Ini adalah contoh bagaimana untuk mengetahui status jaringan internet di android menggunakan ConnectivityManager dan NetworkInfo

Langkah 1 - Buka android studio dan buat project baru

Langkah 2 − pada file manifest.xml android.permission.ACCESS_NETWORK_STATE

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="id.karnadi.myapplication">

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Langkah 3 - Tulis kode ini ke dalam file main_activity.java

package id.karnadi.myapplication;

import androidx.appcompat.app.AppCompatActivity;

import android.app.Service;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    Button btnCheck;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnCheck = findViewById(R.id.buttonCheck);

        btnCheck.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                check();
            }
        });

    }

    private void check(){
        String status = "NO CONNECTION";
        ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Service.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

        if(networkInfo != null && networkInfo.isConnected()){
            if(networkInfo.getType() == connectivityManager.TYPE_WIFI){
                status = "WIFI CONNECTED";
            } else if (networkInfo.getType() == connectivityManager.TYPE_MOBILE){
                status = "MOBILE CONNECTED";
            }
        }
        Toast.makeText(this,status,Toast.LENGTH_LONG).show();
    }
}

Langkah 4 - pada file layout activity_main.xml tulis kode seperti ini

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/buttonCheck"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
