Resize the bitmap

Question

Im my project I am capturing the image from Camera app and displaying image in listview by using following code . MySimpleCursorAdapter:

public class MySimpleCursorAdapter extends SimpleCursorAdapter {

    public MySimpleCursorAdapter(Context context, int layout, Cursor c,
        String[] from, int[] to) {
        super(context, layout, c, from, to);
    }

    @Override
    public void setViewImage(ImageView image_v, String id) {

        String path = id;
        Bitmap b = BitmapFactory.decodeFile(path);
        image_v.setImageBitmap(resizedBitmap);

    }

}

List.java

String[] from = new String[]{DbManager.babyName, DbManager.baby_image}; 
        int[] to = new int[] {/*R.id.list_id,*/ R.id.drname12,R.id.imageView1};//,R.id.list_date};{                 
        MySimpleCursorAdapter   Adapter = new MySimpleCursorAdapter(this, R.layout.rowlayout, c1, from, to);       
        list.setAdapter(Adapter);

Every things is working fine till this point But when I try to resize the bitmap by using this piece of code

 Bitmap resizedBitmap = Bitmap.createScaledBitmap(b, 200, 200, true);

its giving following error :

Error is here check this properly

 Bitmap b = BitmapFactory.decodeFile(path);

your variable path or b may be null.

check these variable not equal to null then use them.
