运行demo找不到动态库为啥，是动态库没生成吗？

使用小米3移动版手机

build.gradle下要修改，编译jni。 库里面有提供so库，也可直接使用。

跟这个应该没关系吧。

刚试了下，用小米5s没问题。 小米 3用的 英伟达 的cpu. 是不是 这个 不太兼容

bjhexn avatar Nov 08 '16 06:11 bjhexn

编译jni可以选择目标平台的。默认是armbi，也可以加入x86 x86_64这些。只要C的代码能兼容就行~

smuyyh avatar Nov 08 '16 08:11 smuyyh

armbi 的话，理论是所有平台都可以的吧。 我用的小米3 ，还有个努比亚的 都不行。BAT是如何 兼容 这些的 呢

bjhexn avatar Nov 10 '16 10:11 bjhexn

@bjhexn 貌似系统检察ELF文件中的e_machine字段的值，armeabi也并非完全兼容吧，可以尝试吧各个平台的都编译一下。 'x86', 'x86_64', 'armeabi-v7a', 'arm64-v8a'
