I want to send message to multiple numbers. I tried to use SMS manager. But it's not working.
I am doing it onPostExecute method of an AsyncTask. But I want to create a service and send messages from that service because user can close the application before messages sending gets complete so it should be working in background.
I have created a arraylist of numbers. Now this I want to send to service and send message to each number.
My attempt:
@Override
public void doPostExecute(JSONArray response) throws JSONException {
ArrayList<String> numbers = new ArrayList<>();
for (int i = 0; i < response.length(); i++) {
JSONObject subObject1 = response.getJSONObject(i);
String status = subObject1.getString("status");
if (status.equals("1")) {
JSONObject invitation = subObject1.getJSONObject("invitation");
String number = invitation.getString("invitee_no");
numbers.add(number);
} else {
}
}
try {
SmsManager sms = SmsManager.getDefault();
PendingIntent sentPI;
String SENT = "SMS_SENT";
sentPI = PendingIntent.getBroadcast(InviteContactsActivity.this, 0,new Intent(SENT), 0);
sms.sendTextMessage(phoneNumber, null, message, sentPI, null);
sms.sendTextMessage("8655864341", null, "Hi,add me to your unique contact list.",sentPI, null);
} catch (Exception e) {
e.printStackTrace();
}
}
I have added permission for send sms in manifest.
<uses-permission android:name="android.permission.SEND_SMS"/>
How can I do this? Can anyone help please? Thank you..
EDIT:
I tried to write service like below:
public class MessageService extends Service {
ArrayList<String> numbers = new ArrayList<>();
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
numbers = intent.getStringArrayListExtra("numbers");
for(int i=0;i<numbers.size();i++) {
sendMsg(numbers.get(i));
}
return super.onStartCommand(intent, flags, startId);
}
public void sendMsg(final String num){
String SENT = "SMS_SENT";
final SmsManager sms = SmsManager.getDefault();
final PendingIntent sentPI = PendingIntent.getBroadcast(MessageService.this, 0,new Intent(SENT), 0);
Handler h = new Handler();
h.postDelayed(new Runnable() {
@Override
public void run() {
sms.sendTextMessage("8655864341", null, "Hi MyApp SMS", sentPI, null);
}
}, 2000);
}
@Override
public IBinder onBind(Intent intent)
{
// numbers = intent.getStringArrayListExtra("numbers");
return null;
}
}
And calling it from an activity:
Intent serviceIntent = new Intent(this,MessageService.class);
serviceIntent.putStringArrayListExtra("numbers",numbers);
startService(serviceIntent);
Added service in manifest:
<uses-permission android:name="android.permission.SEND_SMS" />
<receiver android:name=".SmsSentReceiver"/> <receiver android:name=".SmsDeliveredReceiver"/>
<service android:name=".helper.MessageService"></service>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".Activities.MainActivity" />
But as I do debug and check service is not getting called.
What's going wrong?
EDIT :
Tried this way with broadcast receiver :
public class MessageService extends Service {
ArrayList<String> numbers = new ArrayList<>();
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
numbers = intent.getStringArrayListExtra("numbers");
for (String number:numbers) {
sendSMS("8655864341","Hello");
}
// sendMsg(numbers.get(i));
return super.onStartCommand(intent, flags, startId);
}
public void sendMsg(final String num){
String SENT = "SMS_SENT";
final SmsManager sms = SmsManager.getDefault();
final PendingIntent sentPI = PendingIntent.getBroadcast(MessageService.this, 0,new Intent(SENT), 0);
Handler h = new Handler();
h.postDelayed(new Runnable() {
@Override
public void run() {
sms.sendTextMessage("7303668514", null, "Hi MyApp SMS", sentPI, null);
}
}, 2000);
}
@Override
public IBinder onBind(Intent intent)
{
// numbers = intent.getStringArrayListExtra("numbers");
return null;
}
private void sendSMS (String phoneNumber, String message){
ArrayList<PendingIntent> sentPendingIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> deliveredPendingIntents = new ArrayList<PendingIntent>();
PendingIntent sentPI = PendingIntent.getBroadcast(getApplicationContext(), 0,
new Intent(getApplicationContext(), SmsSentReceiver.class), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0,
new Intent(getApplicationContext(), SmsDeliveredReceiver.class), 0);
try {
SmsManager sms = SmsManager.getDefault();
ArrayList<String> mSMSMessage = sms.divideMessage(message);
for (int i = 0; i < mSMSMessage.size(); i++) {
sentPendingIntents.add(i, sentPI);
deliveredPendingIntents.add(i, deliveredPI);
}
sms.sendMultipartTextMessage(phoneNumber, null, mSMSMessage,
sentPendingIntents, deliveredPendingIntents);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getBaseContext(), "SMS sending failed...", Toast.LENGTH_SHORT).show();
}
}
public class SmsDeliveredReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(context, "SMS delivered", Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(context, "SMS not delivered", Toast.LENGTH_SHORT).show();
break;
}
}
}
public class SmsSentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(context, "SMS Sent", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(context, "SMS generic failure", Toast.LENGTH_SHORT)
.show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(context, "SMS no service", Toast.LENGTH_SHORT)
.show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(context, "SMS null PDU", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(context, "SMS radio off", Toast.LENGTH_SHORT).show();
break;
}
}
}
Getting this exception:
java.lang.RuntimeException: Unable to instantiate receiver com.example.siddhi.contactsapp.helper.MessageService$SmsSentReceiver: java.lang.InstantiationException: class com.example.siddhi.contactsapp.helper.MessageService$SmsSentReceiver has no zero argument constructor
Not getting message..
You can do something like this :
Use a for loop for your Numbers list and inside that Use a handler to maintain some time gap between each sent message, say 2 seconds and send the message.
OR
You can define a Broadcast Receiver inside your Service which will check for the Message Delivery Report and if Delivered then send another Message.
Hope it Helps :)
Edit :
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
ArrayList<String> numberlist=new ArrayList<String>();
for(int i=0;i<numberlist.size();i++) {
sendMsg(numberlist.get(i));
}
return super.onStartCommand(intent, flags, startId);
}
public void sendMsg(final String num){
String SENT = "SMS_SENT";
final SmsManager sms = SmsManager.getDefault();
final PendingIntent sentPI = PendingIntent.getBroadcast(MyService.this, 0,new Intent(SENT), 0);
Handler h = new Handler();
h.postDelayed(new Runnable() {
@Override
public void run() {
sms.sendTextMessage(num, null, "Hi MyApp SMS", sentPI, null);
}
}, 2000);
}
