Android Studio "IDE error occured" on create new Activity
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.
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.
