android分享图片从url使用数组？

<uses-permission android:name="android.permission.INTERNET" />

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    protected Bitmap doInBackground(String... urls) {
        String imageUrl = urls[0];
        Bitmap bitmap = null;
        try {
            URL url = new URL(imageUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            bitmap = BitmapFactory.decodeStream(input);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bitmap;
    }
}

DownloadImageTask task = new DownloadImageTask();
task.execute(imageUrl);

Bitmap bitmap = task.get(); // 获取异步任务的结果

if (bitmap != null) {
    File imageFile = new File(getExternalFilesDir(null), "image.jpg");
    FileOutputStream outputStream = new FileOutputStream(imageFile);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
    outputStream.close();
}

File imageFile = new File(getExternalFilesDir(null), "image.jpg");
Uri imageUri = FileProvider.getUriForFile(this, "com.example.fileprovider", imageFile);

Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(shareIntent, "Share Image"));
