There is no official API to download APKs programmatically. But to address your exception, it seems like you're using Apache HTTP Client and running your app on a device with Android Marshmallow (6.0) or above.

Apache HTTP Client has been removed as of Marshmallow. HttpURLConnection can be used instead.
