android - NoClassDefFoundError 与 Kotlin 中的 ?.let{} block

Question

我不明白为什么会出现以下错误:

E/UncaughtException: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/somecompany/someapp/common/glide/GlideWrapper$loadCircularProfileImg$1$1; at com.somecompany.someapp.common.glide.GlideWrapper.loadCircularProfileImg(GlideWrapper.kt:31) at com.somecompany.someapp.main.MainActivity.showSideBarProfPhoto(MainActivity.kt:179) at com.somecompany.someapp.main.MainActivity.onCreate(MainActivity.kt:115) at android.app.Activity.performCreate(Activity.java:6955) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1126) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2927) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3045) at android.app.ActivityThread.-wrap14(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1642) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6776) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1520) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1410)

使用代码:

fun loadCircularProfileImg(ctx: Context, user: User?, targetImageView: ImageView) {

        user?.let {
            // With let getting a NoClassDefFoundError error 😱

            GlideApp.with(ctx)
                    .asBitmap()
                    .load(FirebaseStorage.getInstance().reference.child(it.profImgUrl))
                    .into(object : BitmapImageViewTarget(targetImageView) {
                        override fun setResource(resource: Bitmap?) {
                            // Will add code here
                        }
                    })
        }
    }

但不包括:

fun loadCircularProfileImg(ctx: Context, user: User?, targetImageView: ImageView) {

    if (user != null) {   // With this the code works

        GlideApp.with(ctx)
                .asBitmap()
                .load(FirebaseStorage.getInstance().reference.child(user.profImgUrl))
                .into(object : BitmapImageViewTarget(targetImageView) {
                    override fun setResource(resource: Bitmap?) {
                        // Will add code here
                    }
                })
    }
}

当你调用 loadCircularProfileImg 时用户类被定义，我调用相同的方法并且没有得到如下所示的任何错误......

        loadCircularProfileImg(this,User(),imageview)

我在上面的代码中使用并且没有收到任何错误。
