how to add import qml module to deploy

[qtnext]

Hi,

my apps use custom components module (a fully qml and javascript
package). I have on Windows this package distribute in the root folder
of my apps (appfolder\Qt\labs\components\custom\..)
I don't know how to add this folder in the package to deploy to device :
I have tryed INSTALLS+ ,deployments, ... but nothing works

The (only?) way to go is to package your qml/js into a resource file.
You can then access them via a "qrc:/" url.

the probiem is that is a qml module (qmldir +js + qml .. no C++) and I
call it in my application in several folders level with import
Qt.labs.components.custom 1.0 . regarding qt lists it seems it's not
possible to embed qml module in qrc.
If there is no automatic deployement method, is there a way to manually
copy files in the folder tree use to create the apk ?

I have tryed to embed qml module in ressource but it don't works (tryed on windows to test).
It seems that in alpha 3 there is  "seamless assets support" : is it what I need to do ? how can I add module in assets if it's that ?

best regards,

import 'qrc:/Qt/labs/components/custom' works ... but it's not the best, i need to embed in qrc the qml module.

Yes, this is what you need, check [1], or even better create a new qml
application and check the source code to see how it works.

Hi,

Could it be that there is an issue loading QML C++ plugins from assets?

 I get:

Yes, I already read this. Loading of .qml, .js and images works fine. Only the c++ .so plugin does not load.

I think this is specific to executables in assets. The .so file is actually found (It's another message if it is not), the logcat says it cannot be "loaded", which I understand as "cannot be executed".

Hi guys.

My first post, hope will be helpful

@Koying
Running ./arm-linux-androideabi-readelf -d ~/Qt/Android/AxA/AxA/qml/
plugins/libandroidplugin_1_1.so
I find the next dependency structure:
0x00000001 (NEEDED) Shared library:
[libQtDeclarative.so]
0x00000001 (NEEDED) Shared library:
[libQtScript.so]
0x00000001 (NEEDED) Shared library: [libQtSql.so]
0x00000001 (NEEDED) Shared library:
[libQtXmlPatterns.so]
0x00000001 (NEEDED) Shared library: [libQtSvg.so]
0x00000001 (NEEDED) Shared library: [libQtGui.so]
0x00000001 (NEEDED) Shared library:
[libQtNetwork.so]
0x00000001 (NEEDED) Shared library:
[libQtCore.so]
0x00000001 (NEEDED) Shared library:
[libQtSystemInfo.so]

After you will check all those libraries as required and make a clean/
build, the libraries will must work.

Ups, ignore the post date :)

Just figured out, that a subfolder, which you may import, must be written with capital:

import 'subfolder" --> ERROR
import 'Subfolder' --> OK

and when the 'Subfolder' is in the 'projectName/qml/Subfolder/' path, it gets copied automatically to the device! (because it is added do DEPLOYMENTFOLDERS in the .pro)
