is there an j2me phone state listener similar to android's PhoneStateListener

I'm going to develop app that will need to detect the caller number and be able to drop the call. I've got several various j2ee midp2 enabled phones I want to use for this, but I can't find j2me API that is able to provide me the caller number and/or manage the call state (drop it).

On Android there is PhoneStateListener, so app can listen to incoming calls and deals with it.

Since the application is not for resale / distribution (I am not bound to mobile phones but only to the GSM network) I can use also some reasonably priced industrial-grade solution too.

So the Q is: is there any possibility to detect caller details in j2me or I just hav开发者_StackOverflow中文版e to trash all my available Nokia phones and buy some low-end Android stuff instead?

Unfortunately this functionality is not available in Java ME. Only you can make call from within an application. You can't access call registry.

currently, low-end Android stuff seems like the way to go.

• There is JavaME API specification for stuff like that (JSR 253 Mobile Telephony) but I am not aware of any real phones that support it
  

  The Mobile Telephony API allows java applications to access call-related functionality such as:

  • Initiate voice and emergency calls
  • Receive/accept an incoming call
  • Control and end an existing call
  • Receive event notifications of call state changes
  • Receive event notifications of network state changes (e.g. roaming to a different network)
  • Access network information such as Network ID and "Network Selection Modes"
  • Use supplementary services such as multiparty calls, and call forwarding
  • Get status information about supplementary services
  • Activate/deactivate supplementary services
  • Send/receive Unstructured Supplementary Service Data
  • Manage call-related phone and user parameters such as "Phone Identity Presentation Restriction" or "User Group"
