I am preparing an app which requires me to have user's phone number and then send a hashcode the user programatically as SMS so that it will be used as their token afterwards.
I am making the user enter the number in the MainActivty and have my receiver which listens to SMS_RECEIVED so that it will notiy the user, first of all I want to make sure I am sending and receiving the user's number correctly and receving it. However my receiver does not seems to listen to the trigger. I can see the received sms on notification as well as I can hear the sound but broadcast receiver does not listens to it.
My Code for MainActivity is
public class MainActivity extends Activity
{
Button submit;
EditText contact;
static String phNo;
ProgressDialog progress;
static Boolean wasMyOwnNumber;
static Boolean workDone;
final static int SMS_ROUNDTRIP_TIMOUT = 30000;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
contact = (EditText)findViewById(R.id.mobileNumber);
submit = (Button) findViewById(R.id.button1);
wasMyOwnNumber = false;
workDone = false;
submit.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
phNo = contact.getText().toString();
new CheckOwnMobileNumber().execute();
}
});
}
private class CheckOwnMobileNumber extends AsyncTask<String, Void, String>
{
@Override
protected void onPostExecute(String result)
{
// TODO Auto-generated method stub
if(progress.isShowing())
{
progress.dismiss();
if(wasMyOwnNumber)
{
Toast.makeText(getApplicationContext(), "Number matched.", Toast.LENGTH_LONG).show();
wasMyOwnNumber = false;
workDone = false;
}
else
{
Toast.makeText(getApplicationContext(), "Wrong number.", Toast.LENGTH_LONG).show();
wasMyOwnNumber = false;
workDone = false;
return;
}
}
super.onPostExecute(result);
}
@Override
protected String doInBackground(String... params)
{
// TODO Auto-generated method stub
String msg = phNo;
try
{
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phNo, null, msg, null, null);
timeout();
}
catch(Exception ex)
{
Log.v("Exception :", ""+ex);
}
return null;
}
@Override
protected void onPreExecute()
{
// TODO Auto-generated method stub
progress = ProgressDialog.show(MainActivity.this, "","Checking Mobile Number...");
progress.setIndeterminate(true);
progress.getWindow().setLayout(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
super.onPreExecute();
}
}
private boolean timeout()
{
int waited = 0;
while (waited < SMS_ROUNDTRIP_TIMOUT)
{
try
{
Thread.sleep(100);
}
catch (InterruptedException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
waited += 100;
if(phoneNumberConfirmationReceived())
{
waited=SMS_ROUNDTRIP_TIMOUT;
workDone = true;
}
}
/*Log.v("MainActivity:timeout2: Waited: " , ""+waited);
Log.v("MainActivity:timeout2:Comparision: ", ""+ phoneNumberConfirmationReceived());
Log.v("MainActivity:timeout2: WorkDone value after wait complete : ", ""+workDone);*/
return workDone;
}
private boolean phoneNumberConfirmationReceived()
{
if(wasMyOwnNumber)
{
workDone = true;
}
return workDone;
} MyCode for SMSReceiver is
public class SMSReceiver extends BroadcastReceiver
{
private static final String ACTION_SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
Context mContext;
private Intent mIntent;
static String address, str = null;
boolean isSame;
// Retrieve SMS
public void onReceive(Context context, Intent intent)
{
Log.v("ONMESSAGE", "RECEIVED");
mContext = context;
mIntent = intent;
String action = intent.getAction();
SmsMessage[] msgs = getMessagesFromIntent(mIntent);
if (msgs != null)
{
for (int i = 0; i < msgs.length; i++)
{
address = msgs[i].getOriginatingAddress();
str = msgs[i].getMessageBody().toString();
}
}
Log.v("Originating Address : Sender :", ""+address);
Log.v("Message from sender :", ""+str);
isSame = PhoneNumberUtils.compare(str, MainActivity.phNo);
Log.v("Comparison :", "Yes this true. "+isSame);
if(isSame)
{
MainActivity.wasMyOwnNumber = isSame;
MainActivity.workDone=true;
}
// ---send a broadcast intent to update the SMS received in the
// activity---
Intent broadcastIntent = new Intent();
broadcastIntent.setAction("SMS_RECEIVED_ACTION");
broadcastIntent.putExtra("sms", str);
context.sendBroadcast(broadcastIntent);
}
public static SmsMessage[] getMessagesFromIntent(Intent intent)
{
Object[] messages = (Object[]) intent.getSerializableExtra("pdus");
byte[][] pduObjs = new byte[messages.length][];
for (int i = 0; i < messages.length; i++)
{
pduObjs[i] = (byte[]) messages[i];
}
byte[][] pdus = new byte[pduObjs.length][];
int pduCount = pdus.length;
SmsMessage[] msgs = new SmsMessage[pduCount];
for (int i = 0; i < pduCount; i++)
{
pdus[i] = pduObjs[i];
msgs[i] = SmsMessage.createFromPdu(pdus[i]);
}
return msgs;
}
}

Give a priority value for the intent..
change your <intent-filter> as following
<intent-filter android:priority="999" >
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
Have a try..
Also add permission to receive sms
<uses-permission android:name="android.permission.RECEIVE_SMS" />
