android.permission.SEND_SMS must be added to .pro file?

No, it must be added into the manifest (AndroidManifest.xml) ==> editing-manifest-files

[Mikeeeeee]

Void MainWindow::sendSMS is missing ")". Added so and still not working. What's right?

void MainWindow::sendSMS(const QString& phoneNumber, const QString& message)
{
    QtAndroid::runOnAndroidThreadSync([phoneNumber, message]  {
        // get the Qt android activity
        QAndroidJniObject activity = QtAndroid::androidActivity();
        if (activity.isValid()){
            // get the default SmsManager
            QAndroidJniObject mySmsManager = QAndroidJniObject::callStaticObjectMethod("android/telephony/SmsManager",
                                                                                       "getDefault",
                                                                                       "()Landroid/telephony/SmsManager;" );
            // get phone number & text from UI and convert to Java String
            QAndroidJniObject myPhoneNumber = QAndroidJniObject::fromString(phoneNumber);
            QAndroidJniObject myTextMessage = QAndroidJniObject::fromString(message);
            QAndroidJniObject scAddress = NULL;
            QAndroidJniObject sentIntent = NULL;
            QAndroidJniObject deliveryIntent = NULL;

            // call the java function:
            // public void SmsManager.sendTextMessage(String destinationAddress,
            //                                        String scAddress, String text,
            //                                        PendingIntent sentIntent, PendingIntent deliveryIntent)
            // see: http://developer.android.com/reference/android/telephony/SmsManager.html

            mySmsManager.callMethod<void>("sendTextMessage",
                                          "(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Landroid/app/PendingIntent;Landroid/app/PendingIntent;)V",
                                           myPhoneNumber.object<jstring>(),
                                           scAddress.object<jstring>(),
                                           myTextMessage.object<jstring>(), NULL, NULL );

              }
        else {
            qDebug() << "Something wrong with Qt activity...";
        }
    });
}

@Mikeeeeee What do you mean with "not working"? Do you have an error message? Is there an application crash?

Just say "not working" does not give any information to help you!

PS: Sorry for the missed parenthese

[Mikeeeeee]

Error: "org.qtproject.example" crashed.

Error: "org.qtproject.example" crashed.

That's also not helpful, we can not see what you are doing, if you want help, than you must explain what is the problem and what is your development environment/settings:

• which Qt Kit are you using to build your project? (for example Android for armeabi-v7a (Clang Qt 5.7.1 for Android armv7)
• which Qt Creator Version you are using
• what is your target device? It is a smartphone, a tablet or an emulator?
• what Android version are you targeting?
• when does the application crash? When you starting the application or when you try to send a SMS?

You give nothing to enable us to help you, this is all up to you.

Last, but not least, is your device capable to send SMS?

[Mikeeeeee]

1. I use Android for armeabi-v7a (Clang Qt 5.12.3 for Android armv7)
2. I use Qt Creator 5.12.2
3. Target device - smartphone
4. Android version 6
5. Crash application when I start the function of sending SMS
6. My smartphone is able to send SMS

The SmsManager class has a getcarrierconfigvalues() function without an argument.
This code also generates an error:

    QAndroidJniObject testSms;
    testSms.callMethod< jint > ("getCarrierConfigValues()");

Have only just seen this. As I said, and as the documentation states, the argument is supposed (according to my understanding) to be a method name, so getCarrierConfigValues and not getCarrierConfigValues(), or any such with parentheses. I don't know where you are in your investigations, but did you at least try something like that once? If you have gotten further through since then, you may ignore.

[Mikeeeeee]

It's too not work

    QAndroidJniObject testSms;
    testSms.callMethod< jint > ("getCarrierConfigValues");

For those interested, after quite a struggle, I've managed to send SMS on Android using the multi part API.
The C++ code is also notified of the Delivery from the Android BroadcastReceivers \o/

All this is encapsulated in a SmsSender object with an easy API:
Q_INVOKABLE void sendText(const QString &destMobile, const QString &msg);

The code is published on github here: sendSMS.
There is a minimalist QML GUI.

Hope it will save some people some time! ;)
