# Problem building osrf_rosandroid: missing robotapp files [closed]

This post is a wiki. Anyone with karma >75 is welcome to improve it.

I've been going through this tutorial on how to build a rosjava/rosandroid environment (wiki.ros.org/sig/Rosjava/Android Development Environment) and I'm currently trying to build the sample programs for this tutorial. Though I've been having problems compiling the rosjava due to some compatibility issues, I've been able to work around the kinks.

Currently,I'm having a problem building the osrf_rosandroid sample applications that are found in the package. When I run the command ./gradlew debug in the osrf_rosandoird folder, the compiler displays a lot of missing symbols errors all from the same file. Here is what the compiler is printing out.

[javac] /home/rommel/catkin_ws/src/wksp/osrf_rosandroid/android_app_chooser/src/org/ros/android/android_app_chooser/MasterItem.java:59: package ControlChecker does not exist
[javac]                                    ControlChecker.FailureHandler {
[javac]                                                  ^
[javac] /home/rommel/catkin_ws/src/wksp/osrf_rosandroid/android_app_chooser/src/org/ros/android/android_app_chooser/RobotMasterChooser.java:77: package org.ros.android.robotapp does not exist
[javac] import org.ros.android.robotapp.RobotDescription;
[javac]                                ^
[javac] /home/rommel/catkin_ws/src/wksp/osrf_rosandroid/android_app_chooser/src/org/ros/android/android_app_chooser/RobotMasterChooser.java:78: package org.ros.android.robotapp does not exist
[javac] import org.ros.android.robotapp.RobotId;


There are obviously many more but for the sake of space, I won't write them out.I know what the problem is, it can't find the robotapp folder that has the necessary files. All I need are those files but I have no idea how or where to get them. Any advice given will be greatly appreciated.

Thanks all.
