android - PJSUA2 sip android 原生应用

Question

在这里，我正在为 android 的 ubuntu 14.04LTS eclipse adt 中使用 native android 开发一个应用程序。

构建、配置并使一切变得完美。

之后，我将 pjsua2 示例应用程序导入 Eclipse，然后添加了 native 库支持，但是当我在模拟器上运行时，它会引发错误。

错误日志，

Answer 1

java.lang.UnsatisfiedLinkError: Couldn't load libpjsua2.so from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/org.pjsip.pjsua2.app-2.apk"],nativeLibraryDirectories=[/data/app-lib/org.pjsip.pjsua2.app-2, /vendor/lib, /system/lib]]]: findLibrary returned null

我有同样的错误。
android 示例应用程序尝试加载此 libpjsua2.so 从 JNILIBs 文件夹路径中，但它找不到它，所以它抛出了上述错误。希望我的回答对某人有所帮助。
