Java 不能'；“找不到”；libjniopencv_core.so“；

我正在用opencv开发一个android应用程序，我遇到了一个问题

我遇到的错误是：

这是设置.graddle文件：

include ':app', ":common", ":commonwidget", ":panowidget", ":base"

在我添加包“base”之前，一切都很正常

提前感谢您的帮助：D

编辑：多亏了@Prateek answer，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，因为我没有所有需要的版本（arm64-v8a、armeabi、armeabi-v7a…），特别是关于我手机的版本。所以我试着从这里下载，但文件不是共享对象。所以是静态的。所以它不工作。。。有人能帮我吗？：）

解决方案：我只有32位版本的库文件“.so”。所以我所做的就是，像@Prateek所说的，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”应用程序文件中添加ndk规范来强制使用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"
         }
       }
    }

希望它能帮助别人：）

你把libjniopencv_core.so文件放在JNI文件夹中了吗

我刚试过，现在错误变了，它说“由以下原因引起：java.lang.unsatifiedlinkerror:dlopen失败：”/data/app/com.sogeti.innovation.obcapture-1/lib/arm64/libjniopencv_core.so“是32位而不是64位”我认为“是”基数“我添加的包是64位的，但我的是32位的，或者类似的…嘿@Pratek，我想我理解版本问题，但现在还有一个问题，你能看看我的答案吗？”？谢谢：）如果你自己创建了android.mk文件，请共享这些文件的代码。我在jni文件夹中没有这样的文件

    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"
         }
       }
    }
