You can achieve this by web service. Just create one web service where you have to integrate bitcoin properly using bitcoin library (https://github.com/bitpay/php-bitpay-client) and tutorial https://github.com/bitpay/php-bitpay-client/tree/master/examples/tutorial. Web service should be one PHP file and you have load to android web view control. And manage the success or failure messages.
