Android: Support PasswordMaskDelay

Browse Source 
It is only set if the "Show passwords" option in Android's security
settings is enabled, the value is not updated at runtime as this option
isn't likely to be changed frequently, if at all.
The value of 1.5s is hardcoded in Android's PasswordTransformationMethod.
