hi there my problem is that i can't build the project correctly in Eclipse.

i've already set the project->properties->C/C++ General->Paths and Symbols to include directory "${NDKROOT}/sources/cxx-stl/gnu-libstdc++/4.6/include" and the NDKROOT is set correctly.

the error says that it has undefined reference to "AndroidBitmap_getInfo".and this is included in the directory above. And I can figure out what's wrong. Could anybody help me with this? The message in the Console is as follows.
