난 네이티브 cpp 측면에서 이미지를로드하고 자바 클래스에서 내 안드로이드 애플 리케이션에서 해당 이미지를 표시하는 함수를 호출 기반으로 연구 찾고 있습니다.

  • 현재 나는 cpp 쪽에서 문자열 (url) 만 전달하여 이미지를 추가하고 있습니다.
  • 이미지 부분을로드하는 것은 Java 클래스 자체에서 수행됩니다.

    private class DownloadImageFromInternet extends AsyncTask {
    ImageView imageView;
    
    public DownloadImageFromInternet(ImageView imageView) {
        this.imageView = imageView;
        Toast.makeText(getApplicationContext(), "Please wait...", Toast.LENGTH_SHORT).show();
    }
    
    protected Bitmap doInBackground(String... urls) {
        String imageURL = urls[0];
        Bitmap bimage = null;
        try {
            InputStream in = new java.net.URL(imageURL).openStream();
            bimage = BitmapFactory.decodeStream(in);
    
        } catch (Exception e) {
            Log.e("Error Message", e.getMessage());
            e.printStackTrace();
        }
        return bimage;
    }
    
    protected void onPostExecute(Bitmap result) {
        imageView.setImageBitmap(result);
    }
    
    
    } 

이 안드로이드 측면에서 이미지를로드 내 샘플 코드입니다
