There is no Android app for FoE, therefore I think we have to wait also for a app at elvenar
As FoE and also Elvenar are FLASH-BASED the problem is less that there Android apps don't exist , it's more the problem that newer Android versions don't support (Adobe-)Flash because there is no 'agreement' ( $ + $ + $ ...) between Google and Adobe, like an $$$- agreement between Apple and Adobe ...
If you want to use Adobe-Flash on such devices you need to install the support Adobe-Flash by your own - for example buy installing an Android-browser which supports Adobe-Flash (eg. Puffin or others ...)
The good news are, that this might work, the bad news are that this isn't free: normally you have to pay for the Adobe-Flash-Support-Extension for Android.
It seems that Android system providers (like Google,
CyanogenModetc.) will go their 'own way' without Adobe-Flash also in the future, and almost all, with the exception of pure flash-based 'applications', is working and will work.
So the question 'when' Android apps of FoE, Elvenar etc. will come, can be answered with: they will come when games are programmed which are not flash-based ...
