Answer 1

the problem was in Manifest.xml security issuess. solution : adding android:usesCleartextTraffic="true" to the application section

Answer 2

Try this applyDefaultRequestOptions Method for Center crop of the image

Glide.with(mContext)
                .applyDefaultRequestOptions(RequestOptions().centerCrop())
                .load(imageUrl)
                .placeholder(R.drawable.ic_baseline_add_business_24)
                .into(target!!)
