This!
Or that!
The transaction is according to the blockexplorer included in block 721,622; NuDroid needs to be past that.
The only thing that might help if you are past 721,622 and have no balance - which I can think of - is to reset the blockchain on your NuDroid.
menu -> settings -> diagnostics -> reset blockchain
That will take a while, but I have no better idea.
Maybe someone else has a better idea. If you don’t want to wait for that, sync the blockchain agin…
Another question: you have made a backup of your NuDroid wallet, right?
If not, please do it and store it safely.
Please don’t lose your funds, because you have no backup!
