我正在尝试获取imageview的文件路径/uri，以保存到aws的s3数据库中。我尝试使用imageview的位图/drawable，但无法获取路径。是否有其他方法获取imageview的文件路径/uri？以下是我到目前为止所写的内容，但它不起作用：

private void uploadInputStream() {

        Uri path = Uri.parse("com.example.project/" + R.id.ivProfilePicture);
        String imgPath = path.toString();

        InputStream exampleInputStream = null;
        try {
            exampleInputStream = getContentResolver().openInputStream(path);

            Amplify.Storage.uploadInputStream(
                    "ExampleKey",
                    exampleInputStream,
                    result -> Log.i("MyAmplifyApp", "Successfully uploaded: " + result.getKey()),
                    storageFailure -> Log.e("MyAmplifyApp", "Upload failed", storageFailure)
            );
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }

以下是我使用上述代码得到的错误：

嘿，我就是这么做的，试试看

private void uploadInputStream() {

    Uri path = Uri.parse("com.example.project/" + R.id.ivProfilePicture);

    Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);

    InputStream exampleInputStream = null;
    File file = null;

    try {
      exampleInputStream =
      getContentResolver().openInputStream(Uri.parse(bitmap));

      file = new File(String.valueOf(inputStream)); //upload the file

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
}

让我知道进展如何
