A few lines to add "adb exec-out" support.

[T2hhbmEK]

from adb_shell.adb_device import AdbDeviceTcp as _AdbDeviceTcp, constants, exceptions

class AdbDeviceTcp(_AdbDeviceTcp):
    def exec(
        self,
        command,
        transport_timeout_s=None,
        read_timeout_s=constants.DEFAULT_READ_TIMEOUT_S,
        timeout_s=None,
        decode=True,
    ):
        if not self.available:
            raise exceptions.AdbConnectionError(
                "ADB command not sent because a connection to the device has not been established.  (Did you call `AdbDevice.connect()`?)"
            )

        return self._service(
            b"exec",  # send exec instead of shell
            command.encode("utf8"),
            transport_timeout_s,
            read_timeout_s,
            timeout_s,
            decode,
        )

I'd like to see this feature soon. XD. Sorry for not able to submit a PR myself.

Could you please post a log from an exec command with the log level set to debug. That way I can add a unit test for this function.

[T2hhbmEK]

Sorry, I am not familiar with adb debugging. I need more detailed information on how to get the log so I can help.

[JeffLIrion]

Python logs, not ADB logs. This should work:

import logging

logging.getLogger("adb_shell.adb_device").setLevel(logging.DEBUG)
logging.getLogger("adb_device").setLevel(logging.DEBUG)

[T2hhbmEK]

import logging
from adb_shell.adb_device import AdbDeviceTcp

logging.basicConfig(level=logging.INFO)
logging.getLogger("adb_shell.adb_device").setLevel(logging.DEBUG)
logging.getLogger("adb_device").setLevel(logging.DEBUG)
device = AdbDeviceTcp("127.0.0.1", 7555)
try:
    device.connect()
    r = device._service(b"exec", "echo TEST".encode("utf8"))
    print(r)
finally:
    device.close()

The difference between exec and shell is that shell will turn \n into \r\n.

[JeffLIrion]

Thanks, I can work with that.

From https://www.linux-magazine.com/Issues/2017/195/Ask-Klaus:

adb exec-out "<command>"

Run command on Android and capture its unfiltered binary output (stdout)

I think I'll keep the default value of decode=true for this function, although it seems like this will produce the same results as shell, aside from the \n vs. \r\n difference that you pointed out.
