Applab is built with PHP and native Java. It's an android app generator. Admin can set up the configuration form backend. Admin is able to generate the configuration file in two ways. 1. By generating the config file, 2. By the APIs. To use the first method admin have to paste the config folder in the project in android studio. Admin doesn't need to upload the backend to live server. Admin can generate the config file form localhost. For the second method, admin has to put the API link and API token in the setting page in android studio. To use this method admin have to upload the backend to a live server.
