    Description

       Adding

      [...]
QString path = QStandardPaths::writableLocation(QStandardPaths::AppDataLocation);
qDebug() << "QStandardPaths::AppDataLocation is"; 
qDebug() << path;
[...]

      in main() after `QGuiApplication app(argc, argv);` in the "Qt Quick Controls 2 - Gallery" example returns:

      D Gallery : ../gallery/gallery.cpp:67 (int main(int, char**)): QStandardPaths::AppDataLocation is
D Gallery : ../gallery/gallery.cpp:68 (int main(int, char**)): "/"

      when deploying Debug builds for Android .

      In Release builds:

      D Gallery : (null):0 ((null)): QStandardPaths::AppDataLocation is
D Gallery : (null):0 ((null)): "/data/user/0/org.qtproject.example.gallery/files"

      which is correct.

       

      This issue was also present when I built Qt for Android from source at commit 1c1557aa93cd139688ebfe5a9922a60ef2b2d8c6 in qt5.git in the middle of December 2017. Additionally, iOS and OS X Debug builds do not have this issue.
