    Uri fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

    try {
        intent.putExtra("return-data", true);
        startActivityForResult(
                Intent.createChooser(intent, "Select Picture"), code);
    } catch (Exception e) {

    }

}

I am getting NullPointerException

  java.lang.NullPointerException: file

There is no inbuilt method getoutputmediafileuri() in android. It is a custom method someone write for getting file URI to store captured images in particular directory. You have to defined and put logic for it. Instead of that use this code,

   Intent imageIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
   File imagesFolder = new File(Environment.getExternalStorageDirectory(),"MyImages");
   imagesFolder.mkdirs(); // <----
   File image = new File(imagesFolder, "image_001.jpg");
   Uri uriSavedImage = Uri.fromFile(image);
   imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
   startActivityForResult(imageIntent,0);
