How can I send sms messages in the BACKGROUND using Android?
I am coming from iphone development where you cannot send an SMS in the background without asking the user to confirm the send. Can sms be sent in 开发者_运维问答the background in android so that no user intervention is need?
Send SMS with SMS-Delivery notification as toast.
method call as below.
sendSMS("98********","This is test message");
method signature as below.
/*
* BroadcastReceiver mBrSend; BroadcastReceiver mBrReceive;
*/
private void sendSMS(String phoneNumber, String message) {
ArrayList<PendingIntent> sentPendingIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> deliveredPendingIntents = new ArrayList<PendingIntent>();
PendingIntent sentPI = PendingIntent.getBroadcast(mContext, 0,
new Intent(mContext, SmsSentReceiver.class), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(mContext, 0,
new Intent(mContext, 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();
}
}
Now two more classes SmsDeliveredReceiver,SmsSentReceiver as below.
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;
}
}
}
Now SmsSentReceiver.
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;
}
}
}
Now Permissions open your AndroidManifest.xml and add below line
<uses-permission android:name="android.permission.SEND_SMS"/>
and its done.......
Yes, you can do it by using:
SmsManager sm = SmsManager.getDefault();
sm.sendTextMessage(number, null, message, null, null);
Best answer is good but above API level 23 you will need to get the permission pragmatically. Otherwise permission will be prompted each time.
private static final int PERMISSION_REQUEST_CODE = 1;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.SEND_SMS)
== PackageManager.PERMISSION_DENIED) {
Log.d("permission", "permission denied to SEND_SMS - requesting it");
String[] permissions = {Manifest.permission.SEND_SMS};
requestPermissions(permissions, PERMISSION_REQUEST_CODE);
}
}
