Android Studio: Reject Incoming Call

Sumber: http://stackoverflow.com/questions/3809588/how-to-reject-incoming-call-programatically-in-android?rq=1

Let us implement this solution in 3 steps :

a. Define this class or receiver :

This is your main class :

package com.sample; import java.lang.reflect.Method;

import android.app.Activity; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.content.SharedPreferences; import android.os.Bundle; import android.preference.PreferenceManager; import android.telephony.TelephonyManager; import android.util.Log; import android.widget.Toast;

import com.android.internal.telephony.*;

public class main extends BroadcastReceiver { private static final String TAG = null; String incommingNumber; String incno1= "9916090941";

public void onReceive(Context context, Intent intent) {

   Bundle bundle = intent.getExtras();

   if(null == bundle)
           return;
   SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);       
   try {
       // Java reflection to gain access to TelephonyManager's
       // ITelephony getter
       TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
       Log.v(TAG, "Get getTeleService...");
       Class c = Class.forName(tm.getClass().getName());
       Method m = c.getDeclaredMethod("getITelephony");
       m.setAccessible(true);
       com.android.internal.telephony.ITelephony telephonyService = (ITelephony) m.invoke(tm);  
       Bundle b = intent.getExtras();
       incommingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
       Log.v(TAG,incommingNumber );
       Log.v(TAG,incno1 );
       if ( incommingNumber.equals(incno1) )
       {
            telephonyService = (ITelephony) m.invoke(tm);
              telephonyService.silenceRinger();
       telephonyService.endCall();
       Log.v(TAG,"BYE BYE BYE" );
       }
       else{

       telephonyService.answerRingingCall();
       Log.v(TAG,"HELLO HELLO HELLO" );
       }

   } catch (Exception e) {
       e.printStackTrace();
       Log.e(TAG,
               "FATAL ERROR: could not connect to telephony subsystem");
       Log.e(TAG, "Exception object: " + e);
   }

   }

}

b. Manifest file :

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"

     package="com.sample"
     android:versionCode="1"
     android:versionName="1.0">
   <application android:icon="@drawable/icon" android:label="@string/app_name">
      <receiver  android:name=".main">
           <intent-filter  android:priority="100" >
               <action android:name="android.intent.action.PHONE_STATE" />
           </intent-filter>
       </receiver>

   </application>
   <uses-sdk android:minSdkVersion="7" />
<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" />

</manifest>

c . Define telephone aidl , under com.android.internal.telephony

package com.android.internal.telephony;

 interface ITelephony { 
   boolean endCall();

   void answerRingingCall();

   void silenceRinger();
}

mh: Worked for me only in emulator, not on real devices... All devices above android 2.3 require root permission or installation as a system app to be able to use the permission android.permission.MODIFY_PHONE_STATE.
