Android convert base64 encoded string into image view - android

I want to convert base64 encoded string into bitmap so i can put it in image view, but getting error like
D/skia(7490): --- decoder->decode returned false and bitmap returns null value
My code is:
byte[] imageAsBytes = Base64.decode(imageData);
image.setImageBitmap(BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length));


Firts you have to check that the string you want to decode is vaild and has the intended value to be decoded and to do so, you can do something like below:
filePath= Environment.getExternalStorageDirectory()
+ "/SaudiScore/temporary_holder.jpg";
Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
selectedImage.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();
String strBase64=Base64.encodeToString(byteArray, 0);
then you can decode the string that you just encoded and get the image back by doing something like the following:
byte[] decodedString = Base64.decode(strBase64, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
image.setImageBitmap(decodedByte);


byte[] decodedString = Base64.decode(mBase64string, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0,decodedString.length);
mImageView.setImageBitmap(decodedByte);


String base = "Base64 string values of some image";
byte[] imageAsBytes = Base64.decode(base.getBytes(), Base64.DEFAULT);
ImageView image = (ImageView) this.findViewById(R.id.imageView1);
image.setImageBitmap(BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length));
Try this code.


This method can help:
private void setExistImage(ImageView imageView, String base64String){
if (!base64String.isEmpty()) {
byte[] bytes = Base64.decode(base64String, Base64.DEFAULT);
imageView.setImageBitmap(BitmapFactory.decodeByteArray(bytes, 0, bytes.length));
}
}


Decode/Convert base64 string to image
imageBytes = Base64.decode(imageString, Base64.DEFAULT);
Bitmap decodedImage = BitmapFactory.decodeByteArray(imageBytes, 0,imageBytes.length);
image.setImageBitmap(decodedImage);


byte[] decodedString = Base64.decode(strBase64, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
image.setImageBitmap(decodedByte);
I was using the above solution .It always returned errors like decoded String is null,IllegalStateException ..
All I did was I just wrapped that in a try catch

facing problem while convert byte array to bitmap in android

my code
String passenger_sign = assignedJobJson.getJSONObject(position).getString("passenger_sign");
Log.e(TAG, "passenger_sign: "+passenger_sign );
byte[] Bytedata = passenger_sign.getBytes();
Log.e(TAG, "Bytedata: "+Bytedata );
ByteArrayInputStream arrayInputStream = new ByteArrayInputStream(Bytedata);
Bitmap bitmap = BitmapFactory.decodeStream(arrayInputStream);
//Bitmap bmp = BitmapFactory.decodeByteArray(Bytedata, 0, Bytedata.length);
Log.e(TAG, "bitmap: "+bitmap );
problem
i want to convert byte array to bitmap but it showing only null value while converting to bitmap.

Assuming your passenger_sign contains the image data converted in Base64, you can apply the following code:
byte[] decodedString = Base64.decode(passenger_sign, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
// Now, we set the decoded bytes to an image view to check if conversion is successfull
imageView.setImageBitmap(decodedByte);

Converting Image into Base64 String Android

This is my code. I am converting my Gallery image into base 64 string. this base 64 string is saving through this code in database but when i decode that string that gives me mime error. why this is happening?
if (resultCode == Activity.RESULT_OK) {
// Picasso.get().load(data.getData()).into(ivprofile);
filePath = data.getData().getPath();
Glide.with(this).load(data.getData()).into(ivprofile);
ivprofile.getDrawingCache();
Bitmap bitmap = ivprofile.getDrawingCache();
ByteArrayOutputStream stream=new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] image=stream.toByteArray();
img_str = Base64.encodeToString(image, Base64.DEFAULT);
}

follow the reference code in order to encode and decode image using base64 in android.
//encode image to base64 string
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.logo);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String imageString = Base64.encodeToString(imageBytes, Base64.DEFAULT);
//decode base64 string to image
imageBytes = Base64.decode(imageString, Base64.DEFAULT);
Bitmap decodedImage = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
image.setImageBitmap(decodedImage);

