我正在尝试运行从http://code.google.com/p/android-anpr/source/下载的ANPR项目。
当我尝试执行该应用时，该应用正在关闭 。
我试图调试它，但看起来问题来自NativeGraphics.yuvToRGB(data, preview.cs.width, preview.cs.height);，我无法弄清楚为什么。
如果有人可以花一些时间尝试运行它并与我讨论错误，那真的很棒。在我看来，有一些缺少库或错误的实现。
答案 0 :(得分：0)
我遇到了同样的问题 - 尝试更改NDK的工具链。我相信它默认设置为arm-linux-androideabi-4.6，但是如果你把它改成arm-linux-androideabi-4.8它应该可以工作。
答案 1 :(得分：0)
您可能想查看OpenALPR（http://www.openalpr.com）。它应该在NDK下编译，并为您提供更准确的读数。它可能也快一点。
答案 2 :(得分：0)
我遇到了类似的麻烦;顺便说一句，日志中有信息，但它不会显示为错误，也不会显示为与应用程序相关...您真的需要注意。对我来说，简短的版本是这样的：graphics_core.cpp中有一些汇编代码需要你拥有一个支持NEON的ARM内核。日志消息说我的是，但SIGSEV发生在那里的某处，所以我不相信汇编代码是正确的（似乎是读取它不拥有的内存）。值得庆幸的是，有一个简单的方法：在GraphicsCore :: yuvToRGB替换：
#ifdef __ARM_NEON__
使用：
#if 0
将使用else分支中的代码。我还没有正确地识别任何牌子，但它根本不识别我所在地区的盘子，所以我不打算进一步研究它。
顺便说一句，日志消息看起来像这样：
