(Kotlin) Backend Internal error: Exception during code generation

I am creating a very thorough converter for Android with Kotlin, using the latest Android Studio Canary build and latest Kotlin. I am suddenly getting a compiling error, even thought Android Studio doesn't see any bug in the code, it is complaining about a backend error, so I think my project is good but the Android Studio has a bug?? Please help confirm, this has been a lot of work....

It is complaining about my class MassCalc, which is 6500 lines long, because of many cases for conversion, so maybe that is the problem??

UPDATE The error does not occur when hitting Clean project or Rebuild Project, it occurs when I try to launch it in the emulator!

Very simple code but long file:

https://github.com/Josep-Jesus-Bigorra-Algaba/SuperConverterAndroid

I am experienced with Java but had never seen this exception!

e: java.lang.IllegalStateException: Backend Internal error: Exception during code generation

Any help will be greatly appreciated! Edit: I work from macOS High Sierra but am downloading Linux Mint and will probably try in that to see if the issue persists!

So I split the function in two and the problem got solved. Turns out too much code in one function will bug the compiler! Keep that in mind as a heads up! I can't figure out how to mark as solved :) – Rydder

I had the same problem, because I was using inconsistent version of Anko. With kotlin 1.3.x you have to use this v0.10.8 version of anko or newer.

Is it a dependency? I dont even have it and Im getting that error – Substitution
Yes, this is a dependency conflict, but there might be other causes of this exception. – Trickle
I my case I had this issue with the Kotlin compiler extension for Jetpack Compose. – Ample

For people who are having this issue with jetpack compose add the following lines in build.gradle file 

android {
    ...
    composeOptions {
        kotlinCompilerExtensionVersion "0.1.0-dev04"
    }
}

Could not find method composeOptions() for arguments – Surra
@kishanverma make sure if you are using the proper version of the android studio, it should be the one from the canary channel. – Biretta
Simply try with 'Invalidate Caches/Restart' if you face this during jetpack compose development. – Tammara

Finally I Solved that Issue after Given 3 hours over it and Tried Almost everything

Reason : This Issue may be generate whenever you had taken any XML LAYOUT ID On Java File and you are not using it further. this Garbage XML ID on Java File leads to this Error Named As "Backend Internal error: Exception during code generation Android"

How Do Solve : well, you can find your garbage XML ID from That Error Itself... Just Copy paste your error on Notepad file and read it carefully , you will find XML ID NAME in near by file location in error line number , Thanks :)

I was getting the same error. But in my case, I was writing unit test case and my test case name was too long. like this...

@Test
fun `check invocation of sendMessageWithImages on invocation of sendMessage when isUploadImageValid and reponse is success with no error`() { //test implemantation}

I find this culprit by thinking, what unusual, I am doing here, that we not supposed to do in real android programming. So think like this. If any given solution not work for you. Thanks

I experience the same for UI Test :(. For method names that have more than ~220 characters. – Morbilli

This type of issue usually occurs when the Kotlin has a complex function definition. For example, declaring a class that inherits from AsyncTask. Best solution is try to pull some of this complexity out of the function call.

When I converted my class from Java to Kotlin, this is what converter did to runnable:

runnable = label@ Runnable {
                if (condition) {
                    handler!!.removeCallbacks(runnable)
                    return@label
                }
                if (condition) {
                    handler!!.postDelayed(runnable, 2000)
                    return@label
                }
               //rest of the logic here
            }

This is where the build process was throwing the above error. The reason was return@label

now what I did, 

runnable = Runnable {
                    if (condition) {
                        handler!!.removeCallbacks(runnable)
                        return@Runnable
                    }
                    if (condition) {
                        handler!!.postDelayed(runnable, 2000)
                        return@Runnable
                    }
                   //rest of the logic here
                }

In my case the problem was related to Unit tests like Vishnu Singhal mentioned above. But not with the long test name, instead the problem was that I used quote sign in the test name like this:

fun `fetchUserData @ "by default"`()

The tests were running successfully on developers with MacOS, but for Windows users it was a problem with encoding probably. The solution was to remove quote signs from test name

Simply try with 'Invalidate Caches/Restart' if you face this during jetpack compose development.

As for my case, java.lang.IllegalStateException: Backend Internal error went away when I moved some of the private functions and properties from a big class to other parts of the project. The class wasn't big initially, but I kept adding things without properly organizing.

I was getting the same error in my Android Project. The cause of the error was i taking my recyclerview's id from xml and just pasted the id in my code without apply any kind of property or calling any function on it.

I too was getting the same error in my Android Project. But in my project i was using when inside lambda and i try return not correct type in 4 line 

    private val innChecker: (s: Editable?) -> String? = { s ->
        when {
            CheckUtils.checkZero(s.toString()) -> {
                if (!isBudget) textViewRed
                null
            }
            CheckUtils.checkAllZero(s.toString()) -> getString(R.string.not_all_zero)
            CheckUtils.checkStartZeroZero(s.toString()) -> getString(R.string.two_first_not_zero)
            CheckUtils.checkInn(s.toString(), isBudget, { textViewRedErrorKpp.isEnabled = it }, { textViewRedErrorKpp.setTextToEditText(it) }) -> {
                if (s?.length == 10) mPaymentRecipientPresenter?.tryFindInn()
                when {
                    isHardChecked -> {
                        null
                    }
                    else -> null
                }


            }
            else -> getString(R.string.enter_5_10_12_or_0)
        }

    }

I was facing a similar problem [due to my negligence XD] and got it resolved The line that causing it [i gussesd] was:

        previewJobDialog.jobs_details_save_button

And I corrected it to as I forgot to complete the code for it:

       previewJobDialog.jobs_details_save_button.setOnClickListener {
               //my implementation
            }

I hope it might help someone. [I do not know how anko was involved in it, but after seeing the logs that were saying: During Execution of lambda. I rushed to this line and completed this code and error went away].

This problem went away when I restarted Intellij. It happened for the following:

sealed class ApiException(error: String) : Exception(error) {
    class UpdateException() :
        ApiException("Failed to update")

    class GetException() :
        ApiException("Failed to get")
}
