Write an Android application

ATTENTION: WRITTEN AND SPOKEN ENGLISH ABILITY MUST BE VERY GOOD. Hi there, We want to upload an ANDROID app for Facebook messenger. But our developer is having problems. And we would like you to describe in a clearly written document the procedure to upload/create an APP/PLUG-IN for FACEBOOK MESSENGER, while answering our questions below in the document. Here are the links that you can gather information for the document from: LINK #1: Here are some of the apps that are already on Facebook for your reference: [login to view URL] LINK #2: Here is a link that describes how to implement an Android Application onto Facebook for your reference: [login to view URL] After you read thoroughly LINK #2, we would like you to describe to us in a document essentially what kind of APP it is we need to create. And answer the following questions in the document: 1. What kind of code would we need to use to build an ANDROID APP for Facebook MESSENGER? For example: HTML, PHP, XML? 2. Would it be possible by the code that’s described in FACEBOOK MESSENGER, to create an EMOJI that is a HYPERLINK? We need our EMOTICONS to be hyperlinks in FACEBOOK MESSENGER, as they are in our APP. 3. Do we need a pre-written, pre-made APP for FACEBOOK MESSENGER? Or do we have to write CODE/an APP specifically for FACEBOOK MESSENGER? 4. (same question as above, but more clear) Does FACEBOOK MESSENGER want us to start from scratch and create a new APP just for their platform, or can we use existing CODE / an existing APP that we’ve already created. 5. We want our APP to function primarily as a PLUG-IN on FACEBOOK MESSENGER, what kind of code needs to be written in order for our EMOTICON APP to function as a PLUG-IN. Again, to reiterate, our APP is an EMOTICON PLUG-IN, where the EMOTICONS are clickable hyperlinks. 6. Is it possible to make a PLUG-IN for FACEBOOK MESSENGER that allows our EMOTICONS to be hyperlinks? 7. How long would it take in hours to create an emoticon software for FACEBOOK? 8. How much would you quote to build this type of app for FACEBOOK MESSENGER? 9. When we contract this APP to our Developer, will there be FACEBOOK specific CODE? What we’re trying to say is that, we already have an APP for ANDROID, ready to install. But our developer, doesn’t know how to upload it (English is his second language). That being said, we’re concerned we may need to re-write the APP so that it functions in FACEBOOK messenger? Will our developer have to go back into the APP to ADD FACEBOOK MESSENGER script/code? 10. Could you describe in point-form document how to upload our ANDROID APP to the FACEBOOK MESSENGER PLATFORM? 11. Would you be able to walk us through uploading the APP from our PC (via skype SCREEN SHOT video chat) onto FACEBOOK MESSENGER? (THIS WILL BE FOR AN EXTRA $40 usd, AFTER YOU COMPLETE THE CURRENT PROJECT) Thank you, and look forward to hearing back from all you.
