OpenCV的样品获得＆QUOT;无法建立BuildConfig类＆QUOT; [英] OpenCV samples get "Failed to create BuildConfig class"
问题描述
我目前正在运行OpenCV的样本为Android找到<一href=\"http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.3.1/OpenCV-2.3.1-android-bin.tar.bz2/download\"相对=nofollow>这里（我曾尝试与较新版本，但我跟着从<一的建议href=\"http://stackoverflow.com/questions/9198949/errors-importing-opencv-in-eclipse-wont-go-away\">this问题的答案）和我跑入误差
I am currently trying to run the OpenCV samples for Android found here (I have tried with more recent versions, but I followed the suggestion from this question's answer) and am running into the error
无法创建BuildConfig类
Failed to create BuildConfig class
以及
OpenCV的-2.3.1] Android的要求编译器遵从性级别5.0或6.0。找到1.7来代替。请使用Android工具>修复项目
OpenCV-2.3.1] Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project
有关在第一个错误;我仍然无法找到一个解决方案;我试着在更换最新的OpenCV的建议（2.3.1）在答题<一个href=\"http://stackoverflow.com/questions/9198949/errors-importing-opencv-in-eclipse-wont-go-away\">mentioned上述而不是2.4.2（也试过2.4.0）。答案建议使用2.3.1确切的版本，但到目前为止，它似乎并没有这样的伎俩。
For the first error; I still cannot find a solution; I've tried replacing the latest OpenCV with that suggested (2.3.1) in the answer mentioned above instead of 2.4.2 (also tried 2.4.0). The answer advised to use the exact version 2.3.1, but so far it doesn't seem to do the trick.
有关在第二个错误，我想建议以下<一个href=\"http://stackoverflow.com/questions/7637144/android-requires-compiler-compliance-level-5-0-or-6-0-found-1-7-instead-plea\">here通过调整的 JDK compilance 的版本，而且这一问题还没有得到解决。
For the second error, I tried following the suggestion here by adjusting the JDK compilance version but also that problem hasn't been solved.
下面是一些错误的快照：

- Eclipse Indigo
- Windows7- 64bit
我找不到多少帮助网上的问题，我一直在寻找出办法解决它有一段时间了。我跟着<一个具体步骤href=\"http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/android_binary_package.html#get-the-opencv-package-for-android-development\"相对=nofollow>其中误差项确实是预期和看似简单的教程来消除，但他们没有那些问题本教程（下载完NDK最多时达到了这一点）。
I couldn't find much help online for the problem, I've been looking out for a way around it for some time now. I've followed the exact steps in this tutorial (done downloading the ndk and reached up to this point) where errors were indeed anticipated and seemingly easy to eliminate in the tutorial, but they're not as those in question.
感谢您提前。
推荐答案
下面是三种解决方案，结合，似乎做的伎俩（消除错误）。
Below are three solutions that, combined, seemed to do the trick (to eliminate the errors). The samples work fine now (tested on an Android 2.2 phone):

I've noticed a line in this tutorial (seems as another version of that linked in the question) stating

为什么错误消失的原因之一，因为我之前做了这个步骤
移动OpenCV库到Eclipse工作区没有检测
在据我记得之间的样本项目。
I've also installed Android API 11 from the SDK manager (earlier I've only installed the API levels 8 and 16) which was the recommended minimum level in the tutorial. The mere installation was a step I've made as suggested in an answer to this question where the question referred to an error similar to one of those I've found trying to build the samples. I am unsure however whether this was one of the reasons why errors faded, since I did this step before moving the opencv library to the eclipse workspace with no testing of the sample projects in between as far as I recall.

I've tested the samples on an Android2.2 (API level 8) phone however(not emulator. I'm not sure if that's possible since in this tutorial it mentioned that only sample projects Tutorial 0 and Tutorial 1 would work on an emulator, from my experience so far neither have), which is also the minimum API level (8) currently set in my opencv samples' manifest files, and it worked.
最后，我不得不保持这个错误;
Lastly, I had this error remaining;

这是我为让OpenCV的样本为Android工作经验。
That was my experience for letting the OpenCV samples for Android work.
