更新： 我向谷歌提出了一个问题： 链接：

虽然我觉得实现这一点的工具已经可用（Gradle、CMake、NDK等）

还感谢@Anirudh让我知道这是安卓N上的一个已知问题

在我的设备上发布即时应用程序而没有C++库吗？ 是的。。。如果我创建了一个新的Android Studio项目，只支持
包含Android即时应用程序
，它将发布到我的三星Galaxy 7S上，并显示“Hello World！”屏幕

发布已签名的APK有效吗？

生成签名的APK作品，检查时，本地C++库与特征调试.APK< /COD>捆绑，但不是<代码>基础调试。这是我在gradle配置下所期望的，但没有解释为什么它不会发布到设备/模拟器

我还没试过侧装这些APK。。。但我怀疑这是否可能，因为即时应用程序从未安装过。。。你甚至会在侧面加载它（点击一个url）后如何启动它

是否将C++库添加到APKs的两个工作中？
我已尝试将
externalNativeBuild
gradle属性添加到
base/build.gradle
和
feature/build.gradle
文件中，但仍然出现相同的错误。在生成签名APK之后，通过检查<代码>特性调试> APK<代码>和<代码>基础调试.APK < /代码>，验证了本机C++库是否被包含在两个AKS中。
修改基础/构建。渐变：

发布已签名的APK有效吗


Android Studio 3.0预览生成签名的APK功能目前有一个bug，最终的zip没有包含所有的APK功能。在每个功能模块的Gradle文件中使用Gradle SigningConfig对功能APK进行签名


是否将C++库添加到APKs工作？

不需要。添加到基本特性apk就足够了


实际崩溃是由于Android M/N上的NDK对Android即时应用程序的支持而引起的。该应用程序在Android O emulator上运行
的“发布”意思是说部署到Google Play Store吗？您可以使用Apk Analyzer检查您的即时应用程序zip文件，以确保您的库已绑定。@Anirudh所说的“发布”是指设备或模拟器。。。编辑问题，谢谢@Anirudh我能够生成一个签名的APK，检查后，库与feature-debug.APK捆绑在一起，而不是base-debug.APK。这正是我在gradle配置下所期望的。Android Studio 3.0预览生成签名APK功能目前有一个bug，最终的zip没有包含所有的APK功能。在每个功能模块的Gradle文件中使用Gradle SigningConfig对功能APK进行签名。@Anirudh很高兴知道。。。但我真的不关心签署的APK在这一点上。。。我只需要在设备或模拟器上测试即时应用程序。
