I'm new at Android world. Just learning. I want to study build this project. But it fails for all R.* members and so other reasons. After searching the web I found several blogs to fix generated R.java files. But I couldn't fix it. Maybe I don't much about Android and Java. Can anybody make a Eclipse project out of this example which is build properly? Thanks in advance!
Try cleaning your project. If that won't work check your xml files for any error. That's the most common reason for getting errors related to R.java*.

I am attempting to create a JAR from IntelliJ using the build artifacts but when I do it is saying
Error: Invalid or corrupt jarfile
Im not sure what im doing wrong though?
Hard to tell from what you have posted. Intellij can be finicky at times especially with the Artifact jar build interface. There is a good tutorial on IntelliJ's website on how to set up the artifact. One area that may provide difficulty is pointing to the Main Class.
An issue I had in building a jar using the tool was selecting the Main Class. Ultimately I typed it in and it worked. Not sure if this is the advice that will solve your problem.
From the intellij website at: https://www.jetbrains.com/help/idea/creating-and-running-your-first-java-application.html
Note the image below.
Other potential issues could be that a dependency was corrupted, although doubtful.
Could also be the Manifest file is referencing a file that is causing the issue. Most Manifest files should be fairly simple and point to the main class. Last but not least email IntelliJ. They are good at responding and if the problem is one that intellij can solve, they will help. Unfortunately they only respond by email and sometimes can take up to a day.
I understand what this error is 'java.lang.NoClassDefFoundError', and why it is caused. My issue is that I don't know how to solve it.
I am attempting to use an external utility library I made for creating inventories in a plugin of mine, and I compiled that library jar in with the plugin I was creating, and upon start up it gave me that error. Any ideas on how to solve this?
I figured that if I compiled the library with my .jar, it should load first to solve this issue...?
If you are using an external library you will need to shade the dependency into your plugin. Or if it is another plugin, ensure your plugin depends and loads after.

I also highly recommend you ask for help on SpigotMC.org or Bukkit.org. There are thousands of Bukkit-Specific plugin developers on there willing to help.
I'm trying to deploy my project but I am facing some problems. When I try to build the APK on Android Studio I get this error:
Honestly I never had contact with .gwt files before and I don´t know what they are. I searched on google about gwt but I did not understand very well what I read.
Here is my project hierarchy:
I remember that I had this file before but I think I deleted it by mistake. I also think this file was generated by LibGDX setup.
Anyway, my question is, how can I solve this problem or how can I make my own gwt.xml file for this project and why is it needed?
Thanks.
[ERROR] Unable to find 'aurelienribon/tweenengine.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
i followed every step in the libgdx wiki on how to install universal tween engine and it keeps giving me this error.
I have no idea what this aurelienribon.tweenengine.gwt.xml is since i cannot find it anywhere on my pc and i dont understand what i can do to fix it.
this is the guide i followed:
https://github.com/libgdx/libgdx/wiki/Universal-Tween-Engine
and i saw someone with the same problem on here who apparently fixed it but i could not deduct how exactly he did it from the details he gave.
thanks in advance.
Reason why it wasnt working was because i only had the tween-engine-api.jar in the libs folder created in the guide at:
https://github.com/libgdx/libgdx/wiki/Universal-Tween-Engine
it in fact needed to have the source jar as well which i did not have because i rarely use them. Turns out gwt needs them in order to compile.
so just to clarify, libs folder must have both tween-engine.api.jar and tween-engine-api-source.jar.
I am trying to connect to Facebook (and eventually Facebook places). I am using the Facebook-android-sdk in Eclipse but I seem to be getting an error message in the graphical view on my main.xml class. the error message is:
the following classes could not be found: com.codecarpet.fbconnect.FBLoginButton
I have imported the FBLoginButton as a referenced library but Eclipse still can't manage to locate this class.
There are no errors in my project and all the correct jars and libraries have been imported.
Anyone got any idea?
It might just be a Eclipse problem and not anything with your code. Try going to "Project" menu -> "Clean" on eclipse which might help in this case. Good luck :)
