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.

I’m torn on how to approach the idea of luck. I’m the first to admit that I am one of the luckiest people on the planet. To be born into a prosperous American family in 1960 with smart parents is to start life on third base. The odds against my very existence are astronomical.

I’ve always felt that the luckiest people I know had a talent for recognizing circumstances, not of their own making, that were conducive to a favorable outcome and their ability to quickly take advantage of them.

In other words, dumb luck was just that, it required no awareness on the person’s part, whereas “smart” luck involved awareness followed by action before the circumstances changed.

So, was I “lucky” to be born when I was—nothing I had any control over—and that I came of age just as huge databases and computers were advancing to the point where I could use those tools to write “What Works on Wall Street?” Absolutely.

Was I lucky to start my stock market investments near the peak of interest rates which allowed me to spend the majority of my adult life in a falling rate environment? Yup.
