@madeye @Mygod I can reproduce in xiaomi Android 7.1.2 with same error above , by the way , tag 4.8.5 works fine . So maybe due to this commit Refine code style like didi-droid said

问题由 4e23960 引入，AndroidX团队已取消此替换建议：https://issuetracker.google.com/issues/142601969#comment3 。

撤销修改直到aapt2支持，或添加keep规则。

Nice. Thanks guy.

[madeye]

Let's wait for next release of aapt2.

found it.this issue occurs when you build release version,
so the proguard-rules.pro should be add :
-keep class com.google.android.material.** {*;} -keep class androidx.** {*;} -keep public class * extends androidx.** -keep interface androidx.** {*;} -dontwarn com.google.android.material.** -dontnote com.google.android.material.** -dontwarn androidx.**

to avoid the fragment being obfuscated.
