How to force android to provide 5 volts to usb port???
If persuasion hasn't worked, you could try threatening it.
You will need a OTG host adapter.
Please don't tell us you want to do something stupid like using your tablet for a power source.
I recommend a large engineer's hammer.
A device like a phone is normally a receiver of +5V on the USB connector, rather than a source of +5V. What makes you think it could be a source?
If it can't be a source, there is no way to force it to be one. Read the USB spec and see that it is not required.
