Base64 Encoding takes too long time in Android

Question

I'm capturing an Image with the Camera. I save the File in the public photo directory and save the Uri to that file.

I want to save the Image in a Base64 String and put it on a HashMap to put it then in a XML file later.

protected Void doInBackground(Void...voids) {
        options.inJustDecodeBounds = false;
        //Bitmap bmp = BitmapFactory.decodeFile(imageFilePath,options);
        InputStream in = null;
        try {
            in = getContentResolver().openInputStream(Uri.parse(mCurrentPhotoPath));
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        options.inSampleSize = 2;
        Bitmap image = BitmapFactory.decodeStream(in,null,options);
        int imgHeight = image.getHeight();
        int imgWidth = image.getWidth();
        while(imgHeight>2000){
            imgHeight = imgHeight / 2;
        }
        while(imgWidth>2000){
            imgWidth = imgWidth / 2;
        }

        Bitmap test = Bitmap.createScaledBitmap(image,imgWidth,imgHeight,false);

        String stest = base64EncodeDecode.encodeToBase64(test);


        items.put("image",base64EncodeDecode.encodeToBase64(test);
        return null;
}

The Base64 takes too long to encode it. encodeToBase64 Method

public String encodeToBase64(Bitmap image) {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    image.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] b = baos.toByteArray();

    return Base64.encodeToString(b, Base64.DEFAULT);
}

Can you tell me if I do something wrong while encoding?

I hope my problem is clear.

Kind Regards!

If you are getting !!! FAILED BINDER TRANSACTION !!! error is probably because you are passing to much data to the other Activity, there is a limit of how much you can send. Try compressing your image to 50% or 30% image.compress(Bitmap.CompressFormat.JPEG, 50, baos);
