Error in AsyncTask with parameters

Question

I'm trying to create an AsyncTask with Context as parameter onClick of a button of a Alert.

But I am getting the error:

No enclosing instance of type is accessible Alerts. Must Qualify the allocation With An enclosing instance of type Alerts (egxnew A () where x is an instance of alerts).

Alertas.java

public static void alertaHorarios(final Context context, final PerfilObj perfil)  {

    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View v = inflater.inflate(R.layout.alerta, null);       
    builder.setView(v);

    sonidos(context);

    cargarAlerta(context,
            v, 
            R.drawable.iconodescargar, 
            "Descargar datos", 
            "¿Desea descargar de internet los datos (horarios y tarifas) de " +
                    "<font color='" + 
                    context.getResources().getColor(Modulo.cargarColorAplicacion(context, perfil.getColor())) + "'><b>" + 
                    context.getResources().getString(R.string.app_name) + "</b></font>?",
            perfil.getColor());

    builder.setPositiveButton("Descargar", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {

            Modulo.reproducirSonidos(context, perfil.getSonidos(), sound, sonidoBoton);

            tareaAsincronaInicio task = new tareaAsincronaInicio(context, perfil);
            task.execute();

        }});
    builder.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {

            Modulo.reproducirSonidos(context, perfil.getSonidos(), sound, sonidoBoton);
        }
    });      

    AlertDialog dialog = builder.create();
    dialog.setCanceledOnTouchOutside(false);
    dialog.show();

    Button b = dialog.getButton(DialogInterface.BUTTON_POSITIVE);

    if(b != null) {
            b.setBackgroundResource(COLOR_FONDO_BOTONES);
            b.setTextSize(TAMANO_FUENTE_BOTONES);
            b.setTypeface(Modulo.fontPrincipal(context));
            b.setTextColor(context.getResources().getColorStateList(COLOR_FUENTE_BOTONES));
    }

    Button b2 = dialog.getButton(DialogInterface.BUTTON_NEGATIVE);
    if(b2 != null) {
        b2.setBackgroundResource(COLOR_FONDO_BOTONES);
        b2.setTextSize(TAMANO_FUENTE_BOTONES);
        b2.setTypeface(Modulo.fontPrincipal(context));
        b2.setTextColor(context.getResources().getColorStateList(COLOR_FUENTE_BOTONES));
    }
}

private class tareaAsincronaInicio extends AsyncTask<Void, Integer, Boolean> {

            private Context mContext;
            private PerfilObj perfilObj;

            public tareaAsincronaInicio (Context context, PerfilObj perfil){
                 mContext = context;
                 perfilObj = perfil;
            }

...
}

I have a class Alerts with many methods with differents alerts. In a alert onClick I call a AsyncTask — user3580822, Apr 29 '14 at 10:26

If the AsyncTask code is written inside the Fragment/Activity as an inner class it is better to use YourActivityName.this instead of the context as Raghunandan commented.

If the code is is written outside the Activity/Fragment you can either use the BaseApplicition context cause if you use the Activity context might leak the activity. This can happen when the activity close's before the task is finished.

I have edited my code. Alertas class not is Activity/Fragment – user3580822 Apr 29 '14 at 10:37

Just use YourActivityName.this instead of passing the context to the AsyncTask.
