Write an Android application

Hello, We are seeking the quotation for building additional special functionality in our Android App or to pre-install it on encrypted SD Card. We already have an Android App named Qeasily. This learning app downloads the content/data i.e. images, videos, webpages, texts/audio etc.. when connected to internet and stores it natively so it can be access in offline mode. All the downloaded content has expiration date and can be viewed only through the App if access/subscription is active. After expiry, user cannot login to the app home-screen. Since the data volume is huge in GBs, we would like to take it to next level by developing following features or separate product- 1. Transfer App along with data through wired/USB connection- Here we would like to transfer the app from source device (phone or tablet) to target device (tablet/phone). i.e. Install the app on user's android device (tablet or phone) by connecting it to Source device (phone/tablet) that has the app along with content. Then the app in target device will be activated with one-time installation key. 2. Pre-install everything on SD Card- Install the App along with data on SD/memory card so we can directly give the SD card with encryption to the user. This SD card will be encrypted can be installed only after one-time usage/installation key. This way user will not have to consume the wireless bandwidth and everything is available to them instantly rather than sequential download of content through web. We also welcome your ideas on achieving this by other methods. Response Requirements- 1. We request you to download the app and study it so you get an idea of it's structure and how it works in offline mode. 2. Include in detail- How you will achieve this? Technical strategy/approach than just project phases or just listing your company details or profile 3.
