“Movesense ECG 样本不断停止”和错误“找不到 "libmds.so"

Question

我在 Windows 10（64 位）上使用 Android Studio 3.3 版。以下是发生错误的虚拟设备的特征：

Nexus 5X API28，Android9.0，CPU/ABI：x86
Nexus 5X API 28，Android 9.0，CPU/ABI：x86_64
Nexus 5 API 24，Android 7.0，CPU/ABI：x86
像素 API 27，Android 8.1，CPU/ABI：x86

Movesense移动图书馆版本：1.28.1.

我从 Movesense 网站 (https://bitbucket.org/suunto/movesense-mobile-lib/downloads/) 下载了 suunto-movesense-mobile-lib-e78baa174a4a 文件夹，并尝试运行 Android 的各种样本。我要展示的问题已记录在 ECGSample 中，但其他三个也出现过。应用程序构建正确，但是当我运行虚拟设备上的应用程序时出现以下错误：

安装失败并显示消息未能完成会话：

INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

（更改Android设备和API版本，出现同样的错误）。我解决了这个问题，将其添加到我模块的 build.gradle 脚本中 Android{} 块内：

 splits {
        abi {
            enable true
            reset()
            include 'x86', 'armeabi-v7a'
            universalApk true
        }
    }

执行此操作后，应用程序在虚拟设备上启动，但不幸的是立即崩溃。应用程序正确启动但立即关闭并显示以下消息：

" Movesense ECG sample keeps stopping".

通过检查 Logcat 我有以下错误：

为了找出真正的问题，我们调试了程序，它得到一个错误，错误是“找不到"libmds.so"。详情：

System.loadLibrary(mds) FAILED!

发生错误的代码。

private native void sdsSetDelegate(Object var1);

static {
    try {
        Log.d("SDSInternalWrapper", "Start load library call [mds]");
        System.loadLibrary("mds"); (Error occurred)
        Log.d("SDSInternalWrapper", "Finished load library call [mds]");
    } catch (UnsatisfiedLinkError var2) {
        String error = String.format("System.loadLibrary(mds) FAILED! Error: sds: %s", var2);
        Log.e("SDSInternalWrapper", error);
    }

}

Answer 1

在展示应用程序的 build.gradle 中，mdslib-.aar 库应位于 Movesense 文件夹中，该文件夹相对于项目位于“../Movesense/”，或者如果您正在尝试其他示例它应该位于“../../../Movesense/”，你把它放在那里了吗？

如果不是，请尝试保持此处的文件夹结构https://bitbucket.org/suunto/movesense-mobile-lib/src/master/android/

|_Movesense/ 
| |_libmds-<version>.aar
|  
|_Showcasapp/
| |_gradle/
| |_src/
| |
| 
|_Samples/

Answer 2

当前的 MDS 不支持 x86 或 x64，这就是您收到 UnsatisfiedLinkError 的原因。因此暂时无法与Android模拟器一起使用，只能在设备上调试。
