[PROBLEM RESOLVED, see at the very bottom]

Hey guys!

I am trying to import into Eclipse an Android project which contains native code.
The application was created and developed using the following Eclipse tools:
• Eclipse version : Juno Classic 4.2.0
• Android ADT version : 20.0.3
• Additionnal plugins : CDT v8.1.0

On my side i am using later versions:
• Eclipse version : Juno 4.2.1
• Android ADT version : 22.3.0
• CDT Version: 8.1.2.201302132326

The source code compiles into binaries outside eclipse without any problem. However, when I import the source code into Eclipse as an Android application, the project folder behaves weirdly. It does not even open. Nomatter what i do with the folder (select, right click, etc), the exception appears in the error log (see below, also see screenshot in attachements).

When I import the project for the first time, I get an error message: serializing CDT project settings >>> nullpointer exception. Also C/C++ indexing fails with NPE exception.

The problem is obviously related to the CDT plugin and .cproject file (see attachements). Any ideas, what might be the concrete reason and how can I fix the issue?

Thank you in advance.

Veronika

[SOLUTION]

I have resolved the issue by manually replacing CDT plugin with the v8.1.0 version. The project now opens fine.
This obviously means that there are incompatibilities between v8.1.0 and 8.1.2 versions.
