Hello Huawei team! I'm getting this error, I don't know how to solve it, I can't find these classes in dependencies, please help me!

@GulmirzaNorboyev Dear developer,

Please confirm the following questions:

1. For unknown source problems, please check whether confusion is enabled. If confusion is enabled, please add a confusion rule script;
   

2. For the error of null pointer, please check whether there is any key information in these two lines of code.

1. I can't find the classes in the com.huawei.hms.maps.provider.* package, the solution I did now was to add this line to the proguard file: -keep class com.huawei.hms.maps.**{*;}
2. I couldn't find these classes either. ☹️

@GulmirzaNorboyev Dear developer,
Can you solve the problem of Unknown Source after adding the "- keep class com. huawei. hms. maps. * * {*;}" confusion script?
In addition, "ij.c.e mj.d.c jjj.g $a.e" and other items are not the package names of HMS Core, which may need you to look again.
