Hello , I am trying to develop an application , which will use the internet
throughout the application .The user will be informed when the internet
disconnects or connects . I have searched a lot of codes and tried running
them but I couldn't get them worked .Could anyone give me a hand to use
static broadcast receivers? I am totally new to android .Any help is
appreciated .Thank you ..
Here one of the examples is :

<application

<activity

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

</activity>
<receiver android:name="ConnectionChangeReceiver">
<intent-filter>
<action android:name="com.example.broadcastreceiver"/>
</intent-filter>
</receiver>
</application>
</manifest>
********************************************************************************************
package com.example.broadcastreceiver;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.IntentFilter;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent=new Intent();
intent.setAction("com.example.broadcastreceiver");
sendBroadcast(intent);
}
}
*************************************************************************
package com.example.broadcastreceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;

public class ConnectionChangeReceiver extends BroadcastReceiver
{
@Override
public void onReceive( Context context, Intent intent )
{
ConnectivityManager connectivityManager = (ConnectivityManager)
context.getSystemService( Context.CONNECTIVITY_SERVICE );
NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
NetworkInfo mobNetInfo =
connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE );
if ( activeNetInfo != null )
{
Toast.makeText( context, "Active Network Type : "+
activeNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();
}
if( mobNetInfo != null )
{
Toast.makeText( context, "Mobile Network Type : "+
mobNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();
}
}
}
