how to stop ringtone in qt android

gotronics

please may you assist me i need to stop the ringtone after 2 seconds but the function to do so does not work and i have discovered that its all the public methods not working

i am using qt 5.11.1
(SDK Version: 26.1.1, NDK Version: 10.4.0)
jdk1.8.0_181

QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
    if ( activity.isValid() )
    {
        jint notifcationType = QAndroidJniObject::getStaticField<jint>("android/media/RingtoneManager", "TYPE_RINGTONE");
        QAndroidJniObject notification = QAndroidJniObject::callStaticObjectMethod("android/media/RingtoneManager", "getDefaultUri", "(I)Landroid/net/Uri;", notifcationType);
        if ( notification.isValid() )
        {
            // Note that package and class names needs to be separated with '/' and not '.'
            
            QAndroidJniObject ring = QAndroidJniObject::callStaticObjectMethod("android/media/RingtoneManager",
                                                                               "getRingtone",
                                                                               "(Landroid/content/Context;Landroid/net/Uri;)Landroid/media/Ringtone;",
                                                                               activity.object<jobject>(),
                                                                               notification.object<jobject>());
            if ( ring.isValid() )
            {
                QString str;
                ring.callMethod<void>("setStopPreviousRingtone", "(Z)V", true);
                ring.callMethod<void>("play");
                QThread::msleep(2000);
                QMessageBox::information(this, "", str.setNum(ring.callMethod<jfloat>("android/media/Ringtone","getVolume", "()F")));
                if(ring.callMethod<jboolean>("android/media/Ringtone","isPlaying", "(Z)V")){
                    QMessageBox::information(this, "", "playing");
                }
                else {
                    QMessageBox::information(this, "", " not playing");
                }
                
                
                QThread::msleep(2000);
                ring.callMethod<void>("stopPreviousRingtone");
                //ring.callObjectMethod("android/media/Ringtone","setVolume", "(F)V", 0);
            }
        }
    }
}

@gotronics
at what point does your code exactly fail?
here if ( ring.isValid() )?

Also note that many methods require to be called from Android's UI thread (which Qt code doesn't by default!).
For this you can use QtAndroid::runOnAndroidThreadSync()

But also its very likely that the console output (or LogCat) already gives some clues what is going wrong your case.

@gotronics said in how to stop ringtone in qt android:

ring.callMethod<void>("stopPreviousRingtone");
//ring.callObjectMethod("android/media/Ringtone","setVolume", "(F)V", 0);

if(ring. is valid) is ok because it rings or the phone rings very well

the problem is to stop it after 2 seconds by the
the following functions are not working

ring.callMethod<void>("stopPreviousRingtone");

ring.callMethod<void>("setStopPreviousRingtone", "(Z)V", true);

ring.callMethod<jboolean>("android/media/Ringtone","isPlaying", "(Z)V")

sorry if you check again my code i corrected were i had initially commented
ring.callMethod<void>("play");

raven-worx

@gotronics
the JNI signature for your isPlaying call is wrong. Should rather be ()Z (not (Z)V)

Beside that i do not see the methods setStopPreviousRingtone and stopPreviousRingtone in the Ringtone class

gotronics

@raven-worx
setStopPreviousRingtone and stopPreviousRingtone are from RingToneManager
so used incorrectly in RingTone class. I have corrected there and i can now stop the ringtone using this ring.call("stop", "()V");
and ring.callMethod<jboolean>("isPlaying", "()Z")) now working
thank you very much.

i still have challenge on the following

QString str;
  QMessageBox::information(this, " Volume", str.setNum(ring.callMethod<jfloat>("getVolume", "()F")));

i am getting 0 even though the ringtone volume is way above 0 level
