Mobile number will be entered in an edittext by user on registration page in my Android application. How can I check that user entered his/her mobile number not other's ?
I've tried this :
TelephonyManager tMgr =(TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
mPhoneNumber = tMgr.getLine1Number();
And compare this variable with edittext's text. But mPhoneNumber returns NULL in my case. Is there any other options? How to solve this ?
Any help would be appreciable.
I have tried this : Check source code :
public class MainActivity extends Activity{
Button submit;
EditText contact;
String phNo;
ProgressDialog progress;
@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);
submit.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
phNo = contact.getText().toString();
new CheckOwnMobileNumber().execute();
Toast.makeText(getApplicationContext(), phNo, Toast.LENGTH_LONG).show();
}
});
}
private class CheckOwnMobileNumber extends AsyncTask<String, Void, String>
{
@Override
protected void onPostExecute(String result)
{
// TODO Auto-generated method stub
if(progress.isShowing())
{
progress.dismiss();
// Check SMS Received or not after that open dialog date
/*if(SMSReceiver.str.equals(phNo))
{
Toast.makeText(getApplicationContext(), "Thanks for providing your number.", Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "Provide your own mobile number please.", Toast.LENGTH_LONG).show();
return;
}*/
}
}
@Override
protected String doInBackground(String... params)
{
// TODO Auto-generated method stub
String msg = phNo;
try
{
sendSMS(phNo, msg);
}
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 void sendSMS(String phoneNumber, String message)
{
//PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0, new Intent(getApplicationContext(), MainActivity.class), 0);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, null, null);
}
}
Receiver to listen SMS received or not ?
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;
// Retrieve SMS
public void onReceive(Context context, Intent intent) {
mContext = context;
mIntent = intent;
String action = intent.getAction();
if(action.equals(ACTION_SMS_RECEIVED))
{
SmsMessage[] msgs = getMessagesFromIntent(mIntent);
if (msgs != null)
{
for (int i = 0; i < msgs.length; i++)
{
address = msgs[i].getOriginatingAddress();
str = msgs[i].getMessageBody().toString();
}
}
// ---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;
}
}
