Qt Android returns Invalid audio format

Question

I have a Qt code with a QSound object that is supposed to read two wav files on a thread.

My code works on iOS simulator, but not on Android.

My thread code that reads wav files :

ClickThread::ClickThread(): highClickFile("://high_click.wav"), lowClickFile("://low_click.wav"), isRunning(false)
{
    this->highClick = new QSound(highClickFile);
    this->lowClick = new QSound(lowClickFile);
    this->setPeriod(120);

}

void ClickThread::process(){
    while(this->isRunning == true)
    {   if(!this->isRunning) break;
        highClick->play();
        QThread::msleep(period);
        highClick->stop();
        if(!this->isRunning) break;
        lowClick->play();
        QThread::msleep(period);
        lowClick->stop();
        if(!this->isRunning) break;
        lowClick->play();
        QThread::msleep(period);
        lowClick->stop();
        if(!this->isRunning) break;
        lowClick->play();
        QThread::msleep(period);
        lowClick->stop();
    }
}

There is the error message I got :

W linker  : Warning: "/data/data/org.qtproject.example.MyProject/qt-reserved-files/plugins/audio/libqtaudio_opensles.so" has unsupported flags DT_FLAGS_1=0x80 (ignoring unsupported flags)

Thanks for your answers

EDIT :

The problem was that my wav file was encoded in 24 bits. Android doesn't seem to use this kind of encoding for PCM files, referring to this website : https://developer.android.com/reference/android/media/AudioFormat we only can have 8, 16 or 32 bits.

So, I used FFmpeg to encode my wav files in 16 bits and now my code works ! Check that link for an exemple of encoding with FFmpeg : ffmpeg FLAC 24 bit 96khz to 16 bit 48khz
