裁剪android 3.1的图像代码不起作用

这是我的裁剪代码，它在2.2和2.3上运行良好。但它不适用于3.1。请解决这个问题。在V2.3HTC Wildfire S和V3.1Samsung 10.1上测试，提前感谢

我的布局是这样的，你需要在SD卡上有一个图像

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
 >
<TextView  
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content" 
 android:text="@string/summary"
 />
 <Button
 android:id="@+id/btnLaunch"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="Launch Media Gallery"
 />
 <ImageView
  android:id="@+id/imgPhoto"
 android:layout_width="400dip"
 android:layout_height="400dip"
 />
</LinearLayout>

裁剪意图不是公共API的一部分。只有一种解决方案可以保证对所有设备都有效：将裁剪代码集成到您自己的应用程序中。这很容易实现，因为官方android gallery应用程序是开源的：-

如果您不想这样做，您可以通过手动启动三星设备并观察logcat来尝试找出裁剪活动的名称。应该是com.android.sec.gallery3d.app.CropImage

请在您的问题上投入更多精力。“不工作”是没有意义的，请确切地告诉我结果是什么。@蒂姆：裁剪图像后，会出现一个保存图片的进度对话框，它会挂断。进度对话框根本不会运行。
