  player.normal.np(NP管理器)

Additionally, you can see in -h that the new options provided by frida-dexdump are:

-o OUTPUT, --output OUTPUT  Output folder path, default is './<appname>/'.
-d, --deep-search           Enable deep search mode.
--sleep SLEEP               Waiting times for start, spawn mode default is 5s.

When using, I suggest using the -d, --deep-search option, which may take more time, but the results will be more complete.
