Vitamio Sample Error - java.lang.UnsatisfiedLinkError: Couldn't load vinit findLibrary returned null

问题

I'm having trouble running the vitamio-sample from https://github.com/yixia/VitamioBundle.

I am building it with Android Studio and it compiles fine and runs, but when it gets to this line:

if (!io.vov.vitamio.LibsChecker.checkVitamioLibs(this))
    return;

It throws an exception when I run it on my Nexus 5 (and also on a Galaxy S4):

The exception also happens when I'm running the v4.2.0 tree in my own app.

Any idea what I'm missing? In my own app I pulled the vitamio project into a libraries folder and am referencing it like this:

     compile(project(':libraries:vitamio'))

The sample project is left as-is.

回答1:

I am not sure if there is a cleaner way in the newer version of Vitamino (or gradle). But here is how I got it to work with gradle build tools 0.6.

Added a project to my /libraries directory with the vitamino source/sdk. This has a /libs/armeabi /libs/armeabi-v7a with libvinit.so inside.

In my build.gradle for my main project, reference the library project like:

dependencies {

    // other dependencies 

    compile(project(':libraries:vitamio'))

}

Add the following to the bottom of my build.gradle

task copyNativeLibs(type: Copy) {
    from(new File(project(':libraries:vitamio').getProjectDir(), 'libs')) { include '**/*.so' }
into new File(buildDir, 'native-libs')
}

tasks.withType(JavaCompile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
    pkgTask.jniDir new File(buildDir, 'native-libs')
}

Then when i run a clean and rebuild it will copy the native libs to the proper spot and include them in the build.
