Camera Intent Returns Null

Question

Intent를 사용하여 기본 카메라로 내 안드로이드 응용 프로그램에서 이미지 및 비디오를 캡처하려고합니다. 위의 코드를 사용하여

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); 

      startActivityForResult(intent, IMAGE_FROM_CAMERA); 

i는 이미지를 캡처하기 위해 노력하고 onActivityResult에 내가 의도로 열린 우리당을 지나가는 시도 data.getData()

에서 데이터에 널 얻고 있지만, 열린 우리당은 빈 가져옵니다.

카메라 인 텐트는 URI에 이미지를 쓸 수 없습니다. 이메일로 이미지 비디오를 보내려면 uri가 필요합니다.

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
File dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM); 
File output = new File(dir, "camerascript.png"); 
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(output)); 
startActivityForResult(cameraIntent, 1);
