안드로이드 이미지 사이즈 조절

Question

Uri를 가지고 비트맵으로 변경후 사이즈 조절 후 

다시 Uri 받아오고 싶은 어떻게 해야 할지 잘모르겠네요. 

해볼려고 했는데 ... 계속 에러가

	public Uri iamgeSizeChange(Uri selPhtoUri, String imageName){
		
		String path = null;
		
		try {
			Bitmap bm = Images.Media.getBitmap(getContentResolver(), selPhtoUri);
			bm = Bitmap.createScaledBitmap(bm, 90, 90, true);

			ByteArrayOutputStream bytes = new ByteArrayOutputStream();
			bm.compress(CompressFormat.JPEG, 100, bytes);
			path = Images.Media.insertImage(getContentResolver(), bm, imageName, null);
			
			
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return Uri.parse(path);

	}

 

최종 목적은 파일서버에 저장 하는 것입니다.
