In this android example, we will see how to Detect Connected Network Type either Mobile or WIFI in Android Studio by using Kotlin Language. Step 1: Create a new Project in android studio. Go to File > New > New Project > Empty Activity > Next > Enter Name > Select Language Kotlin > Finish Step 2: Go to activity_main.xml file and add the following code <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" <TextView <Button Step 3: Add permission to the AndroidManifest.xml file above tag. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> Step 4: Open MainActivity.kt file and add the following code. lateinit var type : TextView check.setOnClickListener{ } // type.text = networkInfo!!.typeName Step 5: Run the app on emulator or real device, you will get the output as in Video activity_main.xml file <?xml version="1.0" encoding="utf-8"?> <TextView <Button MainActivity.kt file import android.content.Context class MainActivity : AppCompatActivity() { check.setOnClickListener{ } // type.text = networkInfo!!.typeName AndroidManifest.xml file <?xml version="1.0" encoding="utf-8"?> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <category android:name="android.intent.category.LAUNCHER" /> Conclusion: In this article we have covered how to detect connected network type in Android Studio by using Kotlin Language.
