java – CONNECTIVITY_ACTION Broadcast receiver not working-ThrowExceptions

Exception or error:

This is my broadcast receiver. I have added all the details that were required but still it is not working

 import android.content.BroadcastReceiver;
 import android.content.Context;
 import android.content.Intent; 
 import android.net.ConnectivityManager;
 import android.net.NetworkInfo;
 import android.util.Log;
 import android.widget.Toast;

public class myBroadCastReceiver extends BroadcastReceiver {

@Override
public void onReceive(final Context context, final Intent intent) {
    ConnectivityManager connectivityManager = 
    (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE );
    NetworkInfo activeNetInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
    boolean isConnected = activeNetInfo != null && activeNetInfo.isConnectedOrConnecting();
    if (isConnected)
        Log.i("NET", "Connected" + isConnected);
    else
        Log.i("NET", "Not Connected" + isConnected);
     }
 }

and the manifest file as, I have added all the details the were required but still it is not working

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

<uses-permission android:name="android.permission.INTERNET"/>
<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"
    tools:ignore="GoogleAppIndexingWarning">
    <receiver android:name=".myBroadCastReceiver" android:enabled="true">
        <intent-filter>

            <action android:name="android.net.conn.CONNECTIVITY_CHANGE"></action>
        </intent-filter>

     </receiver>

    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

I have worked everything out but this is not working, any idea what can be missing, I have not made a change in MainActivity.java , could that be the reason?

How to solve:

Apps targeting Android 7.0 and higher must register the CONNECTIVITY_ACTION broadcast using Context.registerReceiver(BroadcastReceiver, IntentFilter). (source)

You can’t register it in your manifest, because then your app would wake up every time the user’s connectivity changes, which is awful for performance and battery life.
