Will it work for android os?

[dkumar1987]

If i compile this as .so then it'll work in ip packet parsing?

[mfontanini]

Good question. I guess it should, since android OS is Linux based. Of course you'd need to either compile inside an android OS, or cross-compile, but I guess it should work.

The answer is yes, but there are a couple of things that need to be done.
I've been meaning to push my changes upstream, but I'm still using libtins 2.0

1. Add ifaddrs, because it is missing in the android NDK (or was when I last checked in jan 2014).
   https://github.com/kmackay/android-ifaddrs
   I use cmake to only include/compile that folder when building for android.
2. Add libpcap (or at least the header files). Should be trivial.
3. fix a compiler error in src/network_interface.cpp

Will libpcap work for non rooted devices in android?

[einarjon]

It should be enough to add only pcap.h and pcap/bpf.h include files. That are the only includes that libtins is using*, and you don't actually need the libpcap.so binaries.

Otherwise you need to build and install the library. I'm not sure if you can do that on a non-rooted android.
*) At least for LibTins 2,0 without 802.11/WPA2 support.

[dkumar1987]

Thanks, I try.

[mfontanini]

I just added those fixes to the code, so you shouldn't need to touch anything besides including the ifaddrs files.

Thanks @einarjon for the instructions! I'm going to add some tutorial on the website on how to compile it on android soon based on them.

Closing since it should compile on android now.

[nbroeking]

I know this issue is closed but I figured I would add another comment because I know many people will be frustrated with the information given. It will compile for android but it wont run. Android does not have the proper drivers installed to do monitor mode on their devices and thus you need to get drivers that can do that work for you. You should look into the work being done on bcmon.

But instead of monitoring can I craft and send packets in Android and iOS?

[einarjon]

We used this to modify packets sent between Linux and Android years ago. It works the same way on both OSes. I have no iOS experience, but it should not be any different. Best regards, Einar Jón

Are the modifications still needed?

https://github.com/kmackay/android-ifaddrs

does not exists anymore

[ilyasKerbal]

@lattice0 any updates?

[lattice0]

I made a PR and now it works on Android

Thanks @lattice0 #471
Can you share the steps to setup?

[lattice0]

I don't have the code right now but you should be able to do it with add_subdirectory(...) To the libtins directory, but following android's cmake way of calling a lib using CMakeLists.txt

For some reason I get the following error:

1. Could NOT find PCAP (missing: PCAP_LIBRARY PCAP_INCLUDE_DIR)

@lattice0

[lattice0]

You can disable https://github.com/mfontanini/libtins/blob/master/CMakeLists.txt#L60

maybe unset(LIBTINS_ENABLE_PCAP) or set(LIBTINS_ENABLE_PCAP OFF) before add_subdirectory, I don't remember exactly

[ilyasKerbal]

Thank you so much @lattice0 I just solved the problem. Your guidance helped a lot.
