Question

我正在尝试使用此方法阻止Android中的来电，但通过此方法这个例外。我尝试了很多方法，但未能中止来电请帮助这个代码有什么问题。我还在 com.android.internal.telephony.ITelephony 中添加了ITelephony接口。< / p>

检查onReceive()上的通话状态和来电号码。然后使用disconnectPhoneItelephony(Context context)中止来电 -

 public class OutgoingReceiver extends BroadcastReceiver { 

        @Override
        public void onReceive(Context context, Intent intent) {      
                 if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
                            TelephonyManager.EXTRA_STATE_RINGING)) {
                        if (!intent.getAction().equals("android.intent.action.PHONE_STATE") || intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {
                            Toast.makeText(context, "Not phone state", Toast.LENGTH_LONG).show();
                            //return;

                            // Else, try to do some action
                        } else {
                            if (number == null) { //get the incomming call number 
                                number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
             disconnectPhoneItelephony(context); // this is method whick blocks incoming call, this method is provided on the down 
                            }
            }
            }
          }





    // Method to disconnect phone automatically and programmatically
            // Keep this method as it is
            @SuppressWarnings({ "rawtypes", "unchecked" })
            private void disconnectPhoneItelephony(Context context) {
                try {

                    String serviceManagerName = "android.os.ServiceManager";
                    String serviceManagerNativeName = "android.os.ServiceManagerNative";
                    String telephonyName = "com.android.internal.telephony.ITelephony";
                    Class<?> telephonyClass;
                    Class<?> telephonyStubClass;
                    Class<?> serviceManagerClass;
                    Class<?> serviceManagerNativeClass;
                    Method telephonyEndCall;
                    Object telephonyObject;
                    Object serviceManagerObject;
                    telephonyClass = Class.forName(telephonyName);
                    telephonyStubClass = telephonyClass.getClasses()[0];
                    serviceManagerClass = Class.forName(serviceManagerName);
                    serviceManagerNativeClass = Class.forName(serviceManagerNativeName);
                    Method getService = // getDefaults[29];
                            serviceManagerClass.getMethod("getService", String.class);
                    Method tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder.class);
                    Binder tmpBinder = new Binder();
                    tmpBinder.attachInterface(null, "fake");
                    serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
                    IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
                    Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
                    telephonyObject = serviceMethod.invoke(null, retbinder);
                    telephonyEndCall = telephonyClass.getMethod("endCall");
                    telephonyEndCall.invoke(telephonyObject);

                } catch (Exception e) {
                    e.printStackTrace();
                    Log.d("unable", "msg cant disconect call....");

                }


            } 



        }

这是界面 ITelephony.java -

interface ITelephony {

    boolean endCall();

}

并且不要忘记在BroadcastReceiver文件的manifest.xml课程中添加权限和意图过滤器

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

     <receiver
                android:name=".OutgoingReceiver"
                android:enabled="true">
                <intent-filter android:priority="9999">
                    <action android:name="android.intent.action.PHONE_STATE" />
                    <action android:name="android.intent.action.NEW_OUTGOING_CALL" 
<action android:name="android.intent.action.RESPOND_VIA_MESSAGE"/>

                </intent-filter>
            </receiver>
