错误：当我在Android studio中使用NDK时

我的设置为流动：

1.app/build.gradle

defaultConfig {
    applicationId "demo.kid.com.testjni"
    minSdkVersion 19
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    ndk {
        moduleName "helloNDK"
    }
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

2.我在“gradle.properties”中添加了“android.useDeprecatedNdk=true”

3.NDK路径也已设置且正确

4.C++源< /P>

JNIEXPORT jstring JNICALL
Java_demo_kid_com_testjni_MainActivity_getStringFromNative
(JNIEnv *env, jobject){
    return env->NewStringUTF("Hello World From the JNI!");
}

5.主要活动用途：

static {
    System.loadLibrary("helloNDK");
}
public native String getStringFromNative();

6.ERO信息：

你的

Android.mk

文件是什么？需要mk文件吗？我看了视频，我跟着它做，他没有用MK文件。是的，你需要一个。
