我正在为一个名为“Layar”的软件的客户端编写应用程序。尝试从Android Market安装此软件时，我收到以下信息：“安装错误;未知原因-17。”我和一位同事一起搜索了网络，以获取信息和解决方案，但没有发现任何用处。
正在使用的硬件我正在为几款HTC Sapphire 32B（HTC Magic）开发应用程序。这些手机目前正在运行自定义Android操作系统。据我所知，操作系统只是由于蓝牙正常操作的修改而“自定义”。 编辑：手机的操作系统是Android 2.1。
stackoverflow可以帮助这是尝试下载程序时的相关输出（编辑后删除不必要的行）：

我能看到的最重要的事情是：
E/PackageManager( 75): Package com.layar requires unavailable feature android.hardware.camera; failing!
I/vending ( 1849): com.android.vending.AssetDownloader$DownloadManagerBroadcastReceiver$MyPackageInstallObserver.packageInstalled(): Package install from content://downloads/download/19 failed: Unknown reason -17
但是，相机 可用且 可用。有谁知道这可能导致什么？错误编号-17是否与相机问题有关？有没有人甚至遇到过这个？无论如何，如果您能提供帮助，请提前感谢您的时间和感谢！

我要尝试的第一件事是将应用程序下载到非自定义ROM设备，看看这里发生了什么。也许自定义rom以某种方式破坏了硬件报告。
