Question: How to stream from a given inputStream into a root-command outputStream? about libsuperuser HOT 7 CLOSED

There isn't one, currently.

from libsuperuser.

I didn't know it's even possible. It seems it can be useful though:

http://www.longluo.me/blog/2016/10/01/Android-Develop-Tools-ADB-Manual/

pm install-write: write a package into existing session; path may
be '-' to read from stdin
-S: size in bytes of package, required for stdin

That's probably what the repository is using.
Weird is that I don't see all commands on official docs though:
https://developer.android.com/studio/command-line/adb

Anyway, can you please add it somehow? Or maybe think of a workaround for now?

from libsuperuser.

This would be very tricky to get right for an interactive shell, due to all the edge-cases on how programs handle STDIN., and only very rarely used. If you must do this exact thing, use the sample code you provided yourself.

Think of a work-around? For this specific case there are several. For this install-write command you could just use the source paths of the APKs in the command directly instead of reading the APK into a stream and then writing it to another, for example. Or PIPE the commands on the shell level rather than the Java level.

If the data isn't coming from disk, you can cache it on disk and pass the path, or maybe even create a fifo file you write to from Java and read from in the shell.

Suppose I got root, though, this could still work later, no?
It won't ask the user for root again, right?

from libsuperuser.

That depends on the root management app. They can be set to ask for every "su" request, in which case you'd be asked again. Mostly the default is ask once for any UID and then keep it granted, so you'd only see it once regardless of which method you use to execute root commands.

from libsuperuser.

Thought so.
Would you please reconsider adding this though? Even as a stand-alone function?
I think you got all the other cases covered, except this one.

Like @AndroidDeveloperLB, I'm here after looking at the same code in SAI and wondering if it's possible with libsuperuser. While it's not a must-have feature, but it will definitely make this library complete.
