与服务一起使用时使用 SMS 管理器时出现问题

Question

我是 android 的新手。我正在创建一个 android 服务，它检索当前位置并将其作为消息发送到特定号码。我几乎已经实现了，但是当我使用 SMSManager 发送检索到的位置值的消息时，应用程序崩溃了（我已经评论了附件中的代码）。我已经完成了检索当前位置并将其显示在 EditText 上的步骤。我已经包含了所有 permissions.Kindly 帮助我解决发送接收到的意图值的消息的问题。我已经包含了 MainActivity 和 BroadcastService

的代码

int count=1;

@Override
protected void onResume() {
    super.onResume();
    if(broadcastReceiver == null){
        broadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {

                textView.setText("\n" +intent.getExtras().get("coordinates"));

               String loc = textView.getText().toString();

                    /*
                    SmsManager sms = SmsManager.getDefault();
                    sms.sendTextMessage("7448958358", null, loc, null, null);
                    */

            }
        };
    }
    registerReceiver(broadcastReceiver,new IntentFilter("location_update"));
}

@Override
protected void onDestroy() {
    super.onDestroy();
    if(broadcastReceiver != null){
        unregisterReceiver(broadcastReceiver);
    }
}
private void sendSMS(String phoneNumber, String message) {
    Toast.makeText(this, "sending", Toast.LENGTH_SHORT).show();
    }
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn_start = (Button) findViewById(R.id.button);
    btn_stop = (Button) findViewById(R.id.button2);
    textView = (TextView) findViewById(R.id.textView);
    if(!runtime_permissions())
    {
        enable_buttons();
    }
}

private void enable_buttons() {

    btn_start.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent i =new Intent(getApplicationContext(),BroadcastService.class);
            startService(i);
        }
    });

    btn_stop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent i =new Intent(getApplicationContext(),BroadcastService.class);
            stopService(i);
        }
    });

}

private boolean runtime_permissions() {
    if(Build.VERSION.SDK_INT >= 23 && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED){

        requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.SEND_SMS,Manifest.permission.RECEIVE_SMS},100);

        return true;
    }
    return false;
}


@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(requestCode == 100){
        if( grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED){
            enable_buttons();
        }else {
            runtime_permissions();
        }
    }
}

BroadcastService.java

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@SuppressLint("MissingPermission")
@Override
public void onCreate() {
    Toast.makeText(this, "Services has been started", Toast.LENGTH_SHORT).show();
    listener = new LocationListener() {

        @Override
        public void onLocationChanged(Location location) {
            Intent i = new Intent("location_update");
            i.putExtra("coordinates",location.getLongitude()+" "+location.getLatitude());
            sendBroadcast(i);
        }

        @Override
        public void onStatusChanged(String s, int i, Bundle bundle) {

        }

        @Override
        public void onProviderEnabled(String s) {

        }

        @Override
        public void onProviderDisabled(String s) {
            Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(i);
        }
    };

    locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);

    //noinspection MissingPermission
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,3000,0,listener);

}

@Override
public void onDestroy() {
    super.onDestroy();
    if(locationManager != null){
        //noinspection MissingPermission
        locationManager.removeUpdates(listener);
    }
}

应用程序终止。

Answer 1

并非所有制造商都会出现此问题。官方文档没有具体说明是否需要请求此权限。一些制造商在实施 sendTextMessage 时遇到问题，因此需要 READ_PHONE_STATE 许可。

要解决此问题，唯一的解决方法是将此权限添加到您的清单和 requestPermissions。
