Error running MyActivity: Gradle project sync failed. Please fix your project and try again
提问by Jaskey
I am new to Android Studio and I have just created a new project with only one Activity with fragments(Android studio created that), and when I ran the MyActivity.java , error occurs:
我是 Android Studio 的新手,我刚刚创建了一个只有一个 Activity 和 Fragment 的新项目(Android Studio 创建的),当我运行 MyActivity.java 时,发生错误:
Error running MyActivity: Gradle project sync failed. Please fix your project and try again.
Nothing more in my event log.
我的事件日志中没有更多内容。
I have no idea why it is, and This linkdid not helps.
我不知道为什么会这样,这个链接没有帮助。
One clue is that Gradle project sync in progress is flowing all the time , just after I restart the Studio.
一个线索是正在进行的 Gradle 项目同步一直在流动,就在我重新启动 Studio 之后。

- Goto File -> Invalidate caches / Restart
- Shutdown Android Studio
- Rename/remove .gradle folder in the user home directory
- Restart Android Studio (It will download gradle metadata and data)
- Gradle build succeed
- Rebuild project
- Done
- 转到文件 -> 使缓存无效/重新启动
- 关闭 Android Studio
- 重命名/删除用户主目录中的 .gradle 文件夹
- 重新启动 Android Studio(它将下载 gradle 元数据和数据)
- Gradle 构建成功
- 重建项目
- 完毕

The exact same error message also pops up if there is a syntax-error inside your AndroidManifest.xml file. So if the above won't work - which it didn't for me - then check the AndroidManifest.xml syntax. That will save you thousands of frustrating hours.
如果 AndroidManifest.xml 文件中存在语法错误,也会弹出完全相同的错误消息。因此,如果上述方法不起作用 - 这对我来说不起作用 - 然后检查 AndroidManifest.xml 语法。这将为您节省数以千计令人沮丧的时间。
