Requirements

This App was developerd by using Android studio with Java language. To run this App, an Andorid phone with Android Version > 5.0 is needed (we recommend Android 10).

User guide

Before installing this App, please make sure the Java environment and Android studio have been installed on your computer, and you have switched on the developer mode on your Android smartphone (Android Version > 5.0).

The App is the core of this IoT diagnostic platform, it has three functions:

  • Control the mobile heater
  • Communicate with the Blockchain
  • Running the Deeplearning model(CNN)

Because the server used in our study was since turned off, we did not provide an .apk installation package. You may need to run your own server and slightly modify the code.

Once you have your server running you need to change some urls in the source code.

  • In /Assay/app/src/main/java/FetchData.java file line 32 you will find:
Request request = new Resquest.Builder()
    .url("http://xx.xx.xx")+LoginActivity.port+"/api/"+urlPath)
    .build();

Just simply change the url to your server address, e.g.

Request request = new Resquest.Builder()
    ..url("http://localhost:3000")+LoginActivity.port+"/api/"+urlPath)
    .build();
  • In /Assay/app/src/main/java/DevInfoManufacturerActivity.java file line 133 change the url to your server address, e.g.

From

Request request = new Resquest.Builder()
    .url("http://xx.xx.xx")+LoginActivity.port+"/api/ProduceDevice")
    .build();

To

Request request = new Resquest.Builder()
    ..url("http://localhost:3000")+LoginActivity.port+"/api//api/ProduceDevice")
    .build();

And you need to change the urls in /Assay/app/src/main/java/LoginActicaty.java line 22 and /Assay/app/src/main/java/PatientInfoActivity.java line 200 to your blockchain rest server address in the same way.

An firebase storage was used for saving the images during the test, if you want to use your own bucket you will need to modify the CustomCamActivity.java and PatientInfoActivity.java. Details please see Firebase documentation.
