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

removing the build folder redirect code in the gradle file is a workaround.

allprojects {

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

I have been faced that, after I setup my android environment.I already set up and configured everything, but this still occur.After searching a few mins, I found the problem in Logcat,

Then, I know project is missing Build Tool version. You have to give which build tool version you will use to run for project. Go to >> Project Structure , ( Cmd + ; ) in mac. Choose Compile Sdk Version and Build Tools Version, After the gradle build, creating new activity from menu error has been fixed. I hope this will help for you.

Notes : Some of the projects from Github or bitbucket also missing Build Tools version when you cloned and run the project. These are the same errors and this approach can help to solve for them.

Method 1:Just Remove the following code from your app level build.gradle

debug {
            storeFile file('/Users/Razz/Documents/keys/keystore.jks')
            storePassword 'ABC@123'
            keyAlias 'key0'
            keyPassword 'ABC@123'
      }

Method 2: In case, if there are two packages together (kotlin and java)

I was facing the same problem as whenever I create new activity form the activity templates provided by the android studio. Nothing was happening even after Gradle sync completes successfull.

After a long item, I figure out that, java directory name inside my project changed into kotlin somehow. And I supposed Android Studio looking for the java package to create new Activity.

Then, to solve this issue, I follow the below steps:

1. Closed Android Studio
2. Went to the project location up to java directory as ../ProjectName/app/src/main/
3. In this main directory, I had the kotlin directory instead of java.
   So, I just renamed it to java.
4. Then opened the project with Android Studio, and that's all.
5. I created new activity it easily created one as it works before.

Answer 6

I have the same exact problem when trying to create a new activity. IDE Fatal Errors

I was running Android Studio 3.2.1 on Windows 7 Professional. I did not have this problem until I started to switch loading project from different drives - I used to run my projects from F: drive and when I downloaded sample code to C: drive, creating new activities started to give this IDE fatal error.

Got a clue from online sources of a potential issue caused by buildDir path in build.gradle(Project:) shown below;

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

Since my project working directory is in F: drive, I changed the above C: drive to F:

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

With this simple change, I can now create new Activity.

If nothing else works for you I suggest you try this solution.
