Question

当用户通过Fabric的Beta安装我的应用程序导致安装失败时，我遇到了这个奇怪的错误。这似乎只影响三星设备。

还有其他人看过这个或知道可能导致它的原因吗？感谢

Answer 1

我们与Samsung特别针对Fabric Beta存在类似的安装问题。

我们android:extractNativeLibs="false"时发生了这种情况 - 在Android Studio的最新版本开始建议将其作为lint修复程序之后。

所以解决方法/修复直到Fabric修复此问题是为了确保android:extractNativeLibs="true"

Answer 2

尝试

I had the same problem when I built my app with only V2 (Full APK Signature) option in Studio. I have now selected V1 (Jar Signature) and V2 (Full APK Signature) and it works.

有同样的问题，这解决了我的问题。来自Cannot update the app after updating SDK (app not installed) ..

通过Fabric Beta安装应用程序时解组时找不到类
