  • Is this a question how to program your android phone?

  • Not necessarily as I think there are a number of apps available to do this kind of thing -- you should search the playstore for "Raspberry Pi". There's also stuff like nodered which can provide a device agnostic web interface.

I would use MQTT if you are just building the app for yourself. Here is an app on the Playstore MQTT Dash you could try a public MQTT Broker to publish sensor data and subscribe with with app from the app store.

If you are using Python on the Pi you can use Paho to publish your data. Once this is working you can add MQTT to your Android app. Then you have to decide where you want to host the MQTT broker. You could host it on the Pi. Here is a broker you can try Mosquitto.
