Write an Android application

one crucial point about this app is that i would like to be able to use it as a standard flashcard app, such as Anki, but i also want the flash cards to show up on the lock screen of the phone. swipe left/right/down if the card is easy/hard/average to unlock the phone (this will be how the spaced repetition system works - more on that later). apart from the standard flashcard app features that you would expect on a flashcard app i would like the app to be able to do the following. create multiple flash cards and multiple choice cards at once. I was thinking of a 4 column creation page showing a text box for what is to be on side a, side b, optional extras such as changing colour/style of text, add sounds and pictures that can be loaded from the phone or online source and the last column will be a confirmation button so that the creator can click apply to individual cards or use a "create all" button at the bottom of the list. when the screen unlocks i'd like a non intrusive flash of red/green for wrong/right answer with the entire flash card to appear as a notification from the side of the screen. similar style to facebook chat but showing side a and b of the card and any hint/background to be shown with the cards. customizable design for flash cards on the lock screen (size, position etc) - done through app. add an advert once every 50 flash cards on the lock screen. have an option to export cards onto a printable pdf file. set alarms through the app and you have to answer a flashcard to stop the alarm. an auto translate option on the card creation. cards to cycle through using the spaced repetition system (if you need more information on this i can find some for you). import flashcards from a word document. history page showing the previous 10-20 cards shown in app and lock screen. hint option on lock screen and app. pre-loaded (royalty free) pictures to go with set vocabulary (picture of common words like dog, roads, house etc) the option to add non-intrusive adds along the bottom of the app. create admin panels and APIS (version 2 is already under discussion - possibility of follow up work)
