I do Android porting mainly for personal use and fun, but as a matter of fact I sometimes find myself struggling to achieve the standards I strive for, as a graduate student still learning his way into the industry and having things to take care of besides coding. If you appreciate my work, please kindly consider donating something equivalent to a beer or two. I will use the donations to support my porting work and studies.
