Several (my and third-party) native libraries in Android NDK

I need to use two native libraries: one is mine and the other is third-party. While I used them in separate projects, everything was in order. But now I get Exception Ljava/lang/UnsatisfiedLinkError.

I am using Eclipse.

I found out that if I put the existing library in libs / armeabi, Eclipse will start compiling its own code and it will not work. If I rebuild the JNI part from the command line, compilation will succeed, but the third-party library will disappear. Really stupid.

So, how do I tell Eclipse to use the existing .so library with the library that needs to be built? Libraries are independent.
