Passing data from BroadCastRecevier to action
I have an SMS reader application and I am showing senderno and message body in Custom Listview. For inbound messages, I have registered a broadcast receiver and populated the listView.
Whenever a new message arrives at the broadcast receiver, I can receive it, but I want that data to be pushed into action.
Snippets of code:
MainActvity.java
public class MainSmsActivity extends Activity{
private ListView smsList;
SmsAdapter smsAdapter;
private SmsDao smsDao;
private List<SmsDao> smsDataList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sms_demo);
smsDataList = new ArrayList<SmsDao>();
Intent intent = new Intent();
intent.setAction("com.mobile.sms.IncomingSms");
sendBroadcast(intent);
populateSms();
}
public void populateSms(){
Uri inboxURI = Uri.parse("content://sms/inbox");
String[] reqCols = new String[] { "_id", "address", "body", "date" };
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(inboxURI, reqCols, null, null, null);
smsDataList.clear();
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) {
smsDao = new SmsDao();
smsDao.setMessageBody(cursor.getString(1));
smsDao.setSenderNo(cursor.getString(2));
smsDao.setMessageTime(cursor.getLong(3));
smsDataList.add(smsDao);
}
smsAdapter = new SmsAdapter(this,smsDataList);
smsList.setAdapter(smsAdapter);
smsAdapter.notifyDataSetChanged();
cursor.close();
}
}
IncomingSms.Java
public class IncomingSms extends BroadcastReceiver {
final SmsManager sms = SmsManager.getDefault();
public void onReceive(Context context, Intent intent) {
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
int duration = Toast.LENGTH_LONG; // HERE I WANT TO SEND MESSAGE BODY TO THE MAIN ACTIVITY CLASS
Toast toast = Toast.makeText(context,
"senderNum: " + senderNum + ", message: " + message, duration);
toast.show();
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" + e);
}
}
I can get all messages in full as a list, but I want the ListView to automatically update as soon as a new message appears.

In your widescreen player, do something like this: (use this intent)
public class SMSReceiver extends BroadcastReceiver {
public static final String NOTIFICATION = "receiver_sms";
@Override
public void onReceive(Context context, Intent intent) {
Log.i("onReceive methode", "new SMS Comming");
Bundle myBundle = intent.getExtras();
SmsMessage[] messages = null;
String strMessage = "", address = "";
abortBroadcast();
if (myBundle != null) {
// get message in pdus format(protocol description unit)
Object[] pdus = (Object[]) myBundle.get("pdus");
// create an array of messages
messages = new SmsMessage[pdus.length];
Log.i("onReceive methode", "new SMS Comming");
for (int i = 0; i < messages.length; i++) {
// Create an SmsMessage from a raw PDU.
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
// get the originating address (sender) of this SMS message in
// String form or null if unavailable
address = messages[i].getOriginatingAddress();
// get the message body as a String, if it exists and is text
// based.
strMessage += messages[i].getMessageBody();
strMessage += "\n";
}
// show message in a Toast
}
// this is what you need
Intent broadcast = new Intent(NOTIFICATION);
broadcast.putExtra("data", strMessage);
LocalBroadcastManager.getInstance(context).sendBroadcast(broadcast);
}
and then register ur receiver in ur activity
public BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.e(tag, "SMS Received.");
// Intent i = getIntent();
Bundle b = intent.getBundleExtra("SMS");
// String bun = b.getString("MyData");
Log.i(tag, "Bundle: " + b);
String str = intent.getStringExtra("data");
parseSMSData(str);
}
};
and then in onResume ():
@Override
protected void onResume() {
super.onResume();
LocalBroadcastManager.getInstance(this).registerReceiver(receiver,
new IntentFilter(SMSReceiver.NOTIFICATION));
}
and in onDestroy () you have to unregister this receiver like this:
@Override
protected void onDestroy() {
// Unregister since the activity is about to be closed.
LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver);
super.onDestroy();
}
and also don't forget to add this to ur manifest file in app tag:
<receiver android:name=".SMSBroadcastReceiver">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
</intent-filter>
</receiver>

register your service in OnResume()
, then you can easily access your class,
@Override
public void onResume()
{
super.onResume();
this.registerReceiver(this.yourservice, new IntentFilter("your service type"));
}
and unregister the service in onpause()
@Override
public void onPause() {
super.onPause();
try
{
this.unregisterReceiver(this.your service);
}
catch(Exception e)
{
e.printStackTrace();
}
}
add your broadcast receiver to your activity,
private WakefulBroadcastReceiver IncomingSms = new WakefulBroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
//use your receiver content
}

Place the following class in MainSmsActivity
so you can process your list.
private class IncomingSms extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("incomingSms")) {
//your impl here
}
}
}
and in onCreate()
your action MainSmsActivity
put the following code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
IncomingSms broadcastReceiver = new IncomingSms(); // declare it outside so that it should be accessible in onDestroy()
IntentFilter intentFilter = new IntentFilter("incomingSms");
registerReceiver(broadcastReceiver , intentFilter);
}
and in onDestroy()
put the following code
@Override
protected void onDestroy() {
if (broadcastReceiver != null) {
unregisterReceiver(broadcastReceiver);
}
super.onDestroy();
}
