android – No such method getITelephony to disconnect Call

Posted by: admin May 14, 2020 Leave a comment

Questions:

i want to disconnect outgoing call in ICS.

My issue is first of all I am not getting the broadcast in IC` in Gingerbread it is working fine and blocking the calls but in ICS its not Broadcasting.

for BroadCast I created a service and in that I am getting BroadCast of PHONE_STATE in ICS also but when i try to disconnect call I am getting error of

NO such method name 'getITelephony'

in ICS call is not disconnecting.

I am using following code to disconnect call using the BroadCast…

try{
       TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
       Class c = Class.forName(manager.getClass().getName());
       Method m = c.getDeclaredMethod("getITelephony");
       m.setAccessible(true);
       ITelephony telephony = (ITelephony)m.invoke(manager);
       telephony.endCall();
  } catch(Exception e){
       Log.d("",e.getMessage());
  }

AndroidMaifest.xml

PhonecallStateBroadcastReceiver.java

with packgename of package com.android.internal.telephony;

ITelephony.aidl

interface ITelephony 
{
    boolean endCall();
    void answerRingingCall();
    void silenceRinger();
}
How to&Answers:

1) Download this class : ITelephony

2) Add this class.java in your project in package: com.android.internal.telephony

3) Add this permission in your manifest :

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />

And this receiver in application balise :

<receiver android:name=".CallReceiver" >
   <intent-filter>
     <action android:name="android.intent.action.PHONE_STATE" />
   </intent-filter>
</receiver>

4) Create CallReceiver class :

@Override
public void onReceive(Context context, Intent intent) {
    ITelephony telephonyService = getTeleService(context);
    if(telephonyService!=null) {
        try {
            String numberCall = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
            Log.i("TAG", "CALL NUM: " + numberCall);
            if(numberCall.equals(TEST_NUMBER)) {
                telephonyService.endCall();
                Toast.makeText(context, "END CALL: " + numberCall, Toast.LENGTH_LONG).show();
                Log.i("TAG", "END CALL");
            } else {
                Log.i("TAG", "ACCEPT CALL");
            }
        } catch (Exception e) {
            e.printStackTrace();
            Log.i("TAG", "CATCH CALL");
        }
    }
}

private ITelephony getTeleService(Context context) {
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    try {
        Method m = Class.forName(tm.getClass().getName()).getDeclaredMethod("getITelephony");
        m.setAccessible(true);
        return (ITelephony) m.invoke(tm);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

Answer:

use of reflection to get access to “getITelephony” won’t work in Android 2.3+

Reference:

How do you programmatically end a call on 2.3+?

Answer:

Class c = Class.forName(“android.telephony.TelephonyManager”); this will solve your problem for Android 2.3+
