本地OpenCV的样品为Android抛出的UnsatisfiedLinkError [英] Native OpenCV Samples for Android throws UnsatisfiedLinkError

问题描述

我尝试在模拟器中运行OpenCV的机器人样品。与本地code例如样品样本教程2高级 - 1.添加本机OpenCV的失败。我有一个Win7 x86的系统。我可以建立本机库，但我总是得到以下异常，如果我运行该示例：

I try to run the opencv android samples on the emulator. The samples with native code e.g. sample "Tutorial 2 Advanced - 1. Add Native OpenCV" fails. I have a Win7 x86 System. I can build the native libs but i always get the following exception if i run the sample:

任何想法，如何解决这个问题？ 谢谢

Any ideas, how to fix this problem? Thanks

推荐答案

更​​改行

APP_ABI := armeabi-v7a

在 JNI / Application.mk 到

APP_ABI := armeabi

在默认情况下OpenCV的样本被配置为现代的ARMv7-A的硬件。

By default OpenCV samples are configured for modern armv7-a hardware.
