Activity Code

package com.example.studyreceiver;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;public class MainActivity extends Activity implements OnClickListener {    NetworkReceiver mReceiver;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        // Intent intent = getIntent();        // String data = intent.getStringExtra("data");        if (mReceiver != null) {            // unregisterReceiver(mReceiver);        }    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }    @Override    public void onClick(View v) {        switch (v.getId()) {        case R.id.register_receiver:            this.startService(new Intent(this, ServiceDemo.class));            break;        default:            break;        }    }}

Service Code:

package com.example.studyreceiver;import android.app.Service;import android.content.Intent;import android.content.IntentFilter;import android.net.ConnectivityManager;import android.os.IBinder;public class ServiceDemo extends Service {    NetworkReceiver mReceiver;    @Override    public IBinder onBind(Intent intent) {        return null;    }    @Override    public void onCreate() {        super.onCreate();        IntentFilter filter = new IntentFilter(                ConnectivityManager.CONNECTIVITY_ACTION);        NetworkReceiver mReceiver = new NetworkReceiver();        registerReceiver(mReceiver, filter);    }    @Override    public void onDestroy() {        super.onDestroy();        unregisterReceiver(mReceiver);    }}

 

Receiver code:

Package COM. example. studycycler; import android. app. notification; import android. app. icationicationmanager; import android. app. pendingintent; import android. content. broadcastreceiver; import android. content. context; import android. content. intent; import android.net. connectivitymanager; import android.net. networkinfo; import android. widget. toast; public class networkreceiver extends broadcastreceiver {protec Ted context mcontext; @ override public void onreceive (context, intent) {mcontext = context; Method1 (); // method2 (intent);} private void Method1 () {// first connectivitymanager = (connectivitymanager) mcontext. getsystemservice (context. connectivity_service); networkinfo mobilenetinfo = connectivitymanager. getnetworkinfo (connectivitymanager. type_mobile); Network Info wifinetinfo = connectivitymanager. getnetworkinfo (connectivitymanager. type_wifi); If (! Mobilenetinfo. isconnected ()&&!
