telephonymanager

I am planning to create an Android App that will automate sending a users response to a USSD Menu. At a click of a button, the app will send the initial code, followed by the rest of the menu inputs. For example, the initial number is *143#, followed by 1, 1, 1, and a user PIN. I'd like to be able to automate that sequence of inputs so that the user won't have to input it on their own. I know that in Android Oreo, they implemented a USSD Callback using the TelephonyManager, where the Android App can send a USSD Request, and then read the response given. I am currently exploring that option and

I want to detect outgoing call in android application . Actually I can detect outgoing calls but it is also working for incoming too and I don't want that. I need it to work only for outgoing. here is my code.... boolean ringing = false; boolean offhook = false; public void onCallStateChanged(int state, String incomingNumber) { switch (state) { case TelephonyManager.CALL_STATE_IDLE: if((!ringing)&& offhook){ ///incomming call } break; case TelephonyManager.CALL_STATE_RINGING: callerPhoneNumber = incomingNumber; Log.d(TAG, "RINGING"); ringing = true; offhook = false; break; case

I am working on app where i want to end outgoing call. this is the main class import android.app.Activity; import android.content.ActivityNotFoundException; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.util.Log; public class phonecalls extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); call(); } private void call() { try { Intent callIntent = new Intent(Intent.ACTION_CALL); callIntent.setData(Uri

Can anyone say why the documentation for the getNetworkOperator function of TelephonyManager states that this can return unreliable result for CDMA ? getNetworkOperator documentation Availability: Only when user is registered to a network. Result may be unreliable on CDMA networks (use getPhoneType() to determine if on a CDMA network). What kind of results are you getting when calling this method on a CDMA device ? and if it's not reliable, How can I get the MCC for a CDMA device ? I know this is an old question, but maybe is useful to other people. I don't know what returns from some CDMA

I am having an android application that fetches information of cell towers. I use this getAllCellInfo() to fetch info of a primary cell and neighbour cells. I included the ACCESS_COARSE_LOCATION permission to manifest.xml and make a request for the permission in runtime. It works in other phones but in Huawei Honor 7, the function returns an empty list. My code: Catlog: I have checked other people questions: getAllCellInfo returns null in android 4.2.1 and Android getAllCellInfo() returns null . From a question, I thought for Huawei phones, they don't support getAllCellInfo() until I installed
