Android App

You can find a simple Android App in this repo, which access the NodeMCU Server to display the files on the SD Card. The App is just for learning purpose, but can be a good start for your own project. Anroid_App_NODEMCU



You will have to change the IP of the NodeMCU Server in the App code, as there is currently no interface to do that from within the App.

You can change the NodeUrl in the MainActivity.java

  String nodeURL = "http://192.168.0.2/";
