/system/bin/sh: adb: not found

Question

$ adb shell
# mkdir data/local/tmp/testjars
# exit

That works fine and gives no errors, but when I do:

$ adb push <project_root_folder>/app/build/outputs/apk/app-debug.apk data/local/tmp/testjar/load.apk

I get the error:

/system/bin/sh: adb: not found

What am I missing? How can I fix this?

Answer 1

It looks like you are trying to run adb on the device itself. To push files start adb on the host computer. To disconnect your adb shell session type exit.

You can not run adb push on the android shell. You have to run it on the host computer.

If this is not the case, post the output of echo $PATH.
