Glide: java.lang.NoClassDefFoundError when creating anonymous object in Kotlin Lambda

Created on 28 Feb 2018  路  12Comments  路  Source: bumptech/glide


Glide Version: 4.5.0, also occurs with 3.8.0

Minimal working example:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</android.support.constraint.ConstraintLayout>

import android.graphics.Bitmap
import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import com.bumptech.glide.Glide
import com.bumptech.glide.request.target.BitmapImageViewTarget
import kotlinx.android.synthetic.main.activity_main.*

class Changes(private val activity: MainActivity, private val url: String?) {
    fun show() {
        url?.let {
            Glide.with(activity).asBitmap().load(url)
                .into(object : BitmapImageViewTarget(activity.myImageView) {
                    override fun setResource(resource: Bitmap?) {
                        activity.myImageView.setImageBitmap(resource)
                    }
                })
        }
    }
}

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        Changes(
            this,
            "https://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/SNice.svg/1200px-SNice.svg.png"
        ).show()
    }
}

Seems to work fine if I don't load it into an anonymous class but rather directly into an ImageView. Error thrown is this:

It seems to be related to kotlin inline fun
for example:
when I use let fun like this , will get java.lang.NoClassDefFoundError

mBinding?.let {
            GlideApp.with(context)
                    .asBitmap()
                    .load(data.image_urls.original)
                    .into(object : CustomTarget<Bitmap>() {
                        override fun onLoadCleared(placeholder: Drawable?) {
                            viewModel.cover = null
                        }

                        override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                            viewModel.cover = resource
                            it.cover.setImageBitmap(resource)
                        }

                    })
        }

but if I remove let fun like this锛宔verything is ok

if (mBinding != null) {
            GlideApp.with(context)
                    .asBitmap()
                    .load(data.image_urls.original)
                    .into(object : CustomTarget<Bitmap>() {
                        override fun onLoadCleared(placeholder: Drawable?) {
                            viewModel.cover = null
                        }

                        override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                            viewModel.cover = resource
                            mBinding.cover.setImageBitmap(resource)
                        }

                    })
        }

Finally, I wish anyone tell me what cause it

I don't think this is Glide related, it looks like there's some issue with your build where required classes aren't included. Maybe proguard?

StackOverflow might be a better place for this question.

That's what I thought at first, but in this test project, Proguard isn't enabled. However, if I add:

 debug {
            debuggable true
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

so that Proguard _is_ enabled, I actually get a compile time error with Proguard failing to find the referenced class. I also thought it was a Kotlin issue at first but if I lift the object creation out into a separate function:

         runOnInterface(object : BitmapImageViewTarget(activity.myImageView) {
                override fun setResource(resource: Bitmap?) {
                    activity.myImageView.setImageBitmap(resource)
                }
            })
...
fun runOnInterface(obj: BitmapImageViewTarget) {
        Glide.with(activity).asBitmap().load(url)
            .into(obj)
    }

It doesn't crash. Not sure the cause of this issue and where I should file. Should I make a ticket under Kotlin's tracker?

delete app/build and clear project.

I have the exact same issue, cleaning the project does not help :(

This work around fixed the issue for me

Did you use inline fun like mine?
