Cannot create new activity in android studio

Question

I keep getting an IllegalStateException error in the event log while creating new activity in android studio:

11:27:15 InvalidReferenceException         


        

Answer 1

Comment the code in build.gradle which creates folders in tmp directory and then create the Activity.

After successful creation of activity ,revert back the commented code in build.gradle (Co)

allprojects {
/*String osName = System.getProperty("os.name").toLowerCase();
if (osName.contains("windows")) {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
}*/
repositories {
    jcenter()
}

}

I had the same issue. Visit this Link. https://code.google.com/p/android/issues/detail?id=232076

this happens if you have your project in a different drive other then C: android studio will automatically create a copy of your project (i hope they are cache files) in the C: drive's tmp folder. this folder is the cause for this issue.

try File-> Invalidate Caches/Restart. or just deleted the tmp folder in the c: drive and restart everything and it will work fine.

In the file build.gradle, add

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

sychronize gradle then remove it and synchronize again. This worked for me.

allprojects {
buildDir = "C:/tmp/${rootProject.name}/${project.name}"
repositories {
    jcenter()
}

}
