some error launch when run the "Demo of Bones-Android-Ninja"

[cefengxu]

Hello:

i have download the Demo( :Bones-Android-Ninja) and the "Bones"，  and then finish the Setup on Eclipse, there are no error of the project now.
However, when i click " Run as -  Android Application ",  some error log will be shown as follow:

[2015-10-19 16:46:23 - Bones-Android-Ninja] Dx
trouble writing output: already prepared
[2015-10-19 16:46:24 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/threed/jpct/Animation;
[2015-10-19 16:46:24 - Bones-Android-Ninja] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/threed/jpct/Animation;

what's wrong with the code or the setup of the project ?
Thanks ~~!!!!

this is caused by your eclipse setup. most possibly jpct.jar exist in 2 different locations. did you try importing Eclipse project that comes wih Bones demo into your workspace? (as opposed to make setup yourself)

Dear raft:
raft , thanks ~~

actually , my project setup as follown:
1- import "Bones-Android-Ninja" into the workspace; ( the log description "Project 'Bones-Android-Ninja' is missing required Java project: 'Bones' " )
2- so import the Bones into the workspace as well ;
3- this time , i do not change anything and run the application ;
the error log was shown (now is different):

mm I dont know actually what is happening there. last time I tried importing the demo ptoject into Eclipse and also imported Bones as you did and it was working okey.

[cefengxu]

it's work ~! deal with as follown:

1- change the name of file of lib : revising from 'lib' to 'libs'
2- change the  build path of the jpct-ae.jar : right click -> Properties -> 'java build path' -> 'libraries' -> 'chage the path for jpct_ae.jar'

summary :  the android just know the 'libs' instead of 'lib' !

Additional Question:
this demo just add a Ninja again and again ??
My Purpose : To run a model with animation basic on android and see how dose the code do
Thx~~~

[raft]

cool, I'm glad you solved it.

you can add and remove ninjas with the buttons on the screen

[cefengxu]

nonono ~ just lots of  ninja stay there~

My purpose is 
" the ninja do some animation on the screen ~~"
"or how to use the sample code in project 'Bones' "


thx again raft ~~~

[raft]

try the menu button

[cefengxu]

thank you so much , raft~
