Android – ‘无法加载Foo：findLibrary返回null’

我知道关于堆栈溢出已经有关于这个错误的帖子,但是我在SO和Google上找到的并没有排除我的问题.

我正在尝试运行我的应用程序,但每当调用本机函数时,程序崩溃,我得到以下LogCat …

这是我的Android.mk文件：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
EXTRA_CFLAGS := -DANDROID
LOCAL_MODULE := RelayAPI
LOCAL_SRC_FILES := RelayAPI.c
include $(BUILD_EXECUTABLE)

这是我的jni文件夹的图片…将只使用RelayAPI,Stringstuff是一个未使用的额外文件.

我将所有本机函数存储在一个单独的类中,以便可以静态调用它们.这不是问题,因为我已经将它们移动了很多但我只是认为这将是我完成它的最佳方式.

public static class NativeCalls {

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

    public native static byte InitRelayJava();

    public native static void FreeRelayJava();
}
