rogcat as a library

[tekjar]

Hi. Is rogcat a wrapper over logcat binary or is it a port with more features? I want to write a log shipper for android. My service runs inside android and I need a way to read logs. Can rogcat be used for this purpose?

Hi. rogcat is mainly a wrapper that provides convenience features that the plain logcat doesn't have. It not intended to be used as a library and probably not very portable because it has tons of dependencies. I'm not sure if I fully understand what a log shipper is. Do you want to read the buffers and send it somewhere? This basically running logcat and read it's stdout.

Is your service written in Rust? If yes you can get some inspiration:

If you need to parse the logcat format, have a look at the parser. For calling and capturing locats output see runner.rs.

The individual modules of rogcat are that small that it's not really been worth separating them into crates, but of course this is possible...

Yeah

This basically running logcat and read it's stdout.

Yeah. But I'm not sure of the costs of reading output from logcat vs reading from buffers directly.

Talking to logd directly is probably cheaper. See liblog and logcat. All the headers you need should be part of the NDK.
Otherwise just call logcat and capture. You may want to use the dump flag`.

This seems to be clarified. @tekjar comment if you disagree. :-)

You clarified my question. Thanks :)
