android – 2016-10-05安全补丁级别打破Nexus-9 Xamarin

2019年7月20日 253次阅读

在使用Xamarin Forms 2.3进行安全更新后,我的应用程序仅针对Nexus 9发生了以下崩溃.它适用于我的Pixel-C,三星S2,三星标签A和戴尔Venue这让我感到困惑.这仅发生在2016-10-05安全补丁之后.我有2个Nexus 9,并确认它在补丁之前正在工作.

任何帮助将不胜感激.

最佳答案 你在你的应用程序中使用sqlite吗？在将其升级到Android 7.0后,我们的Nexus 9遭遇了类似的崩溃.原来,我们的自定义sqlite库没有包含64位文件.即使应用程序包含arm64-v8a选项,32位sqlite库也会强制应用程序加载armv7 / 32位库.

一旦我们使用64位libsqlite.so文件重建自定义sqlite库,并使用新的sqlite库重建应用程序,我们就不会再崩溃了.

另请查看Xamarin关于链接Android 7.0中的更改的本机库的帖子.
