How to get front and back camera's megapixel that is designed for android device?

Question

How to identify front and back camera\'s Megapixel of an android device by using Android code? I had tried CameraInfo but am not getting megapixel. For example, To identify

Answer 1

I got megapixel by combining three different answers of stack overflow friends.

                Camera camera=Camera.open(0);    // For Back Camera
            android.hardware.Camera.Parameters params = camera.getParameters();
            List sizes = params.getSupportedPictureSizes();
            Camera.Size  result = null;

            ArrayList<Integer> arrayListForWidth = new ArrayList<Integer>();
            ArrayList<Integer> arrayListForHeight = new ArrayList<Integer>();

            for (int i=0;i<sizes.size();i++){
                result = (Size) sizes.get(i);
                arrayListForWidth.add(result.width);
                arrayListForHeight.add(result.height);
                Log.debug("PictureSize", "Supported Size: " + result.width + "height : " + result.height);  
                System.out.println("BACK PictureSize Supported Size: " + result.width + "height : " + result.height);  
            } 
            if(arrayListForWidth.size() != 0 && arrayListForHeight.size() != 0){
                System.out.println("Back max W :"+Collections.max(arrayListForWidth));              // Gives Maximum Width
                System.out.println("Back max H :"+Collections.max(arrayListForHeight));                 // Gives Maximum Height
                            System.out.println("Back Megapixel :"+( ((Collections.max(arrayListForWidth)) * (Collections.max(arrayListForHeight))) / 1024000 ) );
            }
            camera.release();

            arrayListForWidth.clear();
            arrayListForHeight.clear();

            camera=Camera.open(1);        //  For Front Camera
            android.hardware.Camera.Parameters params1 = camera.getParameters();
            List sizes1 = params1.getSupportedPictureSizes();
            Camera.Size  result1 = null;
            for (int i=0;i<sizes1.size();i++){
                result1 = (Size) sizes1.get(i);
                arrayListForWidth.add(result1.width);
                arrayListForHeight.add(result1.height);
                Log.debug("PictureSize", "Supported Size: " + result1.width + "height : " + result1.height);  
                System.out.println("FRONT PictureSize Supported Size: " + result1.width + "height : " + result1.height);  
            } 
            if(arrayListForWidth.size() != 0 && arrayListForHeight.size() != 0){
                System.out.println("FRONT max W :"+Collections.max(arrayListForWidth));
                System.out.println("FRONT max H :"+Collections.max(arrayListForHeight));
                            System.out.println("FRONT Megapixel :"+( ((Collections.max(arrayListForWidth)) * (Collections.max(arrayListForHeight))) / 1024000 ) );
            }

            camera.release();

For obtaining megapixel, (Biggest Width x Height) / 1024000 = Megapixel
