Failed binder transaction when returning camera image

android88 · by **android88** » Sun Feb 14, 2010 5:14 pm

Hi, I get the Failed binder transaction error when returning the image taken with the camera from the camera intent back to the parent intent (as a byte[]). I don't understand why, its not like its a big bitmap or anything. It only happens when i take pictures with lots of light, because then the byte[] is bigger. Does anyone see a mistake in my code?

Here is my code:

Hi,
I was facing the same problem. The only solution I consider is to compress the image:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

        BitmapFactory.Options options = new BitmapFactory.Options();
 
                        options.inSampleSize = 2;
 
                        Bitmap temp_image = BitmapFactory.decodeByteArray(data, 0, data.length, options);
 
                        ByteArrayOutputStream out =  new ByteArrayOutputStream();
 
                        temp_image.compress(CompressFormat.JPEG, 60, out);
 
                        byte[] temp_data = out.toByteArray();
 
                   Intent intent = new Intent();
 
                   intent.putExtra("image_data", temp_data);
 
                   setResult(SUCCESS_RETURN_CODE_IMAGE,  intent);
 
               PictureCapturer.this.finish();

Hope it helps.

Had the same problem. Converted picture, now it works perfectly. But i registered some errors in the post before. The method should look like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 Camera.PictureCallback mPictureCallback = new Camera.PictureCallback(){
      public void onPictureTaken(byte[] imageData, Camera c) {
 
          if (imageData != null) {
 
                 //StoreByteImage(mContext, imageData, 50, "ImageName");
              
              BitmapFactory.Options options = new BitmapFactory.Options();
              options.inSampleSize = 2;
 
              Bitmap temp_image = BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options);
 
              ByteArrayOutputStream out =  new ByteArrayOutputStream();
              temp_image.compress(CompressFormat.JPEG, 60, out);
              byte[] temp_data = out.toByteArray();
 
              Intent intent = new Intent();
              intent.putExtra("image_data", temp_data);
              setResult(FOTO_MODE,  intent);
 
              CameraActivity.this.finish();
 
          }
      }
  };
