本机库（.so文件）不会添加到Android项目 [英] Native libraries (.so files) are not added to an android project

问题描述

我想使用 sqlitecipher 库要求使用本机库。他们的教程很简单，但它并没有为我工作。每次我收到以下错误：

I'm trying to use sqlitecipher library which requires using native libraries. Their tutorial is very simple but it doesn't work for me. Every time I get the following error:

FATAL EXCEPTION: main
        java.lang.UnsatisfiedLinkError: Couldn't load stlport_shared from loader dalvik.system.PathClassLoader[dexPath=/data/app/org.example.test-2.apk,libraryPath=/data/app-lib/org.example.test-2]: findLibrary returned null
        at java.lang.Runtime.loadLibrary(Runtime.java:365)
        at java.lang.System.loadLibrary(System.java:535)
        at net.sqlcipher.database.SQLiteDatabase.loadLibs(SQLiteDatabase.java:141)
        at net.sqlcipher.database.SQLiteDatabase.loadLibs(SQLiteDatabase.java:136)

表示。所以在编译过程中没有附加文件。

it means .so files were not attached during compilation.

3的所有文件都存储在/库/ armeabi /目录。

all 3 files are stored in /libs/armeabi/ directory.

我认为这个问题是我用maven来管理依赖关系（采用Android工作室反正进行建设）。接下来的尝试 - 包括那些库到Maven的依赖关系。据<一href="https://$c$c.google.com/p/maven-android-plugin/wiki/NativeLibsAsDependencies">documentation这是pretty的方便。我找不到他们在一个公共仓库，所以我用＆LT;范围＆GT;系统＆LT; /范围＆GT; 与标记。他们是可见的，但没有奏效。后来发现<一href="http://grokbase.com/t/gg/maven-android-developers/1342a8mh4h/native-libraries-from-local-path">this链接，据说范围制度将无法正常工作，尝试添加这些库到本地存储库中使用

I assumed that the problem is that I use maven to manage dependencies (building is performed using Android Studio anyways). The next try - include those libraries into maven dependencies. According documentation it is pretty easy. I couldn't find them in a public repository so I used <scope>system</scope> with a tag. They were visible but it didn't work. Later found this link where it is said that scope "system" won't work, tried adding those libraries into local repository using

mvn install:install-file -DgroupId=net.sqlitecipher -DartifactId=stlport_shared -Dversion=1.0 -Dfile=libstlport_shared.so -Dpackaging=so -DgeneratePom=true

到底 - 它不工作

in the end - it didn't work.

另外，我看到这个<一href="http://stackoverflow.com/questions/16683775/include-so-library-in-apk-in-android-studio/17131418#17131418">topic,也许这是一个解决方案，但我不使用当前摇篮。有没有一种方法，包括.so文件到APK没有从行家移动到摇篮？

Also I saw this topic, probably this is a solution but I don't use gradle currently. Is there a way to include .so files into the apk without moving from maven to gradle?

据我了解的Andr​​oid Studio使用摇篮内部建立的apk，所以使用Maven我所有的努力都是没有用的，直到他们开始支持本地库，对吗？我也曾尝试建设项目的IntelliJ IDEA Cardea（13.0），可惜没有成功。

As I understood Android Studio uses gradle internally to build apks, so all my efforts with maven are useless until they start supporting native libraries, am I right? I have also tried building the project with Intellij IDEA Cardea (13.0), unfortunately without any success.

推荐答案

只要本地库在/库/ armeabi /所有你需要做的就是正确配置的Andr​​oid插件。事情是这样的：

As soon as the native libs are in /libs/armeabi/ all you have to do is to configure the android plugin properly. Something like this:

<plugin>
    <groupId>com.jayway.maven.plugins.android.generation2</groupId>
    <artifactId>android-maven-plugin</artifactId>
    <configuration>
         <nativeLibrariesDirectory>${project.basedir}/libs</nativeLibrariesDirectory>
         ...
    </configuration>
    <extensions>true</extensions>
</plugin>
