将意图发送到短信应用Android 4.4及更高版本

Question

I'm using this code to send intent default sms app in my application

Intent smsIntent = new Intent(Intent.ACTION_VIEW);
        smsIntent.setType("vnd.android-dir/mms-sms");
        smsIntent.putExtra("address", number);
        smsIntent.putExtra("sms_body",message);

        if (smsIntent.resolveActivity(context.getPackageManager()) != null) {
            context.startActivity(smsIntent);
        }

This code open an sms app in android 5 (and probably in kitkat!) but it may or may not be the default sms app! So sometimes when it does not open default sms app i get an error because only default app can send sms!

my question is how to insure only default app handles my intents ?

Answer 1

try adding this-

smsIntent.addCategory(Intent.CATEGORY_DEFAULT); 

this should ensure the recipient app is the default one.

Or alternatively for KK, you could try this-

SmsManager.getDefault().sendTextMessage("Phone Number", null, "Message", null, null);

NB: Using this method requires that your app has the SEND_SMS permission.
