运行Android原生code是导致java.lang.UnsatisfiedLinkError中 [英] Running android native code is causing java.lang.UnsatisfiedLinkError

问题描述

我有本土code，其中我使用OpenCV库的Andr​​oid应用程序。当运行在所有的手机应用程序运作良好，但是当我尝试在平板电脑（联想瑜伽2 PRO）我遇到这个错误运行它：

I have an android app with native code where I use openCV library. When running the app in phone everything is working well but when I try to run it on tablet(Lenovo yoga 2 pro) I am encountering this error:

这是上线45 SplashActivity：

this is on the line 45 in SplashActivity:

System.loadLibrary("native_module");

有人可以帮助我解决这个错误？或者我是什么做错了吗？

Can someone help me to solve this error? or What am I doing wrong?

推荐答案

您的平板电脑是基于英特尔Atom处理器。你必须建立您的 native_module 为 APP_ABI = 86 。请注意，您还需要的OpenCV的兼容版本。

Your tablet is based on Intel Atom CPU. You must build your native_module for APP_ABI=x86. Note that you also need the compatible version of OpenCV.

更新：在这种特殊情况下，应用程序是专为x86和ARM。但应用程序安装程序选择了错误的子文件夹，也许是因为文件名中的库/ 86 和库/ armeabi did不完全匹配 的。对于具有不平凡的本地组件应用的可靠和有效的方法是上传单独的APK到Play商店中。

Update: in this particular case, the app was built for both x86 and ARM. But the app installer chose the wrong subfolder, maybe because the filenames listed in libs/x86 and libs/armeabi did not exactly match. The reliable and efficient approach for apps that have non-trivial native component is to upload separate APKs to PlayStore.
