GPS位置更改时如何将Android应用程序带回前台

Question

I am building a Android application which gives Travel Maps.User can navigate away from my application. Ex - Pressing Home button. I want do is, bring back the application on location change.I want to show some notifications on special GPS coordinates. I am using onLocationChanged() method to do my tasks. But I cant find out a way to bring the app to foreground. Can you please help me?

Answer 1

I don't think you can have your application come to the foreground like that but you can probably show a notification in the notification bar instead. When the user selects that notification you can show your application again.

Answer 2

First I have not done this. But at least you can try. Inside onLocationChanged() callback put

Intent startActivity = new Intent(this,your_class.class ); 
startActivity.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); 
PendingIntent i = PendingIntent.getActivity(this, 0, startActivity, 0);

Then start that Intent.
