TLDR it's a spyware. It'd be great if someone could perform HTTPS interception to see what kind of data is sent to ads services.
Thanks ETFbitcoin,
As I said before in the first post, this can be some sort of malware/spyware.
I know we can use PEiD/PEBrowse Professional/PE Explorer/Strings v2.53(by Microsoft) in order to track the executable file (.EXE) on windows. Also we can use decompilers and dissemblers to check the assembly codes (lower lever language codes) to find the malware possible patterns.
But unfortunately, I don't have much info about how to analyze the APK files. This could be really nice if someone analyze the APK file and monitor the actions just like what you done here. Much appreciated for it.
