Static Analysis of some apks takes too long

Nobody has claimed this yet.

When trying to run Qark on some applications with:

`qark --apk path-to-the-apk.apk` or `qark --report-type json --apk path-to-the-apk.apk`

I noticed that on some apks Static Analysis just takes too long.

For example, for an apk, I noticed that Static Analysis lasted about 8 hours, which is definitely too much. In this case, looking at the logs, I noticed that the Static Analyzer employed most of the execution time in the "Decompiling" stage, more specifically decompiling with "fernflower" was taking too long, thus I just removed fernflower from the decompilers dictionary and ran the Static Analysis again, getting a big improvement in the execution time.

Nevertheless, with some other apk, Static Analysis lasted too long again. More specifically I measured an execution time of about 5 hours, which is still too much... This time the Static Analyzer seems to employ almost all of its execution time in the "Running scans..." stage.

Could you explain the possible reasons for this behavior? Is there something I can do to improve execution time?

Thanks in advance

Reproduce the reported commands, `qark --apk path-to-the-apk.apk` and the JSON-report variant, while reviewing logs for the "Decompiling" and "Running scans..." stages. Inspect the decompiler configuration, including `fernflower`, and the scan execution path; done should be a documented cause and a defined way to reduce or explain the excessive runtime.
