android - WiFi direct: how often to call peer discovery? -


i developing p2p app , following tutorial here , while testing on 2 phones wandering when have initiate peer discovery?

only once when app started, periodically or every time in onresume?

i'm asking because times when try show list of peers can't find any. i know cause of , actualy peer discovery , doing.

i start discovery through listeners registered in app every 'x' seconds , yes, want initiate discovery onresume() well. also, presume leveraging broadcast intents determine state change.

i can't however, clarify on internals of p2p discovery discovery fail because network busy or due internal error or because device doesn't support p2p mentioned here.
