，并且 Android 正在扩大内存中的图像，导致在加载位图时甚至更高的内存消耗.

因此，要么你需要为这种显示类型（即你的 Android 4 设备使用的显示器）缩小你的位图，或者你可以尝试手动加载和设置位图（参见这个关于加载大位图的官方页面）。
