Everybody must have seen on Google Play that whenever we click install button on the website the particular app is downloaded and installed on the android device owned by user. How could I possibly do that on my android app and website i.e If the user logon to my website with his gmail Id and buys a product (which are some data files) and those files are downloaded to the sdcard of the android device. Have any one worked on similar technique and how it could be possible. Please help?
