已经安装好apk,刚打开就闪退，run记录上写着
E/cv::error(): OpenCV Error: Parsing error (Missing or invalid SVM type) in void cv::ml::SVMImpl::read_params(const cv::FileNode&), file /Volumes/Linux/builds/master_pack-android/opencv/modules/ml/src/svm.cpp, line 2122
求大神解释。。用windows平台和mac平台都显示这个错误信息。

可以识别的图片，处理正常；
不能识别的图片，程序直接退出。调试发现是byte[] resultByte = CarPlateDetection.ImageProc(imagePath, svmpath, annpath);这句导致的。不知道改怎么解决啊？？

应为手上的电脑没AS，有idea，所以能打开就不下AS了...

如果还有人能看到的话，请警戒，原项目导入，会出现严重问题。
我的导入环境是AS3.0.1，ndk19，除去其他无关的错误，直接在jni目录下使用ndk-build，会出现undefined reference to cv::imwrite的错误，该错误在我集成最新的easyPR也出现了（为了解决这个问题，我试了好几个版本的opencv，3.1，3.2都是会出现这个错误），很有可能是openCVforandroid 导入的错误。如果有人解决了这个问题，请message 我

老哥请问这个app怎么使用，只能拍照，怎么识别？

我把android的demo导入之后，没有报错，但是OpenCV的sdk没有用上啊，运行的时候报错
java.lang.UnsatisfiedLinkError: Native method not found: com.aiseminar.EasyPR.PlateRecognizer.initPR:(Ljava/lang/String;Ljava/lang/String;)J

OpenCV Error: Parsing error (Missing or invalid SVM type) in void cv::ml::SVMImpl::read_params(const cv::FileNode&), file /Volumes/Linux/builds/master_pack-android/opencv/modules/ml/src/svm.cpp, line 2122

这个是什么原因

按照要求一步一步走的 结果为0
另外一个问题：最后一步，复制的时候，项目本身有一个armeabi-v7a，拷贝的时候提示覆盖，是直接覆盖吗？

Android studio 提示找不到这个文件，gradle和AS都是最新版的，有什么解决办法吗

原项目重新编译生成armeabi so成功
可以识别原plate_locate图或者截取的一部分
但是从网络上下载一张含有车牌号的图片识别失败
错误信息：
Tag:libc
Message:Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 16368 (xample.carplate)

java.lang.UnsatisfiedLinkError: Cannot load library: soinfo_link_image(linker.cpp:1635): could not load library "libopencv_java3.so" needed by "libEasyPR.so"; caused by load_library(linker.cpp:745): library "libopencv_java3.so" not found

NDKR11 +　SDK23.01 +gradle2.1.0

编译的时候提示
Error:Execution failed for task ':app:buildNative'.

A problem occurred starting process 'command 'D:\android-ndk-r11/ndk-build''

这个需要更改路径么，我看路径是正确的
commandLine "$ndkDir/ndk-build",
'-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
'-j', Runtime.runtime.availableProcessors(),
'all',
'NDK_DEBUG=0'

车牌识别，只能传入图片路径吗？是否可以传入bitmap或者byte[]等其他形式。

Error:Execution failed for task ':app:cleanNative'.

Process 'command 'E:\Sdk\ndk-bundle/ndk-build.cmd'' finished with non-zero exit value 255

请问，这个是没有训练对应的SVM模型还是其他问题（比如图片过大等）。
希望大家给我解惑，谢谢。

扫描车牌的时候,需要对准车牌的上面才能扫描出结果,这个扫描框是不是得调整一下?

modify MainActivity.java
path = sdcard/EasyPR/

test image is jni/image/2.jpg

launch application, it is crash when I click the button.
following is log

编译的时候出现这个问题Error:Execution failed for task ':app:buildNative'：

如果是windows平台，解决办法是将 commandLine "$ndkDir/ndk-build"
修改为commandLine "$ndkDir/ndk-build.cmd"

一次也没成功，车牌后面的数据可以，前面的汉字一交也没正确过？

请问，如果将 EasyPR 项目移植到 Android 项目中？
博主能否写一下过程，这样以后 EasyPR 那边更新了，我们也可以自行更新到 Android 中。
谢谢！

你好，我编译总是报这个错误，可以帮我解答下是什么原因么。。

例如 "国 K123B4" 在训练数据里加的吗 是的话怎么加

我执行 ndk-build 提示 EasyPR_Android-master/obj/local/armeabi-v7a/objs/imageproc/core/ImageProc.o.d:1: *** multiple target patterns. Stop.

于是我打开这个文件，里面写的都是你原本电脑的绝对路径，我尝试修改成为我的路径，可我发现，不止这个文件，就连整个目录下都是你电脑的绝对路径。请问我是否全部要替换呢？

i modifed application.mk with APP_ABI := all ,then libEasyPR.so file only created successfully in armeabi-v7a/arm64-v8a. why not successful in x86 and other folders ?

编译的版本是EasyPR_Android.apk，大小有23m
放到应用太大了，能不能像CarPlant.apk那样，另外安装apk实现功能，可以让用户选择
虽然CarPlant.apk即使安装了opencv也不能用。。。
