How to crop the parsed image in android?

I assume you've already "got" the images down from the website and want to resize rather than crop? I.e. create thumbnails.

If so, you can use the following:

    // load the origial BitMap (500 x 500 px)
    Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(), 
           R.drawable.android);

    int width = bitmapOrg.width();
    int height = bitmapOrg.height();
    int newWidth = 200;
    int newHeight = 200;

    // calculate the scale - in this case = 0.4f
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;

    // createa matrix for the manipulation
    Matrix matrix = new Matrix();
    // resize the bit map
    matrix.postScale(scaleWidth, scaleHeight);

    // recreate the new Bitmap
    Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, 
                      width, height, matrix, true); 

    // make a Drawable from Bitmap to allow to set the BitMap 
    // to the ImageView, ImageButton or what ever
    BitmapDrawable bmd = new BitmapDrawable(resizedBitmap);

    ImageView imageView = new ImageView(this);

    // set the Drawable on the ImageView
    imageView.setImageDrawable(bmd);

    // center the Image
    imageView.setScaleType(ScaleType.CENTER);

Best link github -> AndroidImageCrop

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    photoPicker();
}

private void photoPicker() {
    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, 1);
}

private void crop(Uri photoUri) {
    Intent intent = new Intent("com.android.camera.action.CROP");
    intent.setData(photoUri);
    intent.putExtra("outputX", 200);
    intent.putExtra("outputY", 200);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    intent.putExtra("scale", true);
    intent.putExtra("return-data", true);
    startActivityForResult(intent, RESULT_CROP);
}

protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    if (resultCode == RESULT_OK) {
        Uri photoUri = intent.getData();
        if (photoUri != null) {
            Log.i("TAG", "Start Crop!!");
            crop(photoUri);
        }
    } else if (resultCode == RESULT_CROP) {
        Toast.makeText(this, "Image crop", Toast.LENGTH_SHORT).show();
    }
}

The Android Contact manager EditContactActivity uses Intent("com.android.camera.action.CROP")

This is a sample code:

Intent intent = new Intent("com.android.camera.action.CROP");
// this will open all images in the Galery
intent.setDataAndType(photoUri, "image/*");
intent.putExtra("crop", "true");
// this defines the aspect ration
intent.putExtra("aspectX", aspectY);
intent.putExtra("aspectY", aspectX);
// this defines the output bitmap size
intent.putExtra("outputX", sizeX);
intent.putExtra("outputY", xizeY);
// true to return a Bitmap, false to directly save the cropped iamge
intent.putExtra("return-data", false);
//save output image in uri
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);

Then, startActivityWithResult() to known wether the user pressed OK or Cancel. In the first case, the croped image will be saved in uri.
