SetupActivity UI improvements
The password strength bar should be over the password input fields otherwise it will be partially or completely obscured by the soft keyboard (depending on the device). The user should not have to scroll down to see the meter.
Styling! The "Create Account" button has no style at all and does not really fit with the rest. Re-evaluate margins/paddings and consider using the EditText hints rather than TextView headers that makes scrolling necessary for smaller devices.
