BroadcastReceiver for Internet checking

Question

I have Broadcast Receiver for doing Internet checking. Every time device is not connected with Internet, always getting 2 output. I just want one output.

BroadcastReceiver

public class Broadcast extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    ConnectivityManager cm =
            (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null && activeNetwork.isConnectedOrConnecting();
    if (!isConnected){
        Log.i("INTERNET","------------------------- not connect");
    }
}

}

And this is the output

12659-12659 I/ViewRootImpl: CPU Rendering VSync enable = true
12659-12659 I/ViewRootImpl: CPU Rendering VSync enable = true
12659-12701 V/RenderScript: Application requested CPU execution
12659-12701 V/RenderScript: 0xb8116c40 Launching thread(s), CPUs 4
12659-12659 I/INTERNET: ------------------------- not connect
12659-12659 I/INTERNET: ------------------------- not connect

Have you add permission internet in manifest? – A Dev May 18 '17 at 10:57 — A Dev, May 18 '17 at 10:57

Where do you register the `BroadcastReceiver`? – aborocz May 18 '17 at 10:59 — aborocz, May 18 '17 at 10:59

try this

create one class

public class ConnectivityReceiver extends BroadcastReceiver {

public static ConnectivityReceiverListener connectivityReceiverListener;

public ConnectivityReceiver() {
    super();
}

@Override
public void onReceive(Context context, Intent arg1) {
    ConnectivityManager cm = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null
            && activeNetwork.isConnectedOrConnecting();

    if (connectivityReceiverListener != null) {
        connectivityReceiverListener.onNetworkConnectionChanged(isConnected);
    }
}

public static boolean isConnected() {
    ConnectivityManager
            cm = (ConnectivityManager) MyApplication.getInstance().getApplicationContext()
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    return activeNetwork != null
            && activeNetwork.isConnectedOrConnecting();
}


public interface ConnectivityReceiverListener {
    void onNetworkConnectionChanged(boolean isConnected);
}

}

create one another class

public class MyApplication extends Application {

private static MyApplication mInstance;



@Override
public void onCreate() {
    super.onCreate();
    mInstance = this;
}

public static synchronized MyApplication getInstance() {
    return mInstance;
}

public void setConnectivityListener(ConnectivityReceiver.ConnectivityReceiverListener listener) {
    ConnectivityReceiver.connectivityReceiverListener = listener;
}

}

add permisiion in maenfiest file

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

**and this **

**

and dont forget to add this in manifiest

 <receiver
        android:name="com.ncrypted.redfox.Utils.ConnectivityReceiver"
        android:enabled="true">
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
        </intent-filter>
    </receiver>

now call the where you want to check internet like this

implement this in your activity

 ConnectivityReceiver.ConnectivityReceiverListener

 @Override
public void onNetworkConnectionChanged(boolean isConnected) {
    showSnack(isConnected);
}
 private void showSnack(boolean isConnected) {
    if (isConnected) {
        getUserStatus();
    } else {
        Toast.makeText(this, getString(R.string.str_internet_err), Toast.LENGTH_SHORT).show();
    }
}

You can check Network availability without Broadcast Receiver.

public class ConnectivityUtils {
private final Activity mActivity;

public ConnectivityUtils(Activity mActivity) {
    this.mActivity = mActivity;
}

public  boolean getConnectivityStatus() {
    ConnectivityManager cm = (ConnectivityManager) mActivity
            .getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    return null != activeNetwork;
}
}

Add in AndroidManifest.xml

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

BroadcastReceiver for Internet checking

BroadcastReceiver

And this is the output
