通过检查其他人做了什么

清理的项目重启了eclipse、手机、模拟器、adb和pc。

似乎没有任何帮助，如果有任何帮助，将不胜感激

【问题讨论】：

显示你的清单文件。我在 2 天前遇到了同样的问题，我解决了它
@PiyushKukadiya 它以前工作得很好。添加清单
Datapro 不应位于除 dbd.mygovtnotification 之外的任何其他 package 中，而且 authorities 属性应与 DatabaseProvider 类中定义的 AUTHORITY 常量匹配。
@PiyushKukadiya 不，我的项目中不是只有一个包并且权限匹配

标签： android eclipse

【解决方案1】：

尝试改用这个：

android:name=".Datapro"
android:authorities="dbd.mygovtnotification.datapro"

【讨论】：

@dreamer1989 你确定Datapro 课程在dbd.mygovtnotification 包中吗？

【解决方案2】：

如果在我的情况下没有任何效果（当它以前工作时）考虑创建一个新项目并从旧项目复制文件并更新引用（有些将由 eclipse 自己处理）
