안드로이드 - 전화 수신 거부

안드로이드 - 전화 수신 거부 

Step 1:
Create Broadcast receiver class for incoming call

package com.javaorigin.android.sample;

import java.lang.reflect.Method;

import com.android.internal.telephony.ITelephony;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent
import android.telephony.TelephonyManager;
import android.util.Log;

public class PhoneCallReceiver extends BroadcastReceiver {
 Context context = null;
 private static final String TAG = "Phone call";
 private ITelephony telephonyService;

 @Override
 public void onReceive(Context context, Intent intent) {
  Log.v(TAG, "Receving....");
  TelephonyManager telephony = (TelephonyManager) 
  context.getSystemService(Context.TELEPHONY_SERVICE);  
  try {
   Class c = Class.forName(telephony.getClass().getName());
   Method m = c.getDeclaredMethod("getITelephony");
   m.setAccessible(true);
   telephonyService = (ITelephony) m.invoke(telephony);
   telephonyService.silenceRinger();
   telephonyService.endCall();
  } catch (Exception e) {
   e.printStackTrace();
  }
  
 }

 
}

Step 2:
Create IDL interface for getting core Telephony service
package name must be com.android.internal.telephony

FileName : ITelephony.aidl

  package com.android.internal.telephony;

  interface ITelephony {

   
    boolean endCall();

  
    void answerRingingCall();

   
    void silenceRinger();

  }

Step 3:
AndroidManifest.xml configuration

  <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.javaorigin.android.sample"
      android:versionCode="1"
      android:versionName="1.0">  
    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <receiver  android:name=".PhoneCallReceiver">
            <intent-filter  android:priority="100" >
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>

    </application>
    <uses-sdk android:minSdkVersion="5" />
    <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <uses-sdk android:minSdkVersion="8" />

</manifest>
