Question

我是Android NDK开发的新手。今天我通过Android Studio向导设置了一个项目，与常见的Sdk开发有什么不同，我检查了“Include C ++ Support”。然后进入开发区，它告诉我gradle sync失败---“错误：预计调用者确保有效的ABI ：ARM64_V8A“。

我的发展环境是：

Android Studio2.2.2

JRE：1.8.0

操作系统：Windows 10家族版

错误日志如下：

var hub;
var url = 'http://localhost:44317/signalr';   
$.connection.hub.logging = true;
$.connection.hub.url = url;
var hub = $.connection.MyHub;
hub.client.ChangeStatus = function (status) {
    alert('new Status' + status);
};
$.connection.hub.start()
    .done(function () {
        alert('Now connected');
        hub.invoke('CheckConnectionStatus', '1');
    })
    .fail(function () { alert('Could not Connect!'); });

经过仔细搜索后，我发现它在build.gradle（app）中添加了一些内容

删除后，没关系。它的内容如下：

   externalNativeBuild {
    cmake {
        path "CMakeLists.txt"
    }
}

我已将其报告给Android Studio bug report。

我不知道这是不是我的错。感谢任何解释。

Answer 1

今天，当我导入＆＃34; echo＆＃34;一个例子，它警告我

错误：E：\ Android_Sdk \ ndk-bundle \ sources \ cxx-stl \ llvm-libc ++ \ libs \ armeabi-v7a \ libc ++ _ shared.so
中预期的NDK STL共享对象文件

搜索我的计算机和另一台计算机ndk-build目录后，我发现了问题。这是由于我的粗心造成的，我从另一台计算机上复制了ndk-build目录，但它并不是一个很好的副本。再次复制后，问题被驳回。

我为我的疏忽感到非常抱歉。我不知道是否需要删除此帖子。如有需要，请随时告诉我。
