Thanks for writing.
The legend view is completely independent from the android layout and can be positioned anywhere. You can put both the chart and the legend in the same parent panel of your choice, then you can align the legend to the bottom left and make the chart fill the whole parent panel.
To render labels with a white outline on the doughnut chart you have to inherit from PieSeriesLabelRenderer and override the renderLabelMethod.
If you need further support, please consider purchasing the controls.
