android - (Android)为什么我使用SmsManager.getDefault()。sendTextMessage但应用程序不发送短信？

我使用了SmsManager.getDefault（）。sendTextMessage但未发送短信，我想以编程方式发送短信，请参见以下代码

编辑代码：

    public void sendEmail(View view){
            if (hasConnection() == false){
                Intent goPop = new Intent(getApplicationContext(),ShowPopup.class);
                startActivity(goPop);
                finish();
            }
            statusOfGPS = mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

            // Set Email option
            final Intent i = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",OpsEmail, null));


            //Check Send SMS
            if (mSMSCheckbox.isChecked()){
                SMS = true;
            }else{
                SMS = false;
            }

            //Check GPs
            if (statusOfGPS == true){
                LocationBy = "GPS";

            }else{
                LocationBy = "INTERNET";
            }
            setUpAddress();
            //SMS true
            if (mLocationClient != null && mLocationClient.isConnected() && SMS == true) {
                //set massage to send
                DescribeText = "This is a Emergency message \n\n PLEASE HELP ME!!! at\n\n "+
                        addressText+ "\n Location("+LocationBy+"):("+mLocationClient.getLastLocation().getLatitude() + mLocationClient.getLastLocation().getLongitude()+
                        ") \n\n Please check maps <a href='https://maps.google.com/maps?q="+mLocationClient.getLastLocation().getLatitude()+","+mLocationClient.getLastLocation().getLongitude()+"&ll="+mLocationClient.getLastLocation().getLatitude()+","+mLocationClient.getLastLocation().getLongitude()+"&z=17'>here</a>";

                //send SMS First
                String sent = "android.telephony.SmsManager.STATUS_ON_ICC_SENT";
                SmsManager smsManager = SmsManager.getDefault();
                PendingIntent pi = PendingIntent.getBroadcast(this, 0, new Intent(sent), 0);
                smsManager.sendTextMessage(OpsPhoneNumber, null, DescribeText, pi,null);

                //send email
                i.putExtra(Intent.EXTRA_SUBJECT, "Emergency Location");
                i.putExtra(Intent.EXTRA_TEXT,Html.fromHtml(DescribeText));
                try {
                    startActivity(Intent.createChooser(i, "Send mail..."));
                } catch (android.content.ActivityNotFoundException ex) {
                    Toast.makeText(getApplicationContext(), "There are no email clients installed.", Toast.LENGTH_LONG).show();
                }

             Log.d(TAG, "gps =" + statusOfGPS);
            }
}

//发送短信的第一行

我用


  SmsManager.getDefault（）。sendTextMessage（OpsPhoneNumber，null，
  DescribeText，null，null）；


在清单文件中，我有：

<uses-permission android:name="android.permission.SEND_SMS"/>

我要测试的设备是android 4.2.2和4.1.1
但是应用程序不发送短信如何解决此问题？

最佳答案

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("", null, "< message body>", null, null);

SmsManager需要您的Android mainfest中的SMS_SEND权限。
