[Soot-list] Help regarding Call graph for multiple apk's

[Steven Arzt]

Hi Lokesh,

Your best bet is indeed to call soot.G reset() before every new analysis, i.e., whenever you analyze a new file in your loop.

Best regards,
Steven

Please help me to generate the call graph for multiple applications as i have to generate the call graph for around 3000 applications and it would be practically impossible to manually generate call graph for each application.
