(See update at the bottom)
Since Android Studio updated itself to v3.0, I can't make a new Activity.. I get this error reporting dialog showing 2 errors. I tried with a different project, tried cleaning the project, resyncing gradle, restarting my computer, uninstalling/reinstalling Android Studio, tried following Google's project Gradle migration video but nothing changes and I can't work anymore... Any ideas?
I didn't click "disable plugin" to disable Android Support as I don't want to break something I don't know about.
Details of first error message:

UPDATE: When playing around, I noticed that the problem doesn't occur if I create a new project. It only happens on existing projects.
回答1:
I ended up downgrading to 2.3.3 by getting the old version there: https://developer.android.com/studio/archive.html
UPDATE:
After testing with the solution posted here, the problem ended up being only that line in the project Gradle file:
buildDir = "C:/tmp/${rootProject.name}/${project.name}"
If you remove that line then everything will work. The other solution contains additional changes but they are not needed to fix the problem.
回答2:
No need to downgrade. Just ensure you:
(a) apply gradle plugin 3.0.0, (b) add the repo references to "google()", and (c) remove the buildDir code from your project gradle file.
allprojects {
//String osName = System.getProperty("os.name").toLowerCase();
//if (osName.contains("windows")) {
// buildDir = "C:/tmp/${rootProject.name}/${project.name}"
//}
repositories {
google()
jcenter()
}
}
I could add a new activity to an existing project after these steps.
回答3:
I fixed mine by changing the JDK for my project.
WINDOWS 10: Upon installing Android Studio(AS), the default JDK will be embedded JDK which comes along with the AS package. You just need to change the JDK to the one that is installed in your system.
Steps:
- right click "app" folder
- Select "Open Module Settings"
- "SDK Location"
- Uncheck "Use embedded JDK"
- Select the installation folder of the JDK in your system EX: C:\Program Files\Java\jdk1.8.0_144
Before
Embedded JDK
After
Installed JDK
I hope it helps :)
回答4:
Try doing this File > Invalidate Caches/Restart > Invalidate & Restart.
回答5:
I was having the same issue because i opened a cloned project from the welcome screen rather than opening it from "Open an existing project".
So just close your project and then from the menu select "Open an existing project" and then open your project and your problem will be solved.
回答6:
If you are using Kotlin, make sure that the ext.kotlin_version inside your build.gradle matches the version of your plugIn. For me it also gave a warning in the gradle output that those were different, so keep an I on that!
回答7:
- Find SDK from
C:\Users\Fateh Hayat\AppData\Local\Android\Sdk - Find folder
platform-tools - Rename this folder to
platform-tools old - Download file from Here
- After this download first link file for windows that contains 7.16mb
- After this file copy and paste in SDK folder
- Then go to Android Studio, select Tools>sdk manager>sdk tools>android sdk platform-tools
- Click
Apply - Restart Android Studio...
