How to save files under Android/data?

[Bremenpl]

Hello there,
I am developing an Android application using Qt 5.13.0. Using the https://doc.qt.io/qt-5.9/qstandardpaths.html I am tryng to figure out which path will lead me to the Android/data directory:

I have set the package name in the android manifest file to com.company.appname.
I would appreciate all help.

Hi @bremenpl

Can you please check QStandardPaths & enum QStandardPaths::StandardLocation.

namespace {

void createAppFolder(const QString &folder)
{
    QDir dir(folder);
    dir.mkpath(".");
}
}


QString defaultFolderPath()
{
    const QString path = QStandardPaths::writableLocation(QStandardPaths::AppDataLocation);
    if (!QFileInfo::exists(path))
        createAppFolder(path); 
    return path;
}

All the best.

@pradeep-p-n Hi, thanks for answer,
I have already tried QStandardPaths::AppDataLocation enum value. It places the file in a location that is not accessible to the user (/data). Instead, I am looking for an enum that would access /storage/emulated/0/Android/data, since this path is accessible "outside" the application.

With these piece of code I have checked all the available locations:

qDebug() << "Config path set to:" << configPath;
for (int i = 0; i <= static_cast<int>(QStandardPaths::AppConfigLocation); i++)
{
	const QString tmp = QStandardPaths::writableLocation(static_cast<QStandardPaths::StandardLocation>(i));
	qDebug() << "Path" << i << tmp;
}

Seems like Qt cannot save the file where I need to:

Path 0 "/data/user/0/org.qtproject.example.mri/files"
Path 1 "/storage/emulated/0/Documents"
Path 2 ""
Path 3 ""
Path 4 "/storage/emulated/0/Music"
Path 5 "/storage/emulated/0/Movies"
Path 6 "/storage/emulated/0/Pictures"
Path 7 "/data/user/0/org.qtproject.example.mri/cache"
Path 8 "/data/user/0/org.qtproject.example.mri/files"
Path 9 "/data/user/0/org.qtproject.example.mri/files"
Path 10 "/data/user/0/org.qtproject.example.mri/cache"
Path 11 "/storage/emulated/0"
Path 12 "/data/user/0/org.qtproject.example.mri/cache"
Path 13 "/data/user/0/org.qtproject.example.mri/files/settings"
Path 14 "/storage/emulated/0/Download"
Path 15 "/data/user/0/org.qtproject.example.mri/cache"
Path 16 "/data/user/0/org.qtproject.example.mri/files/settings"
Path 17 "/data/user/0/org.qtproject.example.mri/files"
Path 18 "/data/user/0/org.qtproject.example.mri/files/settings"

Any ideas?
