Checking for the presence of an Internet connection on an Android device

Checking for the presence of an Internet connection on an Android device

See Here in main.xml file here I am taking a button, when you click the button it will check internet is connected or not.

Your AndroidManifest.xml will need to include the following permission;

    <uses-permission android:name="android.permission.INTERNET"/>

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="internet.connection"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-permission android:name="android.permission.INTERNET" />

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE />

    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name" >

        <activity

            android:name=".TestInternetConnectionActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

Main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/hello" />

    <RelativeLayout

        android:id="@+id/relativeLayout1"

        android:layout_width="match_parent"

        android:layout_height="wrap_content" >

        <Button

            android:id="@+id/button1"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_alignParentTop="true"

            android:layout_centerHorizontal="true"

            android:onClick="myClickHandler"

            android:text="Internet Test" />

    </RelativeLayout>

</LinearLayout>

TestInternetActivity.java

public class TestInternetActivity extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

       

        Button btn = (Button)findViewById(R.id.button1);

    }

   

    public void myClickHandler(View view)

    {

      ConnectivityManager connMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);

      NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();

      if (networkInfo != null && networkInfo.isConnected())

      {

        

            Toast.makeText(getApplicationContext(), "You are Connected in Internet", Toast.LENGTH_LONG).show();

           

        } else

        {

            Toast.makeText(getApplicationContext(), "No Internet Connection", Toast.LENGTH_LONG).show();

        

        }

    }

}
