Sending BitMap Between Activities:

Sending BitMap Between Activities:

In Activity 1 :
do like this---------------->
Which image you want to send to next activity
bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap(); // here imageView is an XML related image view.
       
Intent intent = new Intent(mContext, NextActivity.class);
        ByteArrayOutputStream bs = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, bs);
        intent.putExtra("byteArray", bs.toByteArray());
        startActivity(intent);


In Activity 2 :
try{
        if(getIntent().hasExtra("byteArray")) {
        bitmap = BitmapFactory.decodeByteArray(getIntent().getByteArrayExtra("byteArray"),0,getIntent().getByteArrayExtra("byteArray").length);      
                imageView.setImageBitmap(bitmap); // here imageView Activity 2 related imageView
            }
        }catch (Exception e) {
e.printStackTrace();
}

Android - Function to convert ImageURL to Bitmap object

IMAGE URL TO BITMAP

Use this function “convertURLtoBitmap”

public Bitmap convertURLtoBitmap(String src) {

                try {

                                URL url = new URL(src);
                                                
                                HttpURLConnection connection = (HttpURLConnection) url
                                                .openConnection();

                                connection.setDoInput(true);
                                connection.connect();

                                InputStream input = connection.getInputStream();
                                Bitmap myBitmap = BitmapFactory.decodeStream(input);

                                return myBitmap;

                }

                catch (IOException e) {

                                e.printStackTrace();
                                return null;

                }
}

Crop an Image in ANDROID.

Cropping an image in ANDROID programmatically has always been a problem for ANDROID developers.
So Here I am putting a sample code to demonstrate this.
For cropping an image in ANDROID we need a source bitmap which is our image itself, the other one is the target bitmap which we have to
set the size as we want and a matrix.

Below code is a fully working code, just copy and paste this code to your new project.
The XML for the code is also provided below.

Make sure that you have an image named “image.png” in your resources.
Assuming the image to be of size 300×300 pixels.
