我从社交网络分享了一张图片并用我的应用程序捕获它（按照此链接），但它捕获的是纯文本而不是图像，我尝试解析为 uri 和 url 但它不起作用

void handleSendText(Intent intent) {
    String sharedText2 = intent.getStringExtra(Intent.EXTRA_TEXT);
    //Bn1.setText("Descargar Texto plano");
    if (sharedText2 != null) { // check if is null or not
        File folder = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Imgs/");
        if(!folder.exists()){folder.mkdir();}// create folder
        int diagonal = sharedText2.indexOf(":");
        String sharedText = sharedText2.substring(diagonal + 1, sharedText2.length());
        sharedText = sharedText.replace(" ", "");
        if (!sharedText.startsWith("htt")) {// check if it's starts with http or not
            sharedText = "https" + sharedText.substring(0, sharedText.indexOf("?"));
        }
        c = 1;
        Bitmap bitmap = null;
        Uri imageUri = Uri.parse(sharedText); // parse to uri
        Time now = new Time(); // time
        now.setToNow();
        String nombre = "Imagen-" + now.weekDay + "-" + now.month + "-" + now.year + "-" + now.minute + "_" + now.second;// name of the image
        if (imageUri != null) {
            try {
                bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
            } catch (IOException e) {
                e.printStackTrace();
            }
            File file = null;
            file = new File(folder.getAbsoluteFile(), nombre + ".jpg");
            try {
                FileOutputStream out = new FileOutputStream(file);
                bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
                //bitmap.compress(Bitmap.CompressFormat.WEBP, 90, out);
                out.flush();
                out.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
            Tv1.setMovementMethod(new ScrollingMovementMethod());
            Tv1.setText("Es una imagen\n" + imageUri + "\n" + file + "\nnombre:\n" + nombre); // show the name of the variables
            if (bitmap == null) {
                Tv1.setText(sharedText2 + "\n\nsharedtext\n" + sharedText);
            } else {
                Tv1.setText("SI quedo\n" + sharedText);
            }
        }
    }
}

EXTRA_TEXT应该是纯文本。EXTRA_STREAM，另一方面，应该是 a content: Uri（尽管通常你会得到 a file: Uri）。据推测，您寻求的信息将在EXTRA_STREAM，而不是EXTRA_TEXT。
