How to communicate between native processes

[vick.s]

Hello seniors,
i have two processes running in my native code, i need a
communication mechanism between them. I learnt about d-bus and tried
to implement, but it seems ndk does not support d-bus.
Is there any other processes i can use for IPC? If somebody can
provide any materials or tutorial links, it will be very helpful.

Thanks

Hi Vick,

Here is a quick tutorial on Unix IPC:

http://beej.us/guide/bgipc/output/html/multipage/index.html

In order to be safe, I would suggest the following two options first:

1. Plain TCP/IP socket communication between your applications through the loop-back device.  Since networking is officially supported by the NDK, we know that this interfaces will survive.

2. Using AIDL through JNI. Which is probably the safest way.

Best regards,

I would recommend against this, as the application will have to have
internet permission even for local loop back, and users will wonder
why if it is not by nature a networked application.

Using a unix domain socket avoids this. (Android's linux kernel is
modified to place restrictions on the AF_INET family, but not the
AF_UNIX family)
