Answer 1

试试这个

private class myTask extends AsyncTask<Void, Void, Bitmap> {


    protected Bitmap doInBackground(Void... params) {
        Bitmap myBitmap=null;
        try {
            URL url = new URL(src);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            myBitmap = BitmapFactory.decodeStream(input);

        } catch (IOException e) {
            // Log exception
        }
        return myBitmap;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        //do stuff

    }
}

 Bitmap returned_bitmap = new myTask().execute().get()



Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "download this image");
String bitmapPath = Images.Media.insertImage(getContentResolver(), returned_bitmap,"title", null);
Uri bitmapUri = Uri.parse(bitmapPath);    
intent.putExtra(Intent.EXTRA_STREAM, bitmapUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via..."));

The documentation for EXTRA_STREAM说，Uri需要有一个content计划。 file通常也适用，至少在Android 6.0及更早版本上。很少有应用程序会期望http URL。
