android - Application stops before showing anything

问题描述

I've got some problems, only one for now.

I deploy my application to Google Play about 2 months ago, and yesterday I received an email relating the app does not open in a device and it break before open, showing on the screen "Unfortunately, (?) Has stopped". It runs normaly in another device, but not in the "J3 (2016) android version 5.11's user".

I opened the Google Play Console, and looked for answers in ANR's menu. I found this:

**java.lang.NoSuchMethodError:**

I'll try to reproduce this error via android emulator. Does anybody seen this before, know how to solve and can help me?

Thank you guys.

解决方案

看起来您正在使用 Android 5 不支持的应用程序的本机代码执行某些操作。从出现的评论中，您可以在模拟器中重现此内容。因此，找出问题所在的下一步是查看您的本机代码，甚至在您的模拟器中使用本机代码调试来找出它失败的原因。

这里有一些关于Androud Studio 中本机代码调试的文档。
