在Android异常来电阻止

Question

我想阻止Android使用此方法的传入呼叫，但通过 这种异常。我已经尝试了这么多的方法，但未能中止来电，请帮助这个代码的问题。我还在com.android.internal.telephony.ITelephony中添加了ITelephony接口。

代码

String Messageofenemy; 
String Blckno; 

public OutgoingReceiver() {

@Override 
public void onReceive(Context context, Intent intent) { 

    try { 


     if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) { 


      Intent i = new Intent(context, MyService.class); 
      context.startService(i); 
      return;

检查通话状态和onReceive()呼入号码。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...."); 

       } 


      } 



     } 

这里是接口ITelephony.java -

interface ITelephony { 

    boolean endCall(); 

} 

不要忘记对您的BroadcastReceiver类上的manifest.xml文件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>
