인텐트로 비트맵 배열 넘기는방법

Question

안녕하세요 안드로이드펍 가족님들..

인텐트로  비트맵 배열을 넘길려고 하는데요.

 

구글링해서 해봤는데도 잘안되되는데요

http://stackoverflow.com/questions/15102057/how-to-pass-bitmap-array-between-2-activies

보내는부분분

Intent intent =new Intent(this,  aaaa.class);

 

intent.putExtra("bitmaps", mBitmap);

startActivity(intent);

 

//받는부분

Intent i = getIntent();

Bitmap [] bitmaps = (Bitmap[]) i.getParcelableArrayExtra("bitmaps");

 

아래와같은 에러가 나타납니다.

Answer 1

일단 아래 소스와 같이 코딩을 해 주시면 될듯 하긴 합니다만...

만약에 비트맵이미지가 클 경우에는 전달이 안되는 경우가 많습니다.

조그만 비트맵만 전달하실게 아니시라면 두 액티비티간에 사용할수 있는 공동저장소를 만드셔서

전달하시는게 좋을것 같습니다.

그럼 수고 하세요.

 

//Convert to byte array
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

Intent in1 = new Intent(this, Activity2.class);
in1.putExtra("image",byteArray);

Then in Activity 2:

byte[] byteArray = getIntent().getByteArrayExtra("image");
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

ㅜㅜ 다행이 그게되는거 같은데

인텐트로 넘길수 있는용량이 초과되었다고 합니다 ㅜㅜ

다른방법이 없나요
