Is there an API to control charging in Android OS?

If i make the connection shown above, the Walkman will be in power supply mode and cannot be charged.
The DAC to which the miniB is connected has a power supply and does not require power supply from the Walkman.

After the connection with the DAC connecting the miniB is established, I want to be able to charge the Walkman from the charger connected to Type A under the control of the software.

    It seems that it can not be done unless Android is rooted.
    It turned out that rooting is not covered by the manufacturer's warranty and cannot be commercialized.

    How about this?
