Send flag to finish an activity from any other class

Question

I have a class (Not an Activity) that has a stack of activities in background. Some times, I want to close an old activity from that stack, but most of the times the activities are so in background that if I use finish(), it doesn't work.

So, I was thinking on using putExtra to send the message to that activity so it can close on the onResume().

I'm trying to do it this way without success:

On my NoActivity.class:

public void removeActivityFromStack(Activity activity){
    for(int i = mActivityStack.size(); i>0; i--){
        if(mActivityStack.get(i - 1).equals(activity)){
            mActivityStack.remove(i-1);
            activity.getIntent().putExtra(CLOSE_ACTIVITY, true);
        }
    }
}

And on the MyActivity.class:

@Override
protected void onResume() {
    super.onResume();
    Bundle bundle = getIntent().getExtras();
    if(bundle != null && bundle.getBoolean(getString(R.string.bundle_cerrar_activity), false)){
        this.finish();
    }
}

Any help will be appreciated.

I also tried using BroadcastReceiver to close those activities, but it still doesn't work. I tried the next way:

On my NoActivity.class

    public void removeActivityFromStack(Activity activity){
        for(int i = mActivityStack.size(); i>0; i--){
            if(mActivityStack.get(i - 1).equals(activity)){
                IntentFilter filter = new IntentFilter();
                CloseActivitiesBroadcastReceiver baseActivityReceiver = new CloseActivitiesBroadcastReceiver();
                filter.addAction(CLOSE_ACTIVITY);
                current.registerReceiver(baseActivityReceiver, filter);
                current.sendBroadcast(new Intent(CLOSE_ACTIVITY));
                mActivityStack.remove(i-1);
            }
        }
    }

And on CloseActivitiesBroadcastReceiver.java:

public class CloseActivitiesBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(context.getString(R.string.bundle_cerrar_activity))) {
            ((Activity)context).finish();
        }
    }
}

Okay, this is a Little dirty answer, but is the only one that I could make work. If somebody gets a better answer, post it.

On my NoActivity.class:

public void removeActivityFromStack(Activity activity){
    for(int i = 0; i<mActivityStack.size(); i++){
        if(mActivityStack.get(i).equals(activity)){
            activity.finish()
            mActivityStack.remove(i);
        }
    }
}

This way, if the activity is in foreground, will close on finish(). Else, it won't close at all. But for this case:

On the MyActivity.class:

    @Override
    protected void onResume() {
        super.onResume();
        if(!mNoActivityInstance.getActivityStack().contains(this)){
            finish();
        }
    }

In my case, NoActivity.class works as a Singleton
