I believe the above are lite wallets, no staking.
Navcoin & Evergreen are working on some , release date unknown.
However
Pretty much anyone that pays for one can have one.
VegasGuy offers a service where they will build you a lite android wallet that does not stake , or a full android wallet that can stake.

Warning : Running a Full Staking Android Wallet has many issues.
1. It has to download the entire blockchain
2. Unless connected to free wifi it will eat up the minutes of your cellphone plan
3. Due to increased processor usage causing more heat it may shorten the life of the android
4. It will probably be necessary to keep it connected to an ac adapter to keep from draining the battery down when staking.
Simpler Solution is to setup a VPS , and use your Phone to remote in and control your VPS if you want a staking system or just remote control your Home PC.
thank for this, since staking on android will require me to download the whole blockchain and it will shorten my phone's life, i think i shouldn't do staking on phone. thanks again
