在Android Studio中加载运行时库时出错

Question

在我的android项目中,我使用的是外部jar库,它使用运行时库libiconv.so.我的库包含在项目的lib目录中.该库包含在以下目录hirarcy中的所有三种体系结构中.

libs>
armeabi>libiconv.so
armeabi-v7a>libiconv.so
x86>libiconv.so

但我得到了log cat记录的异常:

在CameraActivity.java:30的位置是:

static { System.loadLibrary("libiconv.so"); }

我也试过了

static { System.loadLibrary("iconv"); }

是否与gradle配置有关,因为我是Android Studio新手,或者错误来源是其他什么？

尝试使用ZBar SDK时遇到同样的问题.您很可能需要编辑build.gradle以确保APK中包含本机库.这就是我解决问题的方法:https://stackoverflow.com/a/16993006/2221876
