Convert image to base64 String and vice versa
Image to base64 String To convert image to base64 String use the code given below. 1. Define a new ByteArrayOutputStream. java.io.ByteArrayOutputStream baos = new java.io.ByteArrayOutputStream(); 2. Convert image in ImageView to Bitmap. Bitmap bm = ((android.graphics.drawable.BitmapDrawable) imageview1.getDrawable()).getBitmap(); Or convert image in drawable folder to Bitmap. Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image); 3. Convert bitmap image to byte array and encode it to String. bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); byte[] imageBytes = baos.toByteArray(); String imageString = android.util.Base64.encodeToString(imageBytes, android.util.Base64.DEFAULT); Base64 String to image 1. Decode String to Byte array byte[] imageBytes = android.util.Base64.decode(imageString, android.util.Base64.DEFAULT); 2. Convert Byte array to Bitmap Bitmap decodedImage = BitmapFactory.decodeByteArray(imageBytes, 0, ima...
