failed to load images

literA2

Hi,

I am trying to deploy my app into mobile device however the images cannot be loaded because I didn't include them in resource file.

Please advise where should I put the images, i did these while running only on desktop:

@
QDir d;
view.rootContext()->setContextProperty("imagePath", "file:///" + d.absolutePath + "/images/xhdpi/");
@

Hi,

You have to embed the files in your package. For example, on Android you can use what they call Assets

Hope it helps

@SGaist thanks for the reply.

That is what i am thinking also because based on the error message it can't find the images into file file://data/data/xxx/files/assets location.

Should this be different in ios, i guess.

Can you please advise how to do it? Thanks

SGaist

You should rather use QStandardPaths to retrieve the correct path to your files. file://data is not valid at all in the mobile world.

@SGaist can you please provide an example on how to use QStandardPaths ?

And also how to embed the images into the package. Thanks

My bad, you don't need QStandardPaths to access the resources. You can use:

QCoreApplication::applicationDirPath() + QLatin1String("/../Resources/") + your_resource_path

@SGaist Thanks for the reply.

However, I managed to resolved the issue on Android by these steps:

added "ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android" in .pro file
under android folder, i created assets folder and placed the images there
then used "assets:/filename.png" to get the images.

I am having problem now in ios. I tried creating assets catalog based from the link you provided, however i'm having problem how to call the images or path to use.

@
ios {
assets_catalogs.files = $$files($$PWD/*.xcassets)
QMAKE_BUNDLE_DATA += assets_catalogs
}
@

i tried this also:

@
ios {
imageResource.files =images/*.png
QMAKE_BUNDLE_DATA += imageResource
}
@

it is trying to find the images from qrc:/qml/ directory however, i didn't include the images into resource file. Once i open the app package, images folder is located on main directory.

The path to the iOS assets is QCoreApplication::applicationPath() + QLatin1String("/../Resources/") + path_to_your_file;
