As you provided the source, I investigated a "Force Close" I obtained right after login while obtaining user info:

In Profile.java, displayInfo() method, line 43, Double.valueOf can't parse the string "1.82E-5" of my Globals.profitToday (Yes I know so much gain !).

This buggy value appears to be returned by your API (Captured this at runtime on Network.java, line 98):

{"username":"twix","balance":"0.00003246","spent_total":"0.01424222","won_total":"0.00476164","deposits_total":"0.00000000","withdrawals_total":"0.00000000","profit":-0.00948058,"profit_today":1.82e-5}
