不能运行Android＆QUOT;相机preVIEW＆QUOT;样品 [英] Cannot run Android "Camera Preview" sample

问题描述

我指的样本：<一href=\"http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/Camera$p$pview.html\"相对=nofollow>相机preVIEW 。

该计划只是强制关闭后启动。我也试过，有同样问题的其他相机演示。

The program simply force closes upon start up. I've also tried other camera demos that have the same problem.

我想在我的Nexus One，并与这两个同样的问题在模拟器中运行的样本。我甚至不知道是否应该仿真器能够运行它们。

I'm trying to run the samples on my Nexus One and the emulator with the same problem on both. I'm not even sure if the emulator should be able to run them or not.

我所做的尝试样本是创建一个新的Andr​​oid 2.1update1项目，根据提供的Java文件命名的一切，从复制网址到相机preview.java文件中的Java文件，然后运行它。我应该做别的？

All I did to try out the sample was create a new Android 2.1update1 Project, named everything according to the supplied Java file, copied the Java file from the URL to the CameraPreview.java file, then run it. Am I supposed to do anything else?

任何帮助将是AP preciated。先谢谢了。

Any help would be appreciated. Thanks in advance.
