1 year ago I am running quite a bit behind schedule.The reason for that is that not all the captures are running properly. In a folder of about 45 apps, I am finding only 35 work. Then I have to manually go through the rest of the 10 to find out what went wrong.
The way I am telling if something went wrong is if the “har” file is in bytes, or the “mitm” file is around 11kb for several captures of the app. This is the usual traffic that is captured without running any app. Sometimes, the case is simply that the app does not transmit data, but most of the times it means the apk was not installed properly.
I have found several main reasons for these apks not being installed correctly:
-
There is a split apk folder and a normal apk for the same app. My code by default looks for the apk, and usually this leads to problems. This one can be fixed by making split apks the default.
-
Sometimes, inside a split apk folder, there are duplicates of the same config files, say “v8a”, and these cause installation problems (notice how the duplicates have different dates as well). Additionally, as can been seen in the screenshots below, there are some stray files with no extension. I have no idea what role these play.
-
The third problem is that sometime the apks are entirely missing even though the set should be full. Ex. “com.catdaddy.nba2kmcom.ea.tsb” in “GAME_SPORTS”.
The above mentioned are the frequently occurring problems.
Apart from these, I once saw an xapk, but that may just be a one off. Nevertheless, we need to take care of these problems ASAP for the captures to run efficiently.

I am opening this issue to document problems that come along as I am collecting data, and to keep track of progress.
