Question

我的设定为流动：

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.i添加此＆＃34; android.useDeprecatedNdk = true＆＃34;在＆＃34; gradle.properties＆＃34;

3. NDK路径也设置正确

4.c ++源代码

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

5. MainActivity使用：

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

6. eroor信息：
