APP_ID is the id of the application for which logs are shown.

DEVICE is a unique identifier which matches a device name, type, or id
(as returned by the device-list option). e.g. Use "usb" for a usb-connected
device, or "tcp" for an emulator (note: emulator must be running). If not
specified, the first device found is used.

LEVEL is one of {error,warning,info}. For production devices, the default level
is error. To enable more detailed logging, use warning or info.

Examples:

# Display logs for app
${command} com.example.app

# Follow logs for app
${command} -f com.example.app

# List applications on default device
${command} -l

# List applications on usb device
${command} -d usb -l

# List applications on emulator
${command} -d tcp -l

# Set the system log level to "info"
${command} --system-log-level info
