如何将ndk-build用于应用程序库

Question

I had to build a library using ndk-build. Did that. it produced all the libXX.so files. It already had a apk file in the bin dir. Now how does this fit together. Should I be installing all the lib in the lib folder of my android phone and then install the apk and run it . Is this the way?

Answer 1

Do you use a build system? Using Maven I used a local repository and put the .so files there (in appropriately named) directories, and then my build process picked them up when creating the apk. Let me know how you are building your apk and I might be able to help further.

Edited to include some Maven stuff

Dependency on a native library:

<dependency>
    <groupId>android.native</groupId>
    <artifactId>libhello-jni</artifactId>
    <version>0.8</version>
    <classifier>armeabi-v7a</classifier>
    <type>so</type>
</dependency>

Using a local repository (where ${third-party-jars} is a path on your system eg <third-party-jars>/local/path/to/third/party/jars</third-party-jars> :

<repository>
    <id>third.party.closed.source.local.repo</id>
    <name>Third Party Closed Source Local Repository</name>
    <url>file://${third-party-jars}</url>
    <!-- Files must be in groupId/artifactId/version directories and named
         artifactId-version.extension
         Example: ${groupId/$artifactId/$version/$artifactId-$version.$extension -->
</repository>

The Maven build then just picks the so up as a dependency like it would a jar file etc.
