Hi guys I have a problem when I go to encode the image to a bitmap and then do a comparison with the decode an encoded image with tools via the Internet but does not give me the same decoding and can not figure out why.
String path = "/sdcard/bluetooth/bluetooth.png";
Bitmap bitmap = BitmapFactory.decodeFile(path);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, bao);
byte [] ba = bao.toByteArray();
String ba1=Base64.encodeToString(ba,Base64.DEFAULT);
I used the below for encoding and decoding and it works fine for me
Encode
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;
}
Try the below for decoding and set the resulting bitmap to imageview and check with the original.
Decode.
public static Bitmap decodeBase64(String input)
{
byte[] decodedByte = Base64.decode(input, 0);
return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}

This is my code and I tried lot of code varieties already...
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes,Base64.DEFAULT);
return encodedImage;
}
You can try following code to encode and decode image:
//Compress img and save
private String encodeBitmapAndSave(Bitmap bitmap1) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap1.compress(Bitmap.CompressFormat.PNG, 100, baos);
return Base64.encodeToString(baos.toByteArray(), Base64.DEFAULT);
}
//Decompress img
private Bitmap decodeFromFirebaseBase64(String image) throws IOException {
byte[] decodedByteArray = Base64.decode(image, Base64.DEFAULT);
return BitmapFactory.decodeByteArray(decodedByteArray, 0, decodedByteArray.length);
}
It's my MySql DB
Its encoding:-
public String convertBitmapToString(Bitmap bmp) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); //compress to which format you want.
byte[] byte_arr = stream.toByteArray();
String imageStr = Base64.encodeToString(byte_arr, 1);
return imageStr;
}
This is decoding:-
String img=o.toString();
byte[] imageAsBytes = Base64.decode(img.getBytes(), Base64.DEFAULT);
imageView.setImageBitmap(BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length));
Thank you.
It could be done by
private String getBase64String() {
// give your image file url in mCurrentPhotoPath
Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
// In case you want to compress your image, here it's at 40%
bitmap.compress(Bitmap.CompressFormat.JPEG, 40, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();
return Base64.encodeToString(byteArray, Base64.DEFAULT);
}
And for Decode
private void decodeBase64AndSetImage(String completeImageData, ImageView imageView) {
// Incase you're storing into aws or other places where we have extension stored in the starting.
String imageDataBytes = completeImageData.substring(completeImageData.indexOf(",")+1);
InputStream stream = new ByteArrayInputStream(Base64.decode(imageDataBytes.getBytes(), Base64.DEFAULT));
Bitmap bitmap = BitmapFactory.decodeStream(stream);
imageView.setImageBitmap(bitmap);
}
I am able to get an encoded String using the following code :
public static String encodeToBase64(Bitmap image, Bitmap.CompressFormat compressFormat, int quality) {
ByteArrayOutputStream byteArrayOS = new ByteArrayOutputStream();
image.compress(compressFormat, quality, byteArrayOS);
return Base64.encodeToString(byteArrayOS.toByteArray(), Base64.NO_WRAP);
}
BitmapDrawable drawable = (BitmapDrawable) imgPreview.getDrawable();
Bitmap bitmap = drawable.getBitmap();
encodedImage = encodeToBase64(bitmap, Bitmap.CompressFormat.JPEG, 100);
I get the following as String

But when i try to decode it using http://freeonlinetools24.com/base64-image nothing shows.
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.image);
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteStream);
byte[] byteArray = byteStream.toByteArray();
String baseString = Base64.encodeToString(byteArray,Base64.DEFAULT);
This worked for me.
I have found out the problem. The problem was with the logcat from where i was copying the encoded string. Logcat didn't display the entire String so the broken string didn't decode the image for me.
So when i passed the encoded string directly to the decode function the image was visible.
I checked an image with given link http://freeonlinetools24.com/base64-image and it works fine. I think the reason for getting wrong output is your string. Encoded string always ends with == . Check your encoded string.
Example Code
Encode Image
BitmapDrawable drawable = (BitmapDrawable) imgPreview.getDrawable();
Bitmap bitmap = drawable.getBitmap();
encodedImage = encodeToBase64(bitmap, Bitmap.CompressFormat.JPEG, 100);
public static String encodeToBase64(Bitmap image, Bitmap.CompressFormat compressFormat, int quality)
{
ByteArrayOutputStream byteArrayOS = new ByteArrayOutputStream();
image.compress(compressFormat, quality, byteArrayOS);
return Base64.encodeToString(byteArrayOS.toByteArray(), Base64.DEFAULT);
}
Decode Image
Bitmap bitmap = decodeBase64(encodedImage );
img.setImageBitmap(bitmap);
public static Bitmap decodeBase64(String input)
{
byte[] decodedBytes = Base64.decode(input,0);
return BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);
}
EDITED

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 though. 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();
Encode/Convert image to base64 string
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.yourimage);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String imageString = Base64.encodeToString(imageBytes, Base64.DEFAULT);
I am developing an android application which uploads Base64 String of image into web server. Therefore, I have used the following code to convert a Bitmap into Base64 String.
public String getEncoded64ImageStringFromBitmap(Bitmap bitmap) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteFormat = stream.toByteArray();
String imgString = Base64.encodeToString(byteFormat, Base64.NO_WRAP);
return imgString;
}
For example, I need to convert this image.
After the conversion, I'm not getting the Base64 String as I expected.

The real Base64 String it should be this (I use this website to convert)

What is the problem in my conversion ?
Thank you !
public static String encodeTobase64(Bitmap image) {
Bitmap immagex = image;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
immagex.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT);
return imageEncoded;
}
public static Bitmap decodeBase64(String input) {
byte[] decodedByte = Base64.decode(input, 0);
return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}
use the following snippet to convert bitmap to byte array:
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream .toByteArray();
then to encode base64 from byte array use the following statement:
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
public String getBase64ImageString(Bitmap photo) {
String imgString;
if(photo != null) {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
byte[] profileImage = outputStream.toByteArray();
imgString = Base64.encodeToString(profileImage,
Base64.NO_WRAP);
}else{
imgString = "";
}
return imgString;
}
Pass your Bitmap in the parameters you will get your image string.
Code stuff for convert from Bitmap to String Base64
Bitmap thumbnail = extras.getParcelable("data");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, baos);
thumbnail.recycle();
byte[] b = baos.toByteArray();
String attachment = Base64.encodeToString(b, Base64.DEFAULT);
Code stuff for convert from String Base64 to Bitmap
byte[] encodeByte = Base64.decode(strBase64, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
imageView.setImageBitmap(bitmap);
but i get bitmap = null;
I also refer Base64 to Bitmap to display in ImageView
Thanks in advance.
// convert Bitmap to String
public static String BitMapToString(Bitmap bitmap) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] arr = baos.toByteArray();
imageData = Base64.encodeToString(arr, Base64.DEFAULT);
return imageData;
}
// Convert String to Bitmap
public static Bitmap StringToBitMap(String image) {
try {
byte[] encodeByte = Base64.decode(image, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(encodeByte, 0,
encodeByte.length);
return bitmap;
} catch (Exception e) {
e.getMessage();
return null;
}
}
You are calling thumbnail.recycle(); after loading bitmap,, either remove it or call before loading bitmap
