java - 在具有更新的 Android 版本的设备中重新构建和运行 Android 程序时出错(androidapi 15 rev1 到 api 15 rev2)

Question

在出现问题之前我执行了以下操作:我在 Android SDK Manager 中运行了更新。它提供了要安装的更新列表，其中包括 SDK 平台工具、SDK 工具的修订版本。下载后我无法自动安装。所以我手动安装，因为这是很多人的问题。我工作区中的大多数应用程序都运行良好，只有少数应用程序除外。

实际问题 我可以成功构建该项目，也可以将其安装在设备中。但是当我单击应用程序的 UI 时，我在设备中收到错误“..进程已意外停止。请重试”在 logcat 中我得到以下内容..

请指导我。我认为某些类文件未被识别。任何建议都可以。谢谢你们:)

com.qualcomm.ar.pl.CameraPreview来自高通的Vuforia库。只需将 QCAR.jar 复制到项目的 libs 目录即可。
