    <p>I've made an android library project that uses some native libraries.</p> <p>I've made the jni wrapper and put the native libs (.so) in the libs// folders. The native libs are compiled using cmake, for armeabi, armeabi-v7a, x86 and mips.</p> <p>I export this project to a jar and put this jar into a "normal" android project. I then export this project to an apk and can see that my libs are bundles into it.</p> <p>However, when i install the apk, the libs corresponding to the device are not copied into /data/data/com.my.app/lib and obviously, running the app complains about not finding the libs (UnsatisfiedLinkError).</p> <p>I've search through SO and everywhere i can but found no answer that solved my case.</p> <p>i'm using Eclipse, btw</p> <p>Thanks for your help</p> <p><strong>UPDATE</strong></p> <p>OK, i've read the doc in the ndk and seen the examples, and unfortunately, i can't see the solution.</p> <p>The ndk build the c code into shared libs and places them into the appropriated location in the project. But it doesn't generate anything that says that the libs must be installed with the apk.</p> <p>My goal is to provide an android library (so a jar), that can be included within an android application. I don't see the real difference between what i'm doing (compile the c libs using cmake and package the jni and java compiled classes into a jar) and what is done with android.mk</p> <p>If you see what i'm missing, feel free to tell me (even if its obvious).</p> <p>thanks</p> <p><strong>UPDATE</strong></p> <p>i've made a dirty hack: in the libs folder of my application, i've put the jar file containing my classes and my native libs and a copy of the .so files for each arch. Suprise, the libs are no installed in /data/data/com.me.myapp/lib</p> <p>It seems to confirm that it's a packaging problem.</p>

    3. COYou can't just place the library in the NDK project, you have to include it in the Android.mk file - there is plenty of documentation on this as well as examples here on SO
