Question

我有一个Android应用程序，其最低SDK为2.1，我在开发者控制台中获得以下堆栈跟踪：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.versions.MyPhone}: android.view.InflateException: Binary XML file line #2: Error inflating class <unknown>

在具有更新Os的较新设备中不会发生错误。

请帮我解决问题或指出正确的方向。

根据堆栈跟踪中的java.lang.OutOfMemoryError: bitmap size exceeds VM budget消息，看来onCreate（）中打开的视图中的一个图像太大。

这是一个page，有一些指导。主要思想是加载图像的缩小版本。我发现最好还缩小（分辨率，颜色深度等）实际图像文件以最大化加载速度。
