Description

@Jiangrong-W

Hello, When I use JuCify to run the benchmark app delegation_proxy.apk, using following command:
java -jar JuCify-0.1-jar-with-dependencies.jar -a delegation_proxy.apk -b before.txt -c result.txt -p ~/Library/Android/sdk/platforms -e cg.dot -ta

it shows results:

JuCify v0.1 started on Wed Oct 26 11:01:23 CST 2022

[] Processing: lu.uni.trux.delegation_proxy

Results:

  • App name: delegation_proxy

  • Taint Analysis elapsed time: 0
  • Number of nodes before Jucify: 11
  • Number of nodes after Jucify: 11

  • Number of edges after Jucify: 10
  • Number new Java-to-Native Call-Graph edges: 0
  • Number new Native-to-Java Call-Graph edges: 0
  • Number new Call-Graph reachable nodes: 0
  • Number new Call-Graph reachable nodes Java: 0
  • Number new Call-Graph reachable nodes Native: 0
  • Number new Call-Graph edges: 0
  • Has flow through native: No

there is no flow from bytecode to native, Did I do something wrong?
