Up front, I\'ll say that I\'ve already solved this, in my own way, but I feel something in the Android bu

Answer 1

None of the previous answers solved my problem, but this did: All along the problem was that a necessary subdirectory and file were not present. All I had in my libs folder was an armeabi folder containing the proper .so file, but there are supposed to be 3 others, each with a .so file in them. Not certain yet which of the other three (armeabi-v7a, mips, or x86) was the required one, but I do know that all three were automatically generated when I added the Application.mk file to the same folder as the Android.mk file, and made sure it had the following line in it:

APP_ABI := all

For me, that line is the only text in there. When ndk-build is then run the Application.mk file apparently causes "all" the 4 folders to be created and the proper .so files to be created in them. Once I got Application.mk in place, I ran ndk-build again, and then did a clean and a clear on my Eclipse project before trying again. Everything ran perfectly.
