java – 在奥利奥,我无法获得传出号码

我正在尝试获取传出号码,但在oreo之前,代码工作得非常好,但在使用oreo代码的设备中无效.

     public class IncomingbroadCastReceiver extends broadcastReceiver {
        Context context;
        WhatsAppContacts requiredContact;
        List<String> messages = new ArrayList<>();
        String callerName="";
        Realm realm;
        String outgoingNumber = "";

        @Override
        public void onReceive(final Context context, final Intent intent) {
            Log.d("Search","onReceive");
            this.context = context;
            realm = Realm.getDefaultInstance();
            TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
                telephony.listen(new PhonestateListener(){
                    @Override
                    public void onCallStateChanged(int state, String incomingNumber) {
                        super.onCallStateChanged(state, incomingNumber);
                        Log.d("Search","above Ringing"+state);
                        if(state ==  TelephonyManager.CALL_STATE_RINGING){
                            SharedPreferences sharedPreferences = PreferenceManager
                                    .getDefaultSharedPreferences(context);
                            SharedPreferences.Editor editor = sharedPreferences.edit();
                            editor.putString("number", incomingNumber);
                            Log.d("Ringing", incomingNumber);
                            editor.apply();
                            Log.d("Search","inside call state changed");
                            initialiseAndStartService();
                        }
                        else if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")){
                            //Outgoing call
                                String number=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
                                Log.i("tag","Outgoing number : "+number);
                                if(number!=null){
                                    SharedPreferences sharedPreferences = PreferenceManager
                                            .getDefaultSharedPreferences(context);
                                    SharedPreferences.Editor editor = sharedPreferences.edit();
                                    editor.putString("number", number);
                                    editor.apply();
                                    Log.d("Search","inside call state changed");
                                    initialiseAndStartService();

                                }
                        }
                    }
                },PhonestateListener.LISTEN_CALL_STATE);

        }

}

在奥利奥之前的版本中,它的工作完全正常.但在奥利奥无法获得传出号码.

解决方法:

奥利奥有一个限制.您无法在清单中注册隐式广播,而NEW_OUTGOING_CALL是隐式广播.当您的应用程序处于活动状态且用户正在与其进行交互时,您才能进行该广播工作.
