How to get a Uri object from Bitmap

Question

On a certain tap event, I ask the user to add an image. So I provide two options:

1. To add from gallery.
2. To click a new image from camera.

Answer 1

Try to use the below Code. May be helpful to you:

new AsyncTask() {
            protected void onPreExecute() {
            };

            @Override
            protected Void doInBackground(Void... arg0) {
                imageAdapter.images.clear();
                initializeVideoAndImage();
                return null;
            }

            protected void onProgressUpdate(Integer... integers) {
                imageAdapter.notifyDataSetChanged();
            }

            public void initializeVideoAndImage() {
                final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Thumbnails._ID };
                String orderBy = MediaStore.Images.Media._ID;
                Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null, null, orderBy);

                final String[] videocolumns = { MediaStore.Video.Thumbnails._ID, MediaStore.Video.Media.DATA };
                orderBy = MediaStore.Video.Media._ID;
                Cursor videoCursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, videocolumns, null, null, orderBy);
                int i = 0;
                int image_column_index = 0;

                if (imageCursor != null) {
                    image_column_index = imageCursor.getColumnIndex(MediaStore.Images.Media._ID);
                    int count = imageCursor.getCount();
                    for (i = 0; i < count; i++) {
                        imageCursor.moveToPosition(i);
                        int id = imageCursor.getInt(image_column_index);
