Bitmap image with rounded corners with stroke

Question

I have a image with sharp edges.

the tile_mode.xml

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/background"
    android:tileMode="repeat">
</bitmap>

the back.xml

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">  
       <item android:drawable="@drawable/tile_mode" />
    <item>
        <shape>
            <solid/>
            <stroke android:width="1dip" android:color="#225786" />
            <corners android:radius="10dip"/>
            <padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
        </shape>
    </item> 

layout.xml

<LinearLayout
                android:id="@+id/frame1"
                android:background="@drawable/back"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content">
            </LinearLayout>

I am setting the image as a background to this layout and drawing a border to it but the problem is the image is square with sharp edges and the border which I am drawing in the xml is rounded corners. So how to make the image also with rounded corners?

Pass original bitmap to the following function and you will get a rounded bitmap as result :) . Hope this helps someone.

 public Bitmap getRoundedBitmap(Bitmap bitmap) {
        Bitmap resultBitmap;
        int originalWidth = bitmap.getWidth();
        int originalHeight = bitmap.getHeight();
        float r;

        if (originalWidth > originalHeight) {
            resultBitmap = Bitmap.createBitmap(originalHeight, originalHeight,
                    Bitmap.Config.ARGB_8888);
            r = originalHeight / 2;
        } else {
            resultBitmap = Bitmap.createBitmap(originalWidth, originalWidth,
                    Bitmap.Config.ARGB_8888);
            r = originalWidth / 2;
        }

        Canvas canvas = new Canvas(resultBitmap);

        final Paint paint = new Paint();
        final Rect rect = new Rect(ConstsCore.ZERO_INT_VALUE,
                ConstsCore.ZERO_INT_VALUE, originalWidth, originalHeight);

        paint.setAntiAlias(true);
        canvas.drawARGB(ConstsCore.ZERO_INT_VALUE, ConstsCore.ZERO_INT_VALUE,
                ConstsCore.ZERO_INT_VALUE, ConstsCore.ZERO_INT_VALUE);
        canvas.drawCircle(r, r, r, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);

        return resultBitmap;
    }
