Gallery 어플에 있는 이미지를 Crop 하여 가져오는 방법으로 intent 간에 data 가 100kb 가 넘어갈 경우

에러가 발생하므로 아래와같이 파일로 저장후 읽어들여 가져옴.

 

private static final String TEMP_PHOTO_FILE = "temporary_holder.jpg"; Intent photoPickerIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); photoPickerIntent.setType("image/*"); photoPickerIntent.putExtra("crop", "true"); photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri()); photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString()); startActivityForResult(photoPickerIntent, REQ_CODE_PICK_IMAGE); private Uri getTempUri() {      return Uri.fromFile(getTempFile()); } private File getTempFile() {      if (isSDCARDMounted())      {           File f = new File(Environment.getExternalStorageDirectory(),TEMP_PHOTO_FILE);           try {                  f.createNewFile();           } catch (IOException e) { }           return f;      }      else      {          return null;      } } private boolean isSDCARDMounted() {      String status = Environment.getExternalStorageState();      if (status.equals(Environment.MEDIA_MOUNTED)) {          return true;      }        return false; } protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {       super.onActivityResult(requestCode, resultCode, imageReturnedIntent);       switch (requestCode)       {            case REQ_CODE_PICK_IMAGE:                 if (resultCode == RESULT_OK)                 {                        if (imageReturnedIntent!=null)                       {                           File tempFile = getTempFile();                           String filePath= Environment.getExternalStorageDirectory() +                                                                                          "/temporary_holder.jpg";                           System.out.println("path "+filePath);                            Bitmap selectedImage = BitmapFactory.decodeFile(filePath);                            _image = (ImageView) findViewById(R.id.image);                           _image.setImageBitmap(selectedImage );                       }                 }       } }
