问题描述
三天前我已经迁移到SDK Android 27.1.0，并且出现了类似这样的崩溃，我不明白为什么.它(当前)显示在Android 8和6上.
I've migrated to SDK Android 27.1.0 3 days ago, and there are some crashs like this one, I can't understand why. It appears (currently) on Android 8 and 6.

这是我的适配器:

}
}
您有一些想法可以解决此问题吗?
Have you got some ideas guys to fix this problem?
非常感谢！
推荐答案
@XJIOP说的是正确的，我在生产中也遇到了同样的问题，但是我找不到崩溃的原因，我遵循@XJIOP路径并产生了错误，我通过更新精简版解决了该错误来自
@XJIOP said is correct i also have same issue on my production, but i was unable to find what the crash, i followed @XJIOP path and produce the bug,i resolved the bug by updating the compact version from
appcompat 27.1.0至27.1.1
appcompat 27.1.0 to 27.1.1
因为我使用的是proguard，所以我还在proguard中添加了以下行
since i am using proguard i also added the following line to my proguard
如果在生产版本上使用proguard，则将以下行添加到proguard，否则忽略
add the following line to proguard if you are using proguard on your production build else ignore
-keepnames class * implements android.os.Parcelable {
public static final ** CREATOR;
}
添加专业防护线并更新了压缩库之后，我得以解决该问题，并且在更新后的生产版本中仍报告了该错误.希望这对其他人有帮助
After adding the pro guard line and updating the compact lib i was able to fix the issue and the bug hasent reported yet on my updated production build. hope this will help some others
