Fedora 17 Development Setup

Install Eclipse

• Download Eclipse Indigo for Java SE developers.
• Unpack tar into ~/
  • Create shortcut on desktop that points at /home/myuser/eclipse/eclipse
• Install Eclipse Software:
  • Git
  • Subclipse
  • ADT-Plugin (Android)

Download MRL source

Assumes workspace used is "~/workspace"

cd ~/workspace/ &&\
 git svn clone http://myrobotlab.googlecode.com/svn/trunk/ myrobotlab

Setup Git

1. If you haven't set up your global Git email yet, do so by running this with your email address you want to use (best bet is to use whatever email address you plan to use with GitHub):

   git config\
    --global user.email "lowrider@myrobotlab.org"
   

2. Add a .gitconfig file so that you don't have to worry about files you will never want to check in:

   echo ".gitignore
   android/.settings/
   android/bin/
   android/gen/
   mrlclient/bin/
   myrobotlab-tests/bin/
   myrobotlab/bin/
   " > ~/workspace/myrobotlab/.gitignore
   

3. Set up your bash so that it includes the current working Git branch when you're in a folder containing a Git repo by adding this to ~/.bash_profile:

   parse_git_branch() {
   git branch 2> /dev/null\
    | sed -e '/^[^*]/d' -e 's/* \(.*\)/[ \1 ]/'
   }
   PS1="\\w \\[$(tput bold; tput setaf 3)\\]\$(parse_git_branch) \
   \\[$(tput sgr0)\\]\\$ \\[$(tput sgr0)\\]" 

   Gives you:

Import projects

• Open Eclipse
• Start importing:
  • File -> Import...
• Select the Git method:
  • Git -> Projects from Git
• Repository Source: local
• Git Repository:
  • Click the Add... button to the upper-right
  • Browse to the location used above (~/workspace/myrobotlab in my case) and select that folder
  • Click the Finish button
• Wizard for importing:
  • Use the default selected "Import existing projects". This will import all the projects checked out into the local Git repository.

Initial Hicups

1. Error showing up in Eclipse:

   Failed to get the adb version:
    Cannot run program "/home/myuser/android-sdks/platform-tools/adb"
     : error=2,
    No such file or directory from
     '/home/myuser/android-sdks/platform-tools/adb' - exists=true
   

   Run the command in Terminal to test what is wrong:

   ~/android-sdks/platform-tools/adb
   

   Result:

   Error: /home/myuser/android-sdks/platform-tools/adb
     : /lib/ld-linux.so.2
     : bad ELF interpreter
     : No such file or directory
   

   Find a suggestion online and try it

   sudo yum install glibc.i686
   

   Try it again:

   ~/android-sdks/platform-tools/adb
    : error while loading shared libraries
    : libncurses.so.5
    : cannot open shared object file
    : No such file or directory
   ~/android-sdks/platform-tools/aapt
    : error while loading shared libraries
    : libz.so.1
    : cannot open shared object file
    : No such file or directory
   

   Seems like I'm missing some required 32-bit files

   sudo yum install\
    ncurses-libs.i686\
    libstdc++.i686\
    zlib.i686
   

2. Error showing up in Eclipse:

   Android requires compiler compliance level
    5.0 or 6.0. Found '1.7' instead.
    Please use Android Tools > Fix Project Properties.
   

3. android project compiler complaints (317 errors):

   Android cannot be resolved to a type
    AndroidActivity.java
    /android/src/org/myrobotlab/android
    line 30	Java Problem
   

   Possible issue:

   import org.myrobotlab.service.Android;
   

   Changed the following for the linked myrobotlab src folder in the android project. From:

   WORKSPACE_LOC/myrobotlab/src
   

   To:

   WORKSPACE_LOC/myrobotlab/myrobotlab/src
   

4. mrclient project compiler complaints (139 errors):

   CMDLine cannot be resolved to a type
    MRLClient.java
    /mrlclient/src/org/myrobotlab/client
    line 156
    Java Problem
   

   Possible issue: mrclient src folder framework isn't linked properly. From:

   WORKSPACE_LOC/myrobotlab/src
   

   To:

   WORKSPACE_LOC/myrobotlab/myrobotlab/src
   

5. android project compiler complaints (97 errors):

   R cannot be resolved to a variable
    AndroidActivity.java
    /android/src/org/myrobotlab/android
    line 34
    Java Problem
   

   This usually shows up if there are Android config issues. This might be related:

   The method onAccuracyChanged(Sensor, int)
     of type Android must override a superclass method
    Android.java
    /android/myrobotlab/org/myrobotlab/service
    line 101
    Java Problem
   

   Installed JDK 1.6 (simply download the RPM bin, chmod +x, and ./jdk.bin execute it) and restarted eclipse.

6. android project compiler complaints (22 errors):

   The method onAccuracyChanged(Sensor, int)
     of type Android must override a superclass method
    Android.java
    /android/myrobotlab/org/myrobotlab/service
    line 101
    Java Problem
   

   GroG suggests this is because of Android compatibility issues.
   Fix: change project settings to use Java Compiler 1.6 instead of 1.5
