Question

I am trying to set up an alert dialog, using the below code, but the app keeps crashing on this point. Any obvious mistakes?

AlertDialog alertDialog = new AlertDialog.Builder( 
    Crossword1.this).create(); 
    alertDialog.setTitle("Well done, the crossword is complete!");
    alertDialog.setMessage("well done cuz");
    alertDialog.setIcon(R.drawable.tick);
    alertDialog.setButton("OK", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int which) { 

        } 
    });
alertDialog.show();

Logcat below, mentions memory although I don’t see why the alertdialog box should be causing a memory error (the app runs fine if the alertdialog is commented out)

Thanks @Andro Selva for the answer
The memory problem is being caused by the icon. If I comment out the icon line of code then the dialog runs fine.

If I resize the icon like so, then the whole thing runs fine

    //---scales the alertdialog items to the right size---
    Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(), R.drawable.tick); 
    int width = bitmapOrg.getWidth(); 
    int height = bitmapOrg.getHeight(); 
    int newWidth = 200; 
    int newHeight = 200;

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

    // create matrix for the manipulation
    Matrix matrix = new Matrix();  

    // resize the bit map
    matrix.postScale(scaleWidth, scaleHeight);

    // rotate the Bitmap
    matrix.postRotate(0);  

    // 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);
