问题 I'm trying to make a USSD call on my app I tried to do this : Intent fastCall = new Intent(Intent.ACTION_CALL); String Num = "*100*200"+ Uri.encode("#"); fastCall.setData(Uri.parse("tel:" + Num)); startActivity(fastCall); but I keep getting an error: Connection problem or invalid MMI code what can I do ? or should I just use ACTION_DIAL ? any idea ? 回答1: No Android does not fully support USSD. Notice that there are no actual USSD APIs. Your dialer may or may not send USSD codes. Really its a

问题 I wonder what is the value of SIM state returned by TelephonyManager.getSimState() when "airplane mode" is turned on? This seems to be not directly specified anywhere in the SDK specification. Actually I need to get SIM operator code (i.e. MCC+MNC) using getSimOperator() method, but JavaDoc states that to use that method: SIM state must be SIM_STATE_READY UPDATE I tested it under emulator and it returns SIM_STATE_UNKNOWN (which is described by javadoc as a "transition between states") after

问题 I am running a B2C outbound Campaign on VicidialNow C.E 1.1 as Asterisk Server / SIP Server . The call is made from server to customer and connected to agents waiting for calls. The agents transfers the call to third party (not a blind transfer). The 3rd party sees the Caller ID of agent. Now, what I want is to display the caller id or the phone number of the customer to the 3rd party. I Googled and searched over SO, found this sendrpid=pai to add on sip.conf file. but this functionality only

问题 I have an app that requires temporary access to the device's SMS. In KitKat and above, this access is only granted to the default SMS app, so I'm using: Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT); intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, getPackageName()); startActivity(intent); This brings up a dialog asking the user if they let my app become the default SMS app. So far so good. Problem is, once my app completes its operation, I have to ask the

问题 I've been puzzling over this one recently, prior to 2.3.5 this seems to work fine (on my colleagues devices). However on mine it now never triggers. I've stripped the code right back and made a very simple test application to see what's going on. Basically the onReceive code doesn't ever appear to trigger, even though adb/logcat does seem to show the register of the BroadcastReveiver does take place. Here's the simple code I've gone for: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns

问题 I'm trying to get the following data: Base station: CellID and RSS (recognition which one is the base station) For all neigbouring stations: CellID and RSS There are various APIs and it looks like i'd have to use different APIs telephonyManager and PhoneStateListener. I'm a littlebit confused, as I think this should be available in one interface. Also I think that it should be possible to poll the CellID of the current Base Station instead of having to listen to State Changes to determine int

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I have been learning more about WebRTC, SIP and PSTN and how they work together especially the ability to receive phone calls in browser. I have spent some time on Twilio's website and I like the way they are able to make you receive a phone call From PSTN to your browser. I want
