creating my first android app : DefaultNodeFactory symbol not found. [closed]

Hi, I followed the steps in http://ros.org/wiki/ApplicationsPlatform/Clients/Android and installed the android developer tools as explained in here. I Also followed step 4 in creating your own android app, but after hitting rosmake --threads=1 i get the following error on 62nd package make which is my project package that DefaultNodeFactory is not being find. I have copied the error part of the make down below. Also if I do rosmake on any of the tutorial packages they get to compile fine but when I used the steps explained on the website i keep getting this error, so if someone could help me I would really appreciate it.

Maybe you use old version rosjava. I don't see class DefaultNodeFactory in my project. Try compare source from your project with source from my project.

This could be caused by having an older version of Rosjava. With the latest version of Rosjava, DefaultNodeFactory can no longer be called with no arguments. RosActivity.java in the appmanandroid library was updated to reflect that. The line where you're getting the error is one that changed.

I would try updating your version of rosjava. Try:

hg pull
hg update

in rosjava_core. If there are any more difficulties in the process for building Android apps let me know. I'm trying to make the documentation as clear as possible.

Hi thanks for the response. When I updated the my rosjava it seems it updated 5 packages and I started creating a new package again and the problem still exist. I still get the same error on the top. @Alexandr: I checked my source code against yours and it seems that everything is the same but I do not know why it gives me this errors. One more thing that I keep having a problem with is that when I walk through one of the tutorial after creating the package and typing rosrun appmanandroid android_create --create ... I run rosinstall ROS_DIR . in which I keep getting errors each time that ros stack is not found. it asks me to either types it in manually in .rosinstall or install the whole ros stack from website using .rosinstall. I do not know to be honest if this would have any impact on this or not. Can you please tell me the step by step to setup rosjava please. I have been working to try to fix this thing right now for weeks, but no success. thanks, Vahid.

I pushed a change to the appmanandroid library to fix this issue. I did a setup of a whole environment last night and got similar feedback from someone else. We were able to fix this issue on our installations after I updated appmanandroid. So sorry for the issues. Hope it will work now.

I ran into the same issue awhile ago while trying to build the existing android apps. The API (rosjava) has been refactored, but the apps haven't been updated to reflect it yet. I just pulled a pre-refactor version of rosjava, but it sounds like someone else in this thread has committed a more permanent fix.

By applying the patch mentioned on the website it seems I fixed this error, but it seems that another error occurred which is in regards to {build.Target} not being found or something. I wanted to know how should fix this error now. Thanks, Vahid.

I don't think I've seen that error before. Do you think you could post more detail? I'll see if I can replicate it.

selliott ( 2012-02-23 09:58:19 -0500 )edit

Is it possible that you're missing components of the Android SDK? Try running the 'android' command with no arguments. The AVD Manager should come up. Make sure you have all the API levels selected. Remember to check the box for obsolete packages so you can install API 9 if it's missing.

selliott ( 2012-02-23 10:15:03 -0500 )edit

Maybe double check your environment variables too.

selliott ( 2012-02-23 10:16:32 -0500 )edit

I ran the android command and once the window popped up I was able to see almost all of the SDKs to be installed, even those that were obsolete like API9.

vahid ( 2012-02-23 10:22:21 -0500 )edit

What should I check as far as environment variables?

As far as I can see your environment variables look fine. What is the exact error you're getting? Also, you mentioned that you saw all the SDK components. Did they say "Installed" next to them?

selliott ( 2012-02-23 10:32:16 -0500 )edit

yes it said install next to the SDKs only the things like examples and so on were on installed.
