How to bring an activity to front in android?

Question

I am using moveTasktoBack() function to send my activity to background. I want to bring my activity to front when a timer in my activity finishes. I am using the phone back key to send the activity to back. How do I do that? Help please.

@EricSchlenz actually that link discusses how to rearrange activities within a task. This doesn't solve OP's problem. He wants to know how to bring a task from the background to the foreground. — David Wasser, Apr 22 '15 at 16:12
To bring a task to the front, see http://stackoverflow.com/a/29769255/769265 — David Wasser, Apr 22 '15 at 16:13
why so many answer to confuse! when each intent flag has different meaning and purpose. — Shubham Agarwal, Oct 08 '15 at 11:51

Exact Same issue that is mentioned on this Question.

Sloved it with following code snippet. i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); actauul which brings back the activity to front.

Intent i=new Intent(ApplicationStatus.this,NotifyActivity.class);
                    //i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
                    i.putExtra("ID_TimeLeft",String.valueOf(TimeLeft));
                    startActivity(i);

I think it should be FLAG_ACTIVITY_SINGLE_TOP.

You can use intent with the appropriate flags. FLAG_ACTIVITY_NEW_TASK to create a new task to contain your activity if one doesn't already exist. FLAG_ACTIVITY_REORDER_TO_FRONT to bring your activity to the front of the task if it's not already there.

Intent intent = new Intent(context, YourActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(intent);
