Find Mobile's Camera pixels programmatically

I searched for past two days and i was not successful yet .

I my case , i want to check the camera pixel resolution/Megapixels . If the camera's Mp is more than 4 then i need to re-size and upload .

Here is my code :

//to check the resolution

Camera mcamera ;

mcamera = Camera.open(Camera.CameraInfo.CAMERA_FACING_BACK);

Camera.Parameters param = mcamera.getParameters();
Camera.Size size = param.getPictureSize();

cam_height = size.height ;
cam_width = size.width ;

mcamera.release();

// my functionality

BitmapFactory.Options resample = new BitmapFactory.Options();
if(cam_height > pict_height || cam_width > pict_width )
    resample.inSampleSize = 2;  // whatever number seems appropriate 2 means 1/2 of the original
else
    resample.inSampleSize = 1;

capturedimg = BitmapFactory.decodeFile(fileUri.getPath() , resample);
resized_uri = bitmaptouri(capturedimg);

but this returns only the picture resolution which is the same as the Screen resolution of the mobile but i want the Mobile camera's resolution .

Any related answers are welcomed , Thanks in advance .

Try the code from here. It returns resolution in mp for back camera. You should use getSupportedPictureSize instead of getPictureSize

First check the supported picture sizes available for the Camera using Camera.Parameters. There is a function called getSupportedPictureSizes() in Camera Parameters.

For e.g: 

List<Camera.Size> mList    =    mParams.getSupportedPictureSizes();
Camera.Size mSize          =    mList.get(mList.size() - 1);

From the mList you get all the supported Picture Sizes. The final one in the list will be the largest possible resolution.

First find height and width like below:

android.hardware.Camera.Parameters parameters = camera.getParameters();
android.hardware.Camera.Size size = parameters.getPictureSize();


int height = size.height;
int width = size.width;

then get mega pixel using below equation:

int mg = height * width / 1024000;

where mg is your mega pixels.

How about getSupportedPictureSizes()?
