Android Studio "IDE error occured" 正在创建新的 Activity
Android Studio "IDE error occured" on create new Activity
（见底部更新）
自从 Android Studio 将自身更新到 v3.0，我无法制作新的 Activity.. 我收到此错误报告对话框，显示 2 个错误。我尝试了一个不同的项目，尝试清理项目，重新同步 gradle，重新启动我的计算机，uninstalling/reinstalling Android Studio，尝试遵循 Google 的 project Gradle migration video 但是什么都没有改变，我不能再工作了...有什么想法吗？
我没有单击 "disable plugin" 来禁用 Android 支持，因为我不想破坏我不知道的东西。

更新：
在玩耍时，我注意到如果我创建一个新项目，问题就不会发生。它只发生在现有项目上。
尝试这样做
文件 > 无效 Caches/Restart > 无效并重新启动。
我最终通过获取旧版本降级到 2.3.3：
https://developer.android.com/studio/archive.html
更新：
在使用此处发布的解决方案进行测试后，问题最终只出现在 项目 Gradle 文件 :
中的那一行
buildDir = "C:/tmp/${rootProject.name}/${project.name}"
如果删除该行，则一切正常。另一个解决方案包含其他更改，但不需要它们来解决问题。
无需降级。只需确保您：
(a) 应用 gradle 插件 3.0.0，(b) 添加对 "google()" 的 repo 引用，以及 (c) 从项目 gradle 文件中删除 buildDir 代码.
allprojects {
//String osName = System.getProperty("os.name").toLowerCase();
//if (osName.contains("windows")) {
// buildDir = "C:/tmp/${rootProject.name}/${project.name}"
//}
repositories {
google()
jcenter()
}
}
完成这些步骤后，我可以向现有项目添加新的 activity。
我通过更改项目的 JDK 修复了我的问题。
WINDOWS10:
安装 Android Studio(AS) 后，默认 JDK 将 embedded JDK 随 AS 包一起提供。您只需要将 JDK 更改为系统中安装的那个即可。
步骤：
- 右键单击 "app" 文件夹
- Select "Open Module Settings"
- "SDK Location"
- 取消选中 "Use embedded JDK"
- Select你系统JDK的安装文件夹EX: C:\Program Files\Java\jdk1.8.0_144
之前
Embedded JDK
之后
Installed JDK
希望对您有所帮助:)
我遇到了同样的问题，因为我从欢迎屏幕打开了一个克隆的项目，而不是从 "Open an existing project" 打开它。
所以只需关闭您的项目，然后从菜单 select "Open an existing project" 然后打开您的项目，您的问题就会得到解决。
如果您使用的是 Kotlin，请确保 build.gradle 中的 ext.kotlin_version 与您的插件版本匹配。对我来说，它还在 gradle 输出中给出了警告，指出它们是不同的，所以请保留 I！
- 从
C:\Users\Fateh Hayat\AppData\Local\Android\Sdk 中查找SDK
- 查找文件夹
platform-tools
- 将此文件夹重命名为
platform-tools old
- 从Here
下载文件
- 下载完成后，第一个 link 文件 windows 包含 7.16mb
- 将此文件复制粘贴到SDK文件夹后
- 然后转到 Android Studio，select 工具>sdk 管理器>sdk 工具>android sdk 平台工具
- 点击
Apply
- 重新启动 Android Studio...
对我来说解决问题的方法是：文件 >> 无效Caches/Restart... and select 无效并重启
对我来说，re-running Gradle 构建才有效。只需按 Ctrl+F9 或单击 make project 按钮并等待一段时间，直到 Gradle 构建完成。繁荣，错误已修复！它对我有用，我希望它对仍然面临问题的人有用。

(These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??

更新： 在玩耍时，我注意到如果我创建一个新项目，问题就不会发生。它只发生在现有项目上。
尝试这样做 文件 > 无效 Caches/Restart > 无效并重新启动。
我最终通过获取旧版本降级到 2.3.3： https://developer.android.com/studio/archive.html
更新：
在使用此处发布的解决方案进行测试后，问题最终只出现在 项目 Gradle 文件 :
buildDir = "C:/tmp/${rootProject.name}/${project.name}"
如果删除该行，则一切正常。另一个解决方案包含其他更改，但不需要它们来解决问题。
无需降级。只需确保您：
(a) 应用 gradle 插件 3.0.0，(b) 添加对 "google()" 的 repo 引用，以及 (c) 从项目 gradle 文件中删除 buildDir 代码.
allprojects {
//String osName = System.getProperty("os.name").toLowerCase();
//if (osName.contains("windows")) {
// buildDir = "C:/tmp/${rootProject.name}/${project.name}"
//}
repositories {
google()
jcenter()
}
}
完成这些步骤后，我可以向现有项目添加新的 activity。
我通过更改项目的 JDK 修复了我的问题。
WINDOWS10: 安装 Android Studio(AS) 后，默认 JDK 将 embedded JDK 随 AS 包一起提供。您只需要将 JDK 更改为系统中安装的那个即可。
步骤：
- 右键单击 "app" 文件夹
- Select "Open Module Settings"
- "SDK Location"
- 取消选中 "Use embedded JDK"
- Select你系统JDK的安装文件夹EX: C:\Program Files\Java\jdk1.8.0_144
之前
Embedded JDK
之后
Installed JDK
希望对您有所帮助:)
我遇到了同样的问题，因为我从欢迎屏幕打开了一个克隆的项目，而不是从 "Open an existing project" 打开它。
所以只需关闭您的项目，然后从菜单 select "Open an existing project" 然后打开您的项目，您的问题就会得到解决。
如果您使用的是 Kotlin，请确保 build.gradle 中的 ext.kotlin_version 与您的插件版本匹配。对我来说，它还在 gradle 输出中给出了警告，指出它们是不同的，所以请保留 I！
- 从
C:\Users\Fateh Hayat\AppData\Local\Android\Sdk中查找SDK
- 查找文件夹
platform-tools - 将此文件夹重命名为
platform-tools old - 从Here 下载文件
- 下载完成后，第一个 link 文件 windows 包含 7.16mb
- 将此文件复制粘贴到SDK文件夹后
- 然后转到 Android Studio，select 工具>sdk 管理器>sdk 工具>android sdk 平台工具
- 点击
Apply - 重新启动 Android Studio...
对我来说解决问题的方法是：文件 >> 无效Caches/Restart... and select 无效并重启
对我来说，re-running Gradle 构建才有效。只需按 Ctrl+F9 或单击 make project 按钮并等待一段时间，直到 Gradle 构建完成。繁荣，错误已修复！它对我有用，我希望它对仍然面临问题的人有用。
