    startActivity(anotherIntent);

Start New Acticity from Current Activity With Passing Required Data

    Intent anotherIntent = new Intent(this, anotherActivity.class);
    anotherIntent.putExtra("key", "value");
    startActivity(anotherIntent);
    finish();

putExtra() method is used to send extra data from one activity to another.
Extract Data In Other Activity

    data = getIntent().getStringExtra("key");

getIntent() method returns the intent that started this activity.
getStringExtra() retrieves extended data from the intent.

Now, it turns out that it’s not possible to pass Bitmap as extended data. It needs to be converted to byteArray.
Pass Bitamp as Extended Data

    ByteArrayOutputStream bStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, bStream);
    byte[] byteArray = bStream.toByteArray();
    Intent anotherIntent = new Intent(this, anotherActivity.class);
    anotherIntent.putExtra("image", byteArray);
    startActivity(anotherIntent);
    finish();

Retrieve Bitmap in Other Activity

    Bitmap bmp;
    byte[] byteArray = getIntent().getByteArrayExtra("image");
    bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
