Internet Connectivity check in Android
<p>I need to check whether internet is available or not in Android, so I have tried using the following function:</p>

<pre><code>boolean b_IsConnect = isNetworkAvailable();
private boolean isNetworkAvailable() {
  ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
  NetworkInfo activeNetworkInfo = connectivityManager
    .getActiveNetworkInfo();
  return activeNetworkInfo != null;
}
</code></pre>

<p>And I also added the required permissions in the manifest:</p>

<pre><code>&lt;uses-permission android:name="android.permission.INTERNET" /&gt;
&lt;uses-permission android:name="android.permission.WAKE_LOCK" /&gt;
&lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
&lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" &gt;
&lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/&gt;
&lt;uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/&gt;
</code></pre>

<p>But it still throws exceptions:</p>
