Hello Shabna M,
The Android BSP images are only able to boot with Linux as doman 0, which is how the Xen for Android Project works.

Technically speaking you could boot Android in Dom0, provided that you make the necessary adjustments, which are not trivial (as you can see by the Xen documentation). We do not have documents that could guide you trough these changes as this is not a supported configuration.
My apologies for the inconvenience.
Regards,
