What Android device are you using? Make sure it is one of the supported devices listed on the SDK homepage: https://ar.qualcomm.com/qdevnet/sdk

You should be able to install and run your APK file from Unity, Eclipse isn't needed for Unity development. Simply use the Build & Run option in Unity.

You cannot export Unity content for use with a regular Android project. Unity is a completely self-contained game development tool, and cannot be used to produce content for other development environments.

That's a generic Unity problem, not a QCAR-specific problem. You should be able to place the model in your project's Asset folder (or any subfolder of the Asset folder). As long as it is in one of the formats listed in the Unity documentation, then Unity should recognize it as a model. You can then drag an instance of the model into your scene.

You are still using Unity, correct?

When you create a trackable using the My Trackables system on the website, be sure to download the trackable using the "Unity 3 Android Project" format. Unzip the file that is downloaded to your computer.

In Unity, you should have a project that is already set up with the QCAR extension. To do this, import the QCAR-Beta2.unitypackage or one of the sample packages. Now you can copy the trackable files to the correct folders inside your project:

Assets/Editor/QCAR/ImageTargetTextures
Assets/StreamingAssets/QCAR

That's right, neither the QCAR SDK or Unity can be used to create 3d content.

There are two choices when using the QCAR SDK:

1) Download the QCAR SDK, and use the Android SDK/NDK to write an Android application. You will write your code in Java and C/C++, and will use OpenGL ES to display 3d content. There is no standard importer/renderer for animated 3d models, so you will need to write your own or find a 3rd party library.

2) Download the QCAR Extension for Unity, and use the Unity game development tool to create your application. This is a higher level tool, making it easier to import and render your 3d content, including animated models. It also comes with nice math and physics libraries built in, amongst other things. You write your code in Javascript or C#.

There are guides for using either approach on our website: https://ar.qualcomm.com/qdevnet/

See the "Get Started" section for help with the first option, and the "AR Extension for Unity 3" section for help with the second option.

Thanks, :)
so you mean QCAR SDK and Unity cant make 3d character and animation. don't you?
hmm. so blender can make some animation and character?

I have one more question, I installed qualcomm ar extention unity but i dont know exactly how to use it. if I don't install unity 3d, so i don't use this extention. that's right?
so.. does this extention need to be installed unity 3d?

When you talk about making a 3d image, are you talking about modeling 3d objects like the teapot included in the examples? Or 3d characters with animation? Neither the QCAR SDK or Unity can help with this. Both require that you create your content ahead of time, using other tools. You can use a program like Blender to create a 3d model, then save it in a format that Unity can import. Here's some information on the modeling tools and model formats that Unity supports:
