java.lang.UnsatisfiedLinkError：dlopen 64位而不是32位，而.so应该在x86中构建

我试图在Android Studio中使用JNI，我在默认情况下由Android Studio创建的示例native-lib.cpp下添加了JNI函数（添加C支持后）

但是，我面临一个错误

java.lang.UnsatisfiedLinkError：找不到boolean com.example.user.project.Tracker.isTracking_0（boolean）的实现（尝试过Java_com_example_user_project_Tracker_isTracking_10和Java_com_example_user_project_Tracker_isTracking_10__Z）

我还尝试将其添加到MainActivity中

static {
        System.loadLibrary("tracker");
   }

但我会得到另一个例外

java.lang.UnsatisfiedLinkError：dlopen失败：“/ data / app / com.example.user.project / lib / x86 / libtracker.so”是64位而不是32位

我可以看到我的库已经成功构建，这是它在构建时显示的轨道消息

这是我的CMakeLists

set (pathToOpenCv /home/user/OpenCV-android-sdk3.2)
set (pathToProject /home/user/AndroidStudioProjects/project)

cmake_minimum_required(VERSION 3.4.1)

set(CMAKE_VERBOSE_MAKEFILE on)

include_directories(${pathToOpenCv}/sdk/native/jni/include)

FILE(GLOB_RECURSE cppfiles "src/main/cpp/*.cpp")

add_library(lib_opencv SHARED IMPORTED)

add_library(tracker SHARED ${cppfiles})

set_target_properties(lib_opencv PROPERTIES IMPORTED_LOCATION ${pathToProject}/app/src/main/jniLibs/${ANDROID_ABI}/libopencv_java3.so)

find_library(
              log-lib
              log )
target_link_libraries( tracker
                       ${log-lib}
                       lib_opencv
                       )

这是我的native-lib.cpp

#include <jni.h>
#include <string>
extern "C"
JNIEXPORT jboolean JNICALL Java_com_example_user_project_Tracker_isTracking_10
        (JNIEnv *env, jboolean boolean) {
    printf("\n c-boolean: %d ", boolean);
    if (boolean == JNI_TRUE) {
        printf("true");
    } else {
        printf("false");
    }
    boolean = false;
    return boolean;
};

那么Android studio无法从我的.so库中找到该方法，并出现java.lang.UnsatisfiedLinkError的原因是什么？另外，我不知道为什么我的x86库是64位而不是32位 .

谢谢

UPDATE

只需仔细检查android日志，我认为它没有正确加载跟踪库 . 我认为现在64位错误是主要问题 . 更新问题 Headers

java.lang.UnsatisfiedLinkError：dlopen失败：“/ data / app / com.example.user.project / lib / x86 / libtracker.so”是64位而不是32位

在build.gradle中我设置了abiFilter，而我的AVD是x86设备
