THREAD: I'm looking at a Huawei P20 from China, let see what can I found

The 1st app I reversed is an app called Decision
Look at the name of the files contains in the assets folder:
- airport_china.txt
- city_china.txt
- cityinfo.db
- parkinglot_china.txt
- railwayinfo.db
- trainInfo.db
- trainstation.db

Interesting, no?
For example, the trainstation database contains:
- address
- name
- latitude
- longitude
- city
In the manifest of this application, there is a GeoReceiver
This receiver is receiving an UUID and will lookup an known fence id
I'm a stupid security researcher. For the moment, the keywords are: train, airport, city, geo fence... Do you see where we are going?
In the data folder, there is a file called CalcMain. Here some of the methods of this class:
- callGetBusTime
- callGetTaxiTime
- isTrafficBusy
- callGetHomeCity
- callHasHotelTicket
- callGetAirportMultiPoi
- callHasGroupBuyingTicket
- ...
Nice data types haha
To be clear, this app is composed of 3 background services and 2 services. There is NO UI in this app.
Please be nice "DO NOT KILL ME >_<"
This is the kind of function that I love to find
This app doesn't seems to send the data BUT they communicate with another service called HiActionService which is coming from an Huawei app called HiAction
The previous screenshot is from the class called ActionCommonUtil. We can easily that Decision is sending all his events to this service through the methods in this class.

'Om' is the sound of the Universe. It's the first original vibration of the nothingness through which manifested the whole Cosmos. It represents the birth, death and rebirth process. Chanting 'Om' brings us into harmonic resonance with the Universe. It is a scientific fact.

Therefore, Mantras are described as vibrational words that are recited, spoken or sung and are invoked towards attaining some very specific results. They make very specific sounds at a frequency that conveys a directive into our subconcious.
