首先它给出了 ActionBarActivity 无法解决的错误，我尝试通过添加外部 jar 来解决它们，然后这些错误来了

【问题讨论】：

更新您的广告捆绑
@Naveen 你能解释一下吗？
打开sdk管理器并更新android sdk工具
比来自 Eclipse stackoverflow.com/questions/9097163/uninstalling-android-adt 的 uninsatll Adt 和比 insatll adt
已经更新到 23.0.5

标签： java android eclipse build

【解决方案1】：

删除工作区中的 jar 文件即可解决问题

项目名称>libs>android-support-v4

然后去

appcompat_v7>libs>android-support-v4

复制此文件并将其粘贴到您的项目中此过程将帮助您绕过与此问题有关的所有错误

【讨论】：

与这个项目合作得很好:)，但我创建了一个新项目，它给了我 ActionBarActivity 无法解决的错误，总共 9 个错误，我之前通过添加外部 jar 修复了这些错误。我必须为每个项目都这样做还是有解决方案？
这是我用来复制粘贴 jar 文件的每个项目的临时解决方案。后来我更新了我的 ADT 和 SDK，到目前为止我从未遇到过此类问题。更新 ADT 并重新安装 Sdk 就可以解决问题。 这是一个临时的快速修复
你能解释一下我现在应该做什么吗？
只需更新您的 ADT 并安装 sdk 管理器中可用的任何新工具。
永远记住，您必须拥有针对特定 android 版本的 sdk 工具才能进行定位。因此，当您更新到新工具时，请不要删除任何 sdk 工具，并始终使用可用的 sdk 检查您的目标版本工具
