telephonymanager

问题 I've very newly gotten into Android development, and decided that my first conquest on this fresh field would be to grasp how the phone reacted to incoming calls. A little googling later led me to http://www.compiletimeerror.com/2013/08/android-call-state-listener-example.html#.Vi3Ren4vfwM (so my code shares a striking resemblance to his/hers). My main (and only) activity looks like this: import android.app.Activity; import android.content.Context; import android.os.Bundle; import android

问题 I'm doing a program to send the CallLog to a Server, I created a Service that makes a poll of the telephone status with the following method. This method is called onCreate. private void pollForCallStatus() { timer.scheduleAtFixedRate(new TimerTask() { @Override public void run() { Log.d("Poll", Integer.toString(telephonyManager.getCallState())); switch (telephonyManager.getCallState()){ case TelephonyManager.CALL_STATE_RINGING: Log.d("CallService", "ringing"); break; case TelephonyManager

问题 I need to get the number that I am calling from my Android device programmatically. What I'm doing now is the following: I listen for android.intent.action.PHONE_STATE being broadcasted which means that either I am being called or am calling (or receiving an SMS etc). In a BroadcastReceiver I retrieve the extra incoming_number from the intent. Sadly I cannot get the number which is being called if I initiate the call though. How can I do this? 回答1: You need to use the Intent android.intent

问题 I want to develop an app which tracks the sent/received SMSs. I mean, when a user sends a message from its device, the message detail should be saved to a table provided by me. Similarly, when the device receives any SMS, then that also should be saved into a table provided by me. Note that the user uses the default message application of Android to send message. I mean I am not integrating my application with the default message application. I just need to keep track of all messages sent

问题 I know that using TelephonyManager we can get MNC and MCC of our network provider, TelephonyManager tel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); String networkOperator = tel.getNetworkOperator(); if (networkOperator != null) { int mcc = Integer.parseInt(networkOperator.substring(0, 3)); int mnc = Integer.parseInt(networkOperator.substring(3)); } But I was able to get MNC and MCC data of only primary sim. I would like to know is there a way to fetch mnc,mcc,lac and

问题 I'm writing an app that runs on background during a telephone conversation and logs the coordinates to a file after the conversation has end,I know Android telephony API can detect a call manual disconnect by user*(correct me,if I'm wrong)*, But what I want is to know whether the service disconnection have caused due to call drop,is there a way or an API I can use to achieve this, All what I need is to programmatically differentiate a disconnected call and a dropped call. Please help. 回答1:

问题 I am trying to send a broadcast to simulate an incoming call. I added the permission in AndroidManifest.xml file, <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> When I try to run the program, the phone reboots.(Emulator too). Intent intent = new Intent(); intent.setAction("android.intent.action.PHONE_STATE"); intent.putExtra(TelephonyManager.EXTRA_STATE, TelephonyManager.CALL_STATE_RINGING); intent.putExtra("EXTRA_INCOMING_NUMBER", "923982398"); intent

问题 A few people over the past decade have asked similar questions but none have ANY answers. I need to write an android app that collects and stores RSRP, RSRQ, CINR, and Cell ID. The answers need to be as accurate as the phones hardware allows (I am testing on Samsung Galaxy S5) because I need to do post processing statistics with those values. Does anyone know how to use telephonyManager or CellSignalStrengthLte to get RSRP? Or is there another, perhaps better way to get RSRP? So far the best
