    <p>Some days ago I found a code in a Stackoverflow post to know when the connectivity of my device changes using a Broadcast Receiver. I adapted it to my application and it works, but everytime I turn on/off my internet connection, the onReceive method on my receiver is called twice. Why is that? My application works fine anyway, but I do some actions twice when once is enough.</p> <p>This is my receiver:</p> <pre><code>public class ConnectivityReceiver extends BroadcastReceiver { private Context mContext; Thread network_check = new Thread(new Runnable(){ public void run() { if (NetworkHelper.isOnline(mContext)) { // Do some stuff } } }); @Override public void onReceive(Context context, Intent intent) { Log.d("MonitorInternetConnectivity", "onReceive"); mContext = context; network_check.start(); } } </code></pre> <p>Network Helper class:</p> <pre><code>public class NetworkHelper { public static boolean isOnline(Context context) { ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo netInfo = cm.getActiveNetworkInfo(); if (netInfo != null &amp;&amp; netInfo.isConnectedOrConnecting() &amp;&amp; canHit()) { return true; } return false; } public static boolean canHit() { try { URL url = new URL("http://www.google.com/"); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.setConnectTimeout(3000); urlConnection.connect(); urlConnection.disconnect(); return true; } catch (Exception e) { e.printStackTrace(); return false; } } } </code></pre> <p>And I added this to my manifest (and the needed permissions):</p> <pre><code>&lt;receiver android:name=".receivers.ConnectivityReceiver" android:exported="false"&gt; &lt;intent-filter&gt; &lt;action android:name="android.net.conn.CONNECTIVITY_CHANGE" /&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; </code></pre> <p>Everytime my connection changes the log shows "onReceive" twice. Why?</p> <p>Thanks!</p> <p>--------------- EDIT ---------------------</p> <p>I add info about the intents received. Everytime the connectivity changes the two intents received are exactly the same.</p> <p>When the device goes offline:</p> <pre><code>Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x10000010 cmp=com.pfc.app/.receivers.ConnectivityReceiver (has extras) } Extras: NetworkInfo: type: WIFI[], state: DISCONNECTED/DISCONNECTED, reason: (unspecified), extra: (none), roaming: false, failover: false, isAvailable: false noConnectivity: true inetCondition: 0 </code></pre> <p>When the device goes online:</p> <pre><code>Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x10000010 cmp=pfc.dani.palou/.receivers.ConnectivityReceiver (has extras) } Extras: NetworkInfo: type: WIFI[], state: CONNECTED/CONNECTED, reason: (unspecified), extra: (none), roaming: false, failover: false, isAvailable: true inetCondition: 0 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
