Hi:

    I had some problems when I use the qt for playbook SDK.

    1.The applications that developed by qr creator is very very big.

        The helloworld example is also 80.2M,

        Why? I don't know that , I'm so confused.

    2.How can I get the *.bar after I finished the application?

Who could tell me? Thanks a lot.

probably because you've included all possible Qt libraries, try to compile with only ones that you really need. For example if you don't use networking there is no reason to include QtNetwork library

>2.How can I get the *.bar after I finished the application?

Just deploy your app to sim/plabook and .bar file will be created for you.

thanks very much, let me have a try .

I‘m still confused , I haven't included the unuseful libraries , and I checked the application again and again, it also so big. Oh my god.

Are you building a debug load?  If you are including all debug symbols, I expect it will be much larger than a stripped variant.

Inside your project make new folder called "lib"

Inside that folder put libraries you use , in my Qt Quick projects there are: libQtCore.so.4,libQtDeclarative.so.4,libQtGui.so.4, libQtNetwork.so.4,libQtOpenGL.so.4,libQtScript.so.4,

libQtSql.so.4,libQtSvg.so.4,libQtXml.so.4,libQtXmlPatterns.so.4

In your bar-descriptor.xml file replace this line: 

<assetpath="%QT_INSTALL_LIBS%">lib</asset>

with

<assetpath="lib">lib</asset>

 Now, your .bar file should be around 13MB which is Ok. Of course, put only libraries which you use inside "lib" folder.

I think your answer is great.

but I still have some problem.

1. I can't find where to make a new floder, I clicked the rightmouse, it had no.

2.So I make a floder called mylib in C:\ and replace the line with 

<assetpath="lib">lib</asset>

    and it can build.but when I deploy it, it said that:

java.lang.NullPointerException

Could you tell my why please? thanks.

Make folder "lib" inside your project folder manually, with windows explorer.

You get that error, because your syntax is wrong, line startswith <assetpath.... and ends with <\asset> , thats no valid xml. Over there my syntax is wrong also, space get eaten when i copied. It should be 

<asset path="lib">lib</asset>

This will work.
