    <p>I'm a bit confused with what I'm currently attempting: I want to cross-compile a C library for use with Android through the NDK, so that I can create a JNI wrapper and call some of its functions from my Android java code.</p> <ul> <li><p>I followed this guide to crosscompile libopus (the library I want to include in my project): <a href="http://mortoray.com/2012/08/21/android-ndk-cross-compile-setup-libpng-and-freetype/" rel="nofollow">http://mortoray.com/2012/08/21/android-ndk-cross-compile-setup-libpng-and-freetype/</a> which means <strong>I currently have a standalone toolchain at /opt/android-ext/, with a lib folder that contains the library I cross-compiled (libopus.a, libopus.so, etc)</strong>.</p></li> <li><p>I also already have a jni folder on my Android project, which contains some C code with the JNI bindings that I want, and that I can call from my Java code, but it does nothing (I can call it but it's a blank function). This means that in my project, there's a /lib/armeabi directory with "libopusUtilsNative.so" (the wrapper).</p></li> </ul> <p>My question is:</p> <p>How do I add the library that I just crosscompiled to the project, so that (for example) I can just do an #include call on the C source code file that I already have and get access to the library functions? I'm a bit lost with how to:</p> <ol> <li><p>Include the library I cross-compiled into my project.</p></li> <li><p>How to make the wrapper code I created include it (I'm guessing this has something to do with adding some code to my Android.mk file, but I'm clueless).</p></li> </ol>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
