Solution 1
you have added ITelephony.AIDL file in your project? and if you have added then your package name must be com/android/internal/telephony/ITelephony.AIDL:
for more information Blocking Incoming call. download AIDL file from here
Solution 2
You can use reflection to call methods on the ITelephony object thus avoiding the need to specify the type and add the AIDL file. For instance, ending a call:
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
Object telephonyService = m.invoke(tm);
Class<?> telephonyServiceClass = Class.forName(telephonyService.getClass().getName());
Method endCallMethod = telephonyServiceClass.getDeclaredMethod("endCall");
endCallMethod.invoke(telephonyService);

void answerRingingCall();
void silenceRinger();
}

Prashant Kadam almost 2 years
i am creating simple call filter application which restrict unwanted calls. i use following code to restrict call but i am unable to resole problem of this line in below code " com.android.internal.telephony.ITelephony telephonyService = (ITelephony) m.invoke(tm); " it show the error message com.android.internal.telephony cannot be resolved to a type in android how to resolve this error .
public class CallBlockReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub } private void getTeleService(Context context) { TelephonyManager tm = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE); try { // Java reflection to gain access to TelephonyManager's // ITelephony getter Log.v("", "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); } catch (Exception e) { e.printStackTrace(); Log.e("", "FATAL ERROR: could not connect to telephony subsystem"); Log.e("", "Exception object: " + e); } } }Please help me .

ρяσѕρєя K about 12 yearsPrashant, make com/android/internal/telephony folder structure inside src folder and put aidl file in telephony folder -
Ankit Aggarwal almost 8 yearsThanks a lot! Brilliant answer!
