I'm trying to set up cocos2d-x for android and I followed a video tutorial
I passed the steps for terminal without any problem (setup.py
command result is as expected).
My problem is after I set NDK_ROOT
in C/C++ Build - environment section, I get some java.lang.NullPointerException
exceptions.
For example when I restart eclipse I get the following error.
An internal error occurred during: "Android Library Update".
java.lang.NullPointerException
When I try to reopen C/C++ Build - environment section I get The currently displayed page contains invalid values.
error and I can't edit the environment values.
I checked java build path, there is no JRE system library and when I try to add I get the same error
An error has occurred. See error log for more details.
java.lang.NullPointerException
How can I fix the problem? Thanks for your help.
I'm working on
- Mac OS 10.9.4
- android-ndk-r9d
- apache-ant-1.9.4
- cocos2d-x-3.2
- adt-bundle-mac-x86_64-20140702
I've been trying to fix this for a while, I'd suggest comparing the .cproject
file in your project with the one in templates/cpp-template-default
and removing extra section(s) in your file.
I had to remove one section, I don't why it was added but it works now.
Update: It seems this section is added once you open eclipse with NDK_ROOT not defined, and after that, even if you define it, this section stays there in the configuration files and causes the same errors, you need to remove it to get your project to work.
The section looks like this, you can remove it safely after you close eclipse.
