    At times, we make apps which use camera feature but that app can also be used on non camera devices for other features. There we have to apply a check on using the camera feature, that is as follows:

    PackageManager packageManager = activity.getPackageManager();
    
        //checking if device has camera
        if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
            //yes, perform the further camera code here.
            Toast.makeText(activity, "The device has camera.", Toast.LENGTH_SHORT).show();
        }else{
            //camera not found.
            Toast.makeText(activity, "The device has no camera.", Toast.LENGTH_SHORT).show();
        }
    

    PackageManager class used above can also be used to detect other features like wifi, bluetooth, flash, autofocus, gps, network etc.
