Offline Capability #26
Description
Im thinking of adding offline capability to the app. I ride the subway where there is no cellular or wifi which renders the app useless. It is a big feature and here is a break down of things that will be needed:
- Availability checker: Its sole responsibility is to signal when there is no wifi/cellular connectivity.
- Add caching functionality to the StringNetworkService class that checks and pulls from local directory if it exists instead of making a network call
- Give the ability to users to download all or individual algorithm/puzzle/categories
- show error messages when there is no connectivity or attempt to access a non-downloaded resource
