Module "QtMobility.gallery" is not installed

[JKSH]

Hi, and welcome!

@qAminzzz said in Module "QtMobility.gallery" is not installed:

i want to use QtMobility.gallery to find all videos in android device

Qt Mobility was designed for Nokia's old phone platforms (S60, Symbian, Maemo, Harmattan, MeeGo). It never supported Android.

See https://doc.qt.io/qt-5/android.html for Android support.

@jsulm oh, i did not know this, thank you

@JKSH thanks (:

i runned qt in android. now i just wanna get all videos in android device to make an application. something like gallery.
i hope to do this with qt code. but i think there is a java code
please help me to do this with qt

[jsulm]

@qAminzzz Use https://doc.qt.io/qt-5/qstandardpaths.html to get the paths to video/image locations.
Don't forget to request access rights from Android.

@jsulm thanks for link.
i searched in this link and i made this code :

QStringList movies = QStandardPaths::standardLocations(QStandardPaths::PicturesLocation);

    

    foreach(QString file, movies)

    {

        qInfo() << "path: " << file;

    }

output:

path:  "/storage/emulated/0/Pictures"
path:  "/storage/emulated/0/Android/data/org.qtproject.example.videoTesting/files/Pictures"

i think it did not work correctly because in "/storage/emulated/0/Pictures" directory there is no all my android device pictures

please help me

@qAminzzz Where do you store the pictures on your device? Do you store them on sd card?

[qAminzzz]

@jsulm no only on internal storage. i just wanna get all files address that are in my gallery device

[jsulm]

@qAminzzz Does your app request access to images storage?

[qAminzzz]

@jsulm i just did it

QtAndroid::PermissionResultMap resultHash = QtAndroid::requestPermissionsSync(QStringList(
                                                                                  {
                                                                                      "android.permission.WRITE_EXTERNAL_STORAGE",
                                                                                      "android.permission.READ_EXTERNAL_STORAGE"
                                                                                  }
                                                                                  ));

and works fine
should i request permission more?

@qAminzzz
i can show video in my app with these codes

    Video
    {
        id: video
        anchors.fill: parent
        source: "file:///storage/emulated/0/download/video.mp4"
        visible: true
        volume: 20


        MouseArea
        {
            anchors.fill: parent
            onClicked:
            {
                video.play()
            }
        }

and this works fine.
now i want create a class and get all videos in android device with a function and return them to Video.source

Then you can go through all the paths where the user can store something (not only images/videos locations) and then use https://doc.qt.io/qt-5/qdir.html#entryList-1 for each of these paths to get the files there and filter those by file extension.

[qAminzzz]

@jsulm this link shows to get all files in a directory
but might be there a directory in that directory
or might be there 10 directory in one directory and we can't search all them

but in device gallery there is all media like screen shots, apps, downloads and ...
but in this way we can just see all files in a directory not in device
is there any way to do gallery device work?

[jsulm]

You can also use https://doc.qt.io/qt-5/qdiriterator.html which is reqursive

[qAminzzz]

no which does not my request ):, may i have to use java ):
thank you for help (:

Not sure what this means?

"but in device gallery there is all media like screen shots, apps, downloads and" - because the gallery app collects the files from many different locations on the device...
I don't know whether there is an Java API on Android for that.

[qAminzzz]

@jsulm yeah gallery does it. how can i do this me too?
can i search all directories with QDiriterator ?

im new in qt (just 4 month). i know what you feel -
thank you for help

[jsulm]

@qAminzzz said in Module "QtMobility.gallery" is not installed:

can i search all directories with QDiriterator ?

yes, at least those where your app has read access

[qAminzzz]

@jsulm thank you so much
it worked with these code:

function:

void searchPaths(QVariant path)
{
    QStringList files; // add files to this ( paths )
    QStringList filter; // mp4 files filter

    filter << "*.mp4"; // add filter

    qInfo("-----");

    QDirIterator dir(path.toString(), filter, QDir::Files, QDirIterator::Subdirectories); // get all files in directory
    while (dir.hasNext())
    {
        qInfo() << dir.next();
        files << dir.next(); // 
    }
}

use:

searchPaths("enter path here") 

now i can sleep easy. thanks
