Loading Images With Fresco From The Internal Storage

Question

I am trying to do:

    val dataSource = imagePipeline.fetchDecodedImage(request, this)
    try {
        dataSource.subscribe(object : BaseBitmapDataSubscriber() {
            override fun onFailureImpl(dataSource: DataSource<CloseableReference<CloseableImage>>?) {

            override fun onNewResultImpl(bitmap: Bitmap?) {
                activity_levels.background = BitmapDrawable(resources, bitmap)
            }

            }, DefaultExecutorSupplier(1).forBackgroundTasks())
        } finally {
            dataSource?.close()
        }
    }

uri = "${directory.absolutePath}/background.jpg"

You can just use

ImageRequest request = ImageRequest.fromFile(yourFile)

to get your image request

However, if you're using the Bitmap directly (like you do), you need to hold on to the CloseableReference and manage the lifecycle for the data, see http://frescolib.org/docs/writing-custom-views.html
