HELLO-JNI样品不Android Studio中2.0 preVIEW工作 [英] Hello-jni sample doesn't work in Android Studio 2.0 Preview

问题描述

我想实现 hello- JNI 样品
到我的项目。我有摇篮 2.8和'com.android.tools.build:gradle-experimental:0.4.0 和使用 Android的工作室2.0 preVIEW 3B 。

I'm trying to implement hello-jni sample into my project. I have Gradle 2.8 and 'com.android.tools.build:gradle-experimental:0.4.0' and using Android Studio 2.0 Preview 3b.

这是我的的build.gradle ：

apply plugin: 'com.android.model.application'
model {
    android {
        compileSdkVersion = 23
        buildToolsVersion = "23.0.2"
        defaultConfig.with {
            applicationId = "lala.lala"
            minSdkVersion.apiLevel = 16
            targetSdkVersion.apiLevel = 23
            versionCode = 1
            versionName = "1.0"
        }
    }
    /*
    * native build settings
    */
    android.ndk {
        moduleName = "hello-jni"


        //  cppFlags.add("-fno-rtti")
     //    cppFlags.add("-fno-exceptions")
     //   ldLibs.addAll(["android", "log"])
      //  stl       = "system"

    }

    android.productFlavors {
        // for detailed abiFilter descriptions, refer to "Supported ABIs" @
        // https://developer.android.com/ndk/guides/abis.html#sa
        create("arm") {
            ndk.abiFilters.add("armeabi")
        }
        create("arm7") {
            ndk.abiFilters.add("armeabi-v7a")
        }
        create("arm8") {
            ndk.abiFilters.add("arm64-v8a")
        }
        create("x86") {
            ndk.abiFilters.add("x86")
        }
        create("x86-64") {
            ndk.abiFilters.add("x86_64")
        }
        create("mips") {
            ndk.abiFilters.add("mips")
        }
        create("mips-64") {
            ndk.abiFilters.add("mips64")
        }
        // To include all cpu architectures, leaves abiFilters empty
        create("all")
    }
    android.buildTypes {
        release {
            minifyEnabled = false
            //proguardFiles.add(file('proguard-rules.txt'))
        }
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.google.android.gms:play-services-ads:8.3.0'
    compile 'com.google.android.gms:play-services-analytics:8.3.0'
    compile 'com.google.android.gms:play-services-appindexing:8.3.0'
}

我在 JNI 文件夹中创建 HELLO-jni.h ：

在我的code的某些部分我导入此：

In some part of my code I import this:

static {
    System.loadLibrary("hello-jni");
}
public static native int testMethod();

和按 HELLO-jni.c 创建自动完成：

#include "hello-jni.h"

JNIEXPORT jintJNICALL
Java_lala_lala_HomeScreen_testMethod(JNIEnv
*env,
jclass type
)
{
// TODO
}

头文件 HELLO-jni.h ：

//
// Created by Filip on 15.12.2015..
//

#ifndef PHOTO_HELLO_JNI_H
#define PHOTO_HELLO_JNI_H

#endif //PHOTO_HELLO_JNI_H

但它不工作。它是全红：

But it doesn't work. It is full red:

推荐答案

这是在Android Studio中的问题，但只是在Windows上：<一href=\"https://$c$c.google.com/p/android/issues/detail?id=195483&q=label%3AReportedBy-Developer&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars\"相对=nofollow>问题195483

您可以降级到Android 1.5.1工作室，2.8的gradle，的实验包装0.4.0 。结果
我尝试过Android Studio 2.0测试版6，带包装 0.6.0-beta5的和0.6.0-beta6，但仍然无法正常工作。

It's problem in Android studio, but just on Windows: Issue 195483
You can downgrade to Android studio 1.5.1, gradle 2.8, experimental wrapper 0.4.0.
I tried Android Studio 2.0 beta 6, with wrapper 0.6.0-beta5 and 0.6.0-beta6, but still doesn't work.
