Pin Progress For Android:

Introduction:

• Custom indicator that could show all of the information in a tiny footprint.

• The color indicates whether it's downloaded (blue) or not (gray). The appearance of the pin indicates whether the download is permanent (white, upright) or temporary (gray, diagonal). And when state is in the process of changing, progress is indicated by a moving pie chart.
• We can use this pie chart to show our progress instead of progress bar, it takes minimum space to show & flexibility to appear on top of the downloading content.
