我正在使用opencv开发一个Android应用程序而且我遇到了问题......
我遇到的错误是：

这是 settings.graddle 文件：

在我添加“base”包之前，一切正常。
先谢谢你的帮助：D
编辑：感谢@Prateek的回答，我创建了JNILibs文件夹，然后添加了所需的.so文件。但是有一个问题，因为我没有所需的所有版本（arm64-v8a，armeabi，armeabi-v7a ......），尤其是关于我的手机的版本。所以我试着从这里下载它，但文件不是共享对象.so但是静态.a所以它不起作用...任何人都可以帮助我吗？ ：）
解决方案：我只有32位版本的库文件“.so”。所以我所做的就像@Prateek所说的那样，将这些文件放在文件夹“JNILibs”的子文件夹“armeabi”，“armeabi-v7a”，“mips”和“x86”中。然后我通过在“build.graddle”app文件中添加 ndk 规范强制使用32位文件，如下所示。
android {
compileSdkVersion 24
buildToolsVersion '25.0.2'
defaultConfig {
applicationId "com.sogeti.innovation.obcapture"
minSdkVersion 19
targetSdkVersion 22
versionCode 1
versionName "1.0"
multiDexEnabled true
jackOptions {
enabled false
additionalParameters("jack.incremental" : "true")
}
ndk {
abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
}
}
}
希望它可以帮助某人：）
答案 0 :(得分：0)
你把libjniopencv_core.so文件放在JNI文件夹中了吗？