You need to enable drawing cache before you can get bitmap from imageview. Use below code for it.
imageView.setDrawingCacheEnabled(true);
imageView.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
imageView.layout(0, 0,
imageView.getMeasuredWidth(), imageView.getMeasuredHeight());
imageView.buildDrawingCache(true);
Bitmap bitmap = Bitmap.createBitmap(imageView.getDrawingCache());
imageView.setDrawingCacheEnabled(false);
or you can simply use this.
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();

You can do that in the following way:
Saving to db
byte[] data = text.getBytes("UTF-8");
String base64 = Base64.encodeToString(data, Base64.DEFAULT);
Receiving from db
byte[] data = Base64.decode(base64, Base64.DEFAULT);
String text = new String(data, "UTF-8");
For more information, check Base64

is there a way to load the dataUrl in imageview?

First you need to convert the Base64 encoded string to a Bitmap.
Code snippet below from linked question:
byte[] decodedString = Base64.decode("Your Base64 String", Base64.DEFAULT);
Bitmap bitMap = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
When that is done you have your bitmap in bitmap
Assuming your imageViewis defined as R.id.image_view
Then just do as you would with any other bitmap:
ImageView imageView;
imageView = (ImageView) findViewById(R.id.image_view);
imageView.setImageBitmap(bitmap);

Since I was getting the error:
java.lang.IllegalArgumentException: bad base-64
, I used the following workaround:
import java.io.ByteArrayInputStream
import java.io.InputStream
import android.util.Base64
...
val imageData: ByteArray = Base64.decode(dataUri.substring(dataUri.indexOf(",") + 1), Base64.DEFAULT)
val inputStream: InputStream = ByteArrayInputStream(imageData)
val bitmap: Bitmap = BitmapFactory.decodeStream(inputStream)
imageViewComponent.setImageBitmap(bitmap)
Perhaps it will help someone.

Just decode the Base64 image encoding using Base64.decode() method to receive a byte array, and then create the Bitmap using BitmapFactory.decodeByteArray() method.

If you take the Base64 part of the input, it can easily be converted to a Bitmap via this:
byte[] decodedString = Base64.decode("your base64 string", Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);

get base64 string in String variable decode
String encodedImage;// set base64 string value in this string
byte[] decodedString = Base64.decode(encodedImage, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);

Showing image in ImageView after Decoding without Compression

In my android application i am taking image from camera , then i want to encode it without compression.Then after encoding i want to decode and show in image view
Following is the code, with compression and it is working perfectly(image is showing in image view)
Bitmap thumbnail;
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.PNG, 1, bytes);
byte[] b = bytes.toByteArray();
String ImageString = Base64.encodeToString(b, Base64.DEFAULT);
byte[] bytarray = Base64.decode(ImageString, Base64.DEFAULT);
Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,bytarray.length);
imageView11.setImageBitmap(bmimage);
But when i use following code image donot showup in imageView. please please please help
int bytes = b.getWidth()*b.getHeight()*4;
ByteBuffer buffer = ByteBuffer.allocate(bytes);
thumbnail.copyPixelsToBuffer(buffer);
byte[] b = buffer.array();
String ImageString = Base64.encodeToString(b, Base64.DEFAULT);
byte[] bytarray = Base64.decode(ImageString, Base64.DEFAULT);
Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,bytarray.length);
imageView11.setImageBitmap(bmimage);

How to convert base64Binary string to image in Android?

i tried this code
byte decodedIcon[] = null;
byte[] bb = (resposeString).getBytes("utf-8");
decodedIcon = Base64.decodeBase64(bb);
Bitmap bitmap = BitmapFactory.decodeByteArray(decodedIcon, 0,decodedIcon.length);
I included commons-codec-1.3.jar
Still it returns null, any help will be greatly appreciated.

I use Following function for convert Base64 String to Image.
public Bitmap Base64ToImage(String base64String) {
byte[] imageAsBytes = Base64.decode(base64String.getBytes(),
Base64.DEFAULT);
Bitmap mybitmap = BitmapFactory.decodeByteArray(imageAsBytes, 0,
imageAsBytes.length);
return mybitmap;
}
