How to convert a string image path to Base64 string in android?

Question

so im working with uploading string paths into imageViews, and it works fine, but my IOS app cannot use my string paths, so i need to switch over to base 64 strings. How do I convert my string path into a base 64 image and upload that into an imageview without it having out of memory error?

Below is what I currently have on myActivityResult().

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        addImageImageView.setVisibility(View.GONE);
        if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK && data != null) {
            //First we gotta make sure to add the images to
            ArrayList<Image> imagesFromGallery = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);//Image is a personal object I made.

            for (int i = 0; i < imagesFromGallery.size(); i++) {
                images.add(imagesFromGallery.get(i).path);
                LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
                lp.setMargins(20, 20, 0, 0);//5dp = 20 pixels
                lp.height = 720;//180dp = 720pixels
                lp.width = 1400;//330dp = 1320 pixels.
                ImageView newImageView = new ImageView(this);
                newImageView.setLayoutParams(lp);
                Glide.with(this).load(imagesFromGallery.get(i)).centerCrop().into(newImageView);
                imageLinearLayout.addView(newImageView, 0);
            }
    }

You can use the Base64 Android class:

String encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);

You'll have to convert your image into a byte array first. Here's an example:

Bitmap bm = BitmapFactory.decodeFile("/path/to/image.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object   
byte[] b = baos.toByteArray();

so the byteArrayImage is b.

String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);

so what would be byteArrayImage? – TheQ Oct 29 '16 at 05:51
