From a previous developer i have json rest service running in PHP that compiles and create android/ios app i want you to finish the json rest webservice, in the server i send in the request a json structure with the app initialization params and the webservice must return in the response the url to donwload the app in the native ios or android also in json format( here is a basic rough prototype for the service request, response , https://www.dropbox.com/s/7ux30hunk3m3ult/InputOutput.png?dl=0 the 1) is the service request, and the 3) is the service response ),
The ui layout structure will be static and based on a predefined template as seen here https://www.dropbox.com/s/t7vm4qwt9ualsd7/coffe_mobile.jpg?dl=0 , only will change the tiltes,color,logo and features based on the request params.
The service must also provide a 'preview' method, returning a image url /base64 about how the app will look with the current parameters( logo , title, bg color etc). Ill provide you the json request detailed structure when the job starts, the one from the above from the provided picture is just a basic demo to make you understand what will be request and response and the final deliverable you must create for the project, this json request for the service will have logo, color, authentication schema, title a nd other custom basic params and a list of dynamic features( scan qr code, contact us, event subscriptions , news, comments, cms( its custom pages with dynamic content that is stored in another remote backend, so the app mus render always the updated dyamic content ).
The features in the app ( scan qr code, contact us, event subscriptions , news, comments, other, cms( its custom pages with dynamic content from other backend ), must be implemented using a factory pattern , a brief description here https://en.wikipedia.org/wiki/Factory_method_pattern , i wil give you the detailed instruction and an example for this factory, this is mandatory
