jblas android错误

Question

我使用的是jblas 1.0.2，错误如下：

The library 'jblas-1.2.0.jar' contains native libraries that will not run on the device.
[2012-11-20 17:37:36 - com.hexar.filebroswer.activities.FileBroswerActivity] Additionally some of those libraries will interfer with the installation of the application because of their location in lib/
[2012-11-20 17:37:36 - com.hexar.filebroswer.activities.FileBroswerActivity] lib/ is reserved for NDK libraries.

我只使用FloatMatrix和eigen vectors类。

我必须安装NDK吗？将来的稳定性会不会有问题呢？

看起来您使用的jblas版本不是针对Android编译的。看看错误抱怨的不同路径:它们都被命名为"Mac /something“，或者"Linux/i386/something”等等……

在jblas.org上快速浏览一下，显然目前还没有针对安卓系统的预编译版本：

存在一个预打包的jar文件，其中包含预构建的本地库。目前包括Linux (i386/amd64)、Mac (i386/x86_64)和Windows (i386)。目前，仅有限地支持Windows上的amd64 (功能完整，但性能不同)。
