I have a uri of image from firebase but i don't know how to load it into bitmap, because i needed to cut the four corner edge of the image.

I tried it with resource id by providing drawable icon and it does worked fine, but not working from uri

Below is my code:

        uri imagefile = model.getImageUri();

        if (imagefile !=null){

        imageView.setVisibility(View.VISIBLE);


        Resources res = c.getResources();

        //How i'm loading the image
        Bitmap src = BitmapFactory.decodeResource(res, 
        Integer.parseInt(imagefile)); 


        RoundedBitmapDrawable dr =
        RoundedBitmapDrawableFactory.create(res, src);
        dr.setCornerRadius(Math.max(src.getWidth(), src.getHeight()) / 
        30.0f);
        imageView.setImageDrawable(dr);

    }

How to load image using uri? It will help me to solve other related issues as well. Thanks

I suggest you use AsyncTask to keep the process at the background so as to not lag the UI:

ImageLoadAsyncTask.java

public class ImageLoadAsyncTask extends AsyncTask<Void, Void, Bitmap> {

    private String url;
    private ImageView imageView;

    public ImageLoadAsyncTask(String url, ImageView imageView) {
        this.url = url;
        this.imageView = imageView;
    }

    @Override
    protected Bitmap doInBackground(Void... params) {
        try {
            URL urlConnection = new URL(url);
            HttpURLConnection connection = (HttpURLConnection) urlConnection.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap myBitmap = BitmapFactory.decodeStream(input);
            return myBitmap;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        super.onPostExecute(result);
        imageView.setImageBitmap(result);
    }
}

Then, use this codeto load your image from Firebase: 

ImageLoadAsyncTask imageLoadAsyncTask = new ImageLoadAsyncTask(url, imageView);
 imageLoadAsyncTask.execute();

Good Luck!
