[Soot-list] Android instrumentation: No main class given. Inferred [..] as main class.

[Bodden, Eric]

Hi Jose.

Is there any reason for why you enable whole-program mode (using -w)? This instructs Soot to compute a call-graph and all, which takes up a lot of memory. For pure instrumentation this should be unnecessary.

Cheers,
Eric
