Blog #8: Monitoring Recycling Factory, IoT and Employees Health on Android App Google Play Store

I have developed Android App 'E14 Upcycle IoT Demo' which is also uploaded on my Google Play Store. 

Google PlayStore Name : 

Applet is also uploaded on e14 :  e14upcycleiotdemo_apk, e14upcycleiotdemo_app.zip

Android Applet Name :  E14 Upcycle IoT Demo

Software Used :  Android Studio Hedgehog | 2023.1.1 Patch 2, on Linux(64-bit).

Andriod Versions Supported 

Minimum : Android 4.4, KitKat

Latest : Android 14.0, UpsideDownCake

API Level    Min : 19  and Latest : 34

Language  :  Java, XML

Gradle : 8.2

Description of Applet : This applet is for DEMO purposes only, designed as a part of the contest 'Upcycle IoT Design Challenge' held by element14.com.Using this app, the owner, and senior management can view complete factory status, activities, all major/minor updates on its 'Factory Dashboard', which includes Electrical Room MCCB voltages, current & power readings; Inventory; Scrap; Recycle Room 1; Recycle Room 2; Recycle Room 3; DG,Solar,Wind; R and D ; Inventory R and D ; Training; Logistics; Account; Business Room; Alliancesand Blacklist.

The owner and senior management can also login and monitor 32 employees which include security guards, maintenance engineer, technician, engineer, helper, workers, etc. Not only this, they can remotely switch ON/OFF airpurifers when the factory air quality index falls below normal values. It is a must as the recycling makes companies employees expose to toxic, and the owner do not want its employees to get affected by this recycling process.

You can enjoy turning on/off button of airpurifier and from dashbaord-business room.

username is user

password is 1234

This applet lacks security features, cryptography not implemented in this app.

2. Code Snippets 

Following are not pseduo codes, but working codes with few lines omitted as elementary for any grad. Code is known and it can be known by reverse engineering,

1)

//Created by Mr. Abhishek Bansal

 public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
    private DrawerLayout drawerLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         setSupportActionBar(toolbar);
         
         
         Override
    public void onBackPressed() {
        if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
            drawerLayout.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }

public class NotificationReceiver extends BroadcastReceiver {

        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, nextActivity, 0);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "")
                .setSmallIcon(R.drawable.notification)

                .setContentIntent(pendingIntent);
        NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(context);


        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.POST_NOTIFICATIONS) != PackageManager.PERMISSION_GRANTED) {
             
            return;
