android - GNSDK for Android 在 x86 AVD 上崩溃

Question

在 x86 AVD 上运行时，适用于 Android 的 GNSDK 示例应用程序因信号 4 (SIGILL)、代码 2 (ILL_ILLOPN) 而崩溃。我在 API 级别 22 和 25 上尝试了 Nexus 5 AVD 和 Pixel XL AVD，只要示例应用程序尝试在 onCreate() 中使用 native GNSDK 库，就会发生相同的 SIGILL 崩溃。从回溯来看，看起来 libgnsdk_storage_sqlite.3.12.1.so 特别可能是罪魁祸首。当我使用适用于 x86 的 GNSDK native 库时，我自己的应用程序中也会发生同样的崩溃，因此问题不是示例应用程序所独有的。这可能是什么原因造成的？

我已经确认示例应用程序适用于 arm 硬件和 arm AVD。我没有任何 x86 硬件，所以我无法确认这是否真的是 x86 ABI 问题，还是 AVD 与真实硬件的一些奇怪之处。

Answer 1

也许不是一个好的答案，但如果你评论电话

GnStorageSqlite.enable();   
GnLookupLocalStream.enable();

示例应用程序使崩溃消失并且在线查找仍然有效。我猜这些调用必须使用与 x86 有一些不兼容的本地库。
