@marcbonnici please take a look! |
This patch fixes following issues: * Starting from Android 11 it is not possible to use Runtime.exec to execute commands that require shell permissions like `am start`. * Engineering Android versions has su that doesn't support -c argument.

We tend to try and avoid hardcoding paths to support different configurations if possible.
Currently we have the default self.executables_directory set to /data/local/tmp/bin. I'm wondering if these directories would share the same requirements which we could also make use of here rather than setting this parameter in two locations?
If not perhaps this be a workload Parameter with a default so a user can understand the requirements for the directory and optionally change this for their system if required?

The main requirement for assert_directory for applaunch workload is a ability to create readonly files there and looks like executables_directory in general doesn't require it. But adding a new parameter for applauch workload with a default value is a good idea, thank you!

Thinking about this a bit more, do other workloads that require root work on these engineering versions if they are relying on the su -c format?
In devlib we try to detect [1] which su command (su -c or 'echo {} | su) [2] we should use for a device so I'm wondering if it would be beneficial to move this check to the common code and then we can query it from here?

Yes, I think moving this check to devlib is a good idea, thank you! I will create a PR for it.
