Android problem extending QCARPlayerActivity

January 30, 2013 - 7:55am #1

Hello everybody,

I'm trying to extend a Unity Android Activity and adding custom views in Eclipse. I've followed this guide https://developer.vuforia.com/resources/dev-guide/extending-unity-android-activity-and-adding-custom-views-eclipse.

 

On Unity I can generate the .APK with my own 3d model and it run perfectly in my Android device. Then, after build tha Android library based on /StartingArea folder from Unity project and build an Android project to call this library as the guide says, Elcipse show me the next errors at Run time::

Hi, sorry that it does not work for you;

normally you have to pay attention to execute all the steps in that article very precisely and in the exact same order in which they are mentioned;

the procedure is not complex but even a little difference in the execution (e.g. copying a directory rather than moving it, or any other little difference in the AndroidManifest.xml) can lead to a failure in Eclipse;

have a look at this thread:

https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/need-help-including-unity-project-library-eclipse

Here we discussed the same topic...

Hi, thanks for the screenshot; the list of JAR files that you have got there is a bit different from what I get in my Eclipse project;

however that screenshot is illuminating, as it shows that in your case you probably need to also tick (check) the last 3 items in the list (i.e. QCAR.jar, qcarplayerproxyactivity.jar and QCARUnityPlayer.jar);

hopefully that should fix it.

Hi again, and thanks for the reply,

I have checked the three items at Java Build Path (Order and Export section) as you recommend, but I obtain the same result.

You can see my JavaBuildPath estructure in the next image capture::

One more thing, I'm running the project directly into my Android device, and I'm not generating the APK file, should I do?

thanks.,!!!

Hi, the issue is almost certainly due to the fact that you need to export some jars with your APK;

to fix this, go to project Properties, select Jaba Build Path -> select Order and Export tab -> check (tick) the "Android X.Y", "Android Dependencies" and "classes.jar";

build and run again; it should be OK then.
