Android Studio 在创建新活动时出现“IDE 错误”

Question

（见底部更新）

由于 Android Studio 将自身更新到 v3.0，我无法创建新的 Activity。我收到此错误报告对话框，其中显示 2 个错误。我尝试使用不同的项目，尝试清理项目，重新同步 gradle，重新启动计算机，卸载/重新安装 Android Studio，尝试关注 Google 的 project Gradle migration video，但没有任何变化，我不能再工作了......有什么想法吗？

我没有点击“禁用插件”来禁用 Android 支持，因为我不想破坏我不知道的东西。

更新： 在玩的时候，我注意到如果我创建一个新项目就不会出现问题。它只发生在现有项目上。

Answer 1

我最终通过将旧版本降级到 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，问题最终只是 项目 Gradle 文件中的那一行：

buildDir = "C:/tmp/${rootProject.name}/${project.name}"

如果您删除该行，那么一切都会正常进行。另一个解决方案包含其他更改，但不需要它们来解决问题。

Answer 2

无需降级。只需确保您：

(a) 应用 gradle 插件 3.0.0，(b) 将 repo 引用添加到“google()”，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()
    }
}

在这些步骤之后，我可以向现有项目添加新活动。

Answer 3

我通过更改项目的 JDK 来修复我的问题。

WINDOWS 10： 安装 Android Studio(AS) 后，默认的 JDK 将是 embedded JDK，它随 AS 包一起提供。您只需要将 JDK 更改为系统中安装的 JDK。

步骤：

1. 右击“app”文件夹
2. 选择“打开模块设置”
3. “SDK 位置”
4. 取消选中“使用嵌入式 JDK”
5. 选择系统中JDK的安装文件夹EX：C:\Program Files\Java\jdk1.8.0_144

之前

Embedded JDK

之后

Installed JDK

希望对你有帮助:)

Answer 4

尝试这样做 文件 > 使缓存无效/重新启动 > 无效并重新启动。

Answer 5

我遇到了同样的问题，因为我从欢迎屏幕打开了一个克隆项目，而不是从“打开现有项目”打开它。

所以只需关闭您的项目，然后从菜单中选择“打开现有项目”，然后打开您的项目，您的问题就会得到解决。

Answer 6

如果您使用 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 输出中发出警告，指出它们是不同的，所以请保持 I！

Answer 7

1. 从C:\Users\Fateh Hayat\AppData\Local\Android\Sdk找到SDK
2. 找到文件夹platform-tools
3. 将此文件夹重命名为platform-tools old
4. 从Here下载文件
5. 在此下载后第一个包含 7.16mb 的 windows 链接文件
6. 将此文件复制并粘贴到 SDK 文件夹后
7. 然后进入Android Studio，选择Tools>sdk manager>sdk tools>android sdk platform-tools
8. 点击Apply
9. 重启 Android Studio...

Answer 8

对我来说解决了这个问题：文件 >> 使缓存无效/重新启动...并选择 无效并重新启动
