How to send SMS in android?

Hi!
How to send SMS in android?

[SGaist]

Hi,

Did you try to look up the Android API ? A quick search turns out SmsManager.

[Mikeeeeee]

How in Qt to connect to the Android API and use some function, for example createAppSpecificSmsToken (PendingIntent intent)?

[kuzulis]

Use Qt Android Extras helpers. Also you can read about here (from first to last episode).

@Mikeeeeee , you can write a java class which contains the function to send the sms, and after that you can use the QtAndroid and QAndroidJniEnvironment in your cpp class and call the function defined in your java class.
Something like this:-

QtAndroid::androidActivity().callMethod<void>("sendSMS");

I had used "textLocal" (sms platform) in a project i was working on and it worked really nice, so they have few API's which you can make use of.If you want the code for that please have a look at this[http://api.textlocal.in/docs/sendsms].

For more information about QtAndroid[https://doc.qt.io/qt-5/qtandroid.html] and QAndroidJniEnvironment[https://doc.qt.io/qt-5/qandroidjnienvironment.html]

If I add QT + = androidextras, I get an error: Unknown module (s) in QT: androidextras

[Shrinidhi Upadhyaya]

Hi @Mikeeeeee , you need to add like this:-

android: QT += androidextras

[Mikeeeeee]

In .pro the file was compiled. If I add #include <Qt Android Extras> I get errors: 'QtAndroidExtras' file not found , QtAndroidExtras: No such file or directory
#include <QtAndroidExtras>

[SGaist]

Might be a silly question but are you building that with your Qt Android kit ?

[Mikeeeeee]

MinGW does not compile, Clang compiles. Thanks.

[SGaist]

That has nothing to do with your error. You were using a Qt build that was not for Android, likely your desktop build.

MinGW is unrelated to the Qt Android version. The compiler is provided by the Android NDK.

How to call a method in Qt from java SmsManager::createAppSpecificSmsTokenWithPackageinfo(String prefixes, PendingIntent intent)

[jsulm]

@Mikeeeeee Take a look at https://doc.qt.io/qt-5/qandroidjniobject.html

[Mikeeeeee]

Will this option work, or should we do it differently?

    QAndroidJniObject testSms;
    testSms.callMethod< jint > ("createAppSpecificSmsTokenWithPackageInfo(32133)");

Have you already tried? Trial and error is a way to learn...

[Mikeeeeee]

It doesn't work. How can this be fixed to work?

[JonB]

@Mikeeeeee

    QAndroidJniObject testSms;
    testSms.callMethod< jint > ("createAppSpecificSmsTokenWithPackageInfo(32133)");

With the warning that I know absolutely nothing about this:

You are using the overload https://doc.qt.io/qt-5/qandroidjniobject.html#callMethod, callMethod(const char *methodName). It may well be that methodName has to be a method name, "createAppSpecificSmsTokenWithPackageInfo(32133)" is a full function call. You may have to use overload https://doc.qt.io/qt-5/qandroidjniobject.html#callMethod-1, callMethod(const char *methodName, const char *sig, ...), and specify the function signature and pass 32133 as parameter, in order to call functions with parameters?

Have you/can you test if you can call a method which does not take any parameters, does that work OK?

[Mikeeeeee]

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

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