How to convert bitmap to PNG and then to base64 in Android?
Try this to convert bitmap into png:
bitmap.compress(Bitmap.CompressFormat.PNG, quality, outStream);Check method's documentation.
You can directly convert bitmap to Base64. Use this for encoding and decoding from and to Base64.
public static String encodeToBase64(Bitmap image){ Bitmap immagex=image; ByteArrayOutputStream baos = new ByteArrayOutputStream(); immagex.compress(Bitmap.CompressFormat.JPEG, 100, baos); byte[] b = baos.toByteArray(); String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT); Log.e("LOOK", imageEncoded); return imageEncoded;}public static Bitmap decodeBase64(String input) { byte[] decodedByte = Base64.decode(input, 0); return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length); }
