Android Class for IoT device Provisioning

Hi! Thank you for you time, i'm starting an IoT startup and already have an android APP. Looking for who want to help me and join our team with a awesome work. My needs is: In one of my app menus, the user will register a new device. This device is an sensor with MCU (esp32 for example), which will be available as wifi hotspot, named "Company ??????". I need a new activity to scan wifi networks that the name starts with "Company". If found a network single network, it is necessary to connect with a hardcoded password and execute a HTTPS GET request for a REST API - if found more than one, display a list to the user choose and go - , something like [login to view URL], which will return a JSON payload like { "device": { "id": "company_??????"} ...}. This device id ?????? needs to be parsed and assigned to a string, which after success will ask the id, which is available in the in the product box. If success, a new activity will ask user a wifi name and password, store to a variable and pass to a new RPC call (something like [login to view URL]) with a JSON payload like { "wifi": { "sta": { "ssid": "$ssidvariable", "password": "$pwd" } } }. Another calls to RPC will be needed to disable AP-mode, reboot the device, and insert some metadata to google firebase and etc. If everything ok, the device will reboot, disable the ap-mode, and communicate to the cloud. So validate if the connection with the cloud is ok with a firebase query and show user a new activity for device activation success. I will share full details.
