the original code is here
import subprocess as sp
cmd = ["adb","push","file","/mnt/sdcard/file"]
mysp = sp.popen(cmd, env={'ADB_TRACE':'adb'}, stdout=sp.PIPE, stderr=sp.PIPE)
stdout,stderr = mysp.communicate()
if mysp.returncode != 0:
print stderr
else:
print stdout
it works fine without env={'ADB_TRACE':'adb'}.
exec any command about adb with the env variable, i got an error:
ADB server didn't ACK
* failed to start daemon *
error: cannot connect to daemon
it seems not to work after kill the adb server
the whole output is here
OS:win7
I suspect adb also needs other environment variables (like $HOME).
You should clone your existing environment and add ADB_TRACE to it.
import os
new_env = os.environ.copy()
new_env['ADB_TRACE'] = 'adb'
# sp.popen()
From the docs:
If env is not None, it must be a mapping that defines the environment variables
for the new process; these are used instead of inheriting the current process’
environment, which is the default behavior.
Edit:
It seems, it's not about the envoronment itself.
Rather the adb server is broken if ADB_TRACE is set.
Try to start the server beforehand in an environment without ADB_TRACE.
