Question

我一直在开发一款可以作为闹钟系统的应用程序，当一个人开始漫步时会发送该应用程序。在我当前的代码中，我设置为在按下sos按钮时发送文本。我使用的是23以上的API，但我确实拥有正确的权限。我也尝试连接telnet到我的模拟器，看看是不是问题，但它不是。

以下是我在oncreate方法中检查权限的代码

   //Checking to see if we asked for location permission
    if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)!= PackageManager.PERMISSION_GRANTED){

        //If we dont have permission we need to ask for it
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);

    }else {

        //We already have permission so we listen to the location
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
    }

    //Checking to see if we asked for sens sms permission
    if(ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS)!= PackageManager.PERMISSION_GRANTED){

        //If we dont have permission we need to ask for it
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SEND_SMS}, 2);

    }else {

        //We already have permission so get smsManager
        Log.i("Permission", "Alreadly Granted");
    }

这是我的onPermissionsRequested代码

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        if(grantResults.length > 0){

            for(int i = 0; i < grantResults.length; i++){

                if(requestCode == 1 && grantResults[i] == PackageManager.PERMISSION_GRANTED){

                    //Checking to see if we asked for location permission
                    if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)== PackageManager.PERMISSION_GRANTED){

                        //listening to the users location
                        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

                    }

                }

                if(requestCode == 2 && grantResults[i] == PackageManager.PERMISSION_GRANTED){

                    //Checking to see if we asked for location permission
                    if (ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED) {

                        Log.i("Permission", "PermissionGranted");
                    }

                }
            }
        }

    }

最后，这是从按下按钮

发送文本时的代码

sos = (Button) findViewById(R.id.sosButton);
        sos.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage(phoneNumber, null, "Safe Stroll Test", null, null);

            }
        });

我也尝试在onClick中检查权限，并获得相同的结果。我的问题是因为我正在使用模拟器还是我错过了我需要从smsManager API实现的东西？

SEND_SMS没有崩溃或从模拟器发送
