Android Kotlin - Glide onLoadFailed try another image url on error

Question

I've searched for a solution, but all I found are 100000 questions about how to use a placeholder which is not what I need.

I need Glide to try to load an image from another url if the first one failed.

This is what I've tried:

        fun tryAlternative(){

            val alternativeUrl = func.getMediaUrl(mediaServer) + mediaParameters

            Glide
                .with(context)
                .load(alternativeUrl)
                .listener(object : RequestListener<Drawable> {
                    override fun onLoadFailed(
                        e: GlideException?,
                        model: Any?,
                        target: Target<Drawable>?,
                        isFirstResource: Boolean
                    ): Boolean {
                        return false
                    }

                    override fun onResourceReady(
                        resource: Drawable?,
                        model: Any?,
                        target: Target<Drawable>?,
                        dataSource: DataSource?,
                        isFirstResource: Boolean
                    ): Boolean {
                        holder.picLoadIcon.visibility = View.GONE
                        holder.image.requestLayout()
                        holder.picContainer.layoutParams.height = ViewGroup.LayoutParams.WRAP_CONTENT
                        holder.picContainer.requestLayout()
                        return false
                    }
                })
                .apply(glideOptions)
                .fitCenter()
                // .transform(CutOffLogo())
                .into(holder.image)
        }

        Glide
            .with(context)
            .load(fileUrl)
            .listener(object : RequestListener<Drawable> {
                override fun onLoadFailed(
                    e: GlideException?,
                    model: Any?,
                    target: Target<Drawable>?,
                    isFirstResource: Boolean
                ): Boolean {
                    Handler(Looper.getMainLooper()).postDelayed({
                        tryAlternative()
                    }, 500)

                    return false
                }

                override fun onResourceReady(
                    resource: Drawable?,
                    model: Any?,
                    target: Target<Drawable>?,
                    dataSource: DataSource?,
                    isFirstResource: Boolean
                ): Boolean {
                    holder.picLoadIcon.visibility = View.GONE
                    holder.image.requestLayout()
                    holder.picContainer.layoutParams.height = ViewGroup.LayoutParams.WRAP_CONTENT
                    holder.picContainer.requestLayout()
                    return false
                }
            })
            .apply(glideOptions)
            .fitCenter()
            // .transform(CutOffLogo())
            .into(holder.image)

It works on my test devices which are android 8 and 11.

But some of the users are getting a crash, including api 8 and 11.

This is the error:

How to do this correctly?

you can do this without Handler.

use just this tryAlternative() instead of

Handler(Looper.getMainLooper()).postDelayed({
                        tryAlternative()
                    }, 500)

I know but you think handler is the cause of crash?

Jaber Bin Ahamed Over a year ago

i think . may be

user17027702 Over a year ago

I increased to 5000 to see if I get any crashes but no I don't so I don't think that this is the problem

Jaber Bin Ahamed Over a year ago

without handler you can use Coroutine and you can check your valid image url if url is valid then you through the url to the glide

user17027702 Over a year ago

They are valid, the only problem is 500 error when the server is overloaded. Checking if the image can be loaded before actually doing it will put extra workload to the servers, so it's not an option
