@SuppressLint("StaticFieldLeak")

class FetchImageFromInternet(var imageView: ImageView) : AsyncTask

init {
// Toast.makeText(applicationContext, "Please wait, it may take a few minute...", Toast.LENGTH_SHORT).show()
override fun doInBackground(vararg urls: String): Bitmap? {
val imageURL = urls[0]
var image: Bitmap? = null
try {
val `in` = java.net.URL(imageURL).openStream()
image = BitmapFactory.decodeStream(`in`)
catch (e: Exception) {
Log.e("Error Message", e.message.toString())
e.printStackTrace()
return image
override fun onPostExecute(result: Bitmap?) {
imageView.setImageBitmap(result)
And this will be your image view:
<ImageView
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitCenter" />
Then whenever you want to display an HTTP image, just write the following lines:
val imageView: ImageView = findViewById(R.id.imageView)
FetchImageFromInternet(imageView)
.execute("https://www.nasa.gov/sites/default/files/styles/full_width_feature/public/thumbnails/image/stsci-01gfnn3pwjmy4rqxkz585bc4qh.png")
Run the app now and you will be able to view that HTTP image in your app. Check out our more tutorials on
