Question

我想在我的项目中使用该库进行编辑。因此，我安装了NDK并设置了NDK-bundle路径。但是这个错误出现在我的日志中。

这是开源库中的ArmArchHelper.class。

package FFmpegAndroid.src.main.java.com.github.hiteshsondhi88.libffmpeg;

class ArmArchHelper {
static {
    System.loadLibrary("ARM_ARCH");
}

native String cpuArchFromJNI();

boolean isARM_v7_CPU(String cpuInfoString) {
    return cpuInfoString.contains("v7");
}

boolean isNeonSupported(String cpuInfoString) {
    // check cpu arch for loading correct ffmpeg lib
    return cpuInfoString.contains("-neon");
}

}

这是ini文件夹中库中的armArch.c。

#include <jni.h>
#include <stdio.h>
#include <stdlib.h>
#include <cpu-features.h>

 JNIEXPORT jstring JNICALL
  Java_com_github_hiteshsondhi88_libffmpeg_ArmArchHelper_cpuArchFromJNI(JNIEnv* env, jobject obj)
{
char arch_info[11] = "";

// checking if CPU is of ARM family or not
if (android_getCpuFamily() == ANDROID_CPU_FAMILY_ARM) {
    strcpy(arch_info, "ARM");

    // checking if CPU is ARM v7 or not
    uint64_t cpuFeatures = android_getCpuFeatures();
    if ((cpuFeatures & ANDROID_CPU_ARM_FEATURE_ARMv7) != 0) {
        strcat(arch_info, " v7");

        // checking if CPU is ARM v7 Neon
        if((cpuFeatures & ANDROID_CPU_ARM_FEATURE_NEON) != 0) {
            strcat(arch_info, "-neon");
        }
    }
}
return (*env)->NewStringUTF(env, arch_info);
}

如果您现在如何解决此问题，请告诉我。谢谢。

您是否将armArch.c文件编译到libARM_ARCH.so中？其他如果要编译为说libsomething.so，则将命令更改为System.loadLibrary（“ something”）

如何使用JNI，NDK导入开源库
