how to maximize the application on an event?

Question

I have minimized my app using this..

                Intent startMain = new Intent(Intent.ACTION_MAIN);
                startMain.addCategory(Intent.CATEGORY_HOME);
                startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(startMain);

The app is waiting for some event while it is in minimized state.How can i return to the app activity when some broadcast event occurs?

i can access the minimized activity from the the broadcast receiver class(using an object passed to it earlier) but it is running in the background of home screen.

and does android kill minimized apps eventually?

look into this code http://stackoverflow.com/questions/3849868/startactivity-from-broadcastreceiver — Vishal Pawar, Aug 30 '12 at 11:46
i dont want to start a new activity...reopen the minimized one.. — Amel, Aug 30 '12 at 11:52
No, you did not `minimized` your application. There's not such thing in android. — Marcin Orlowski, Aug 30 '12 at 11:54
add this android:launchMode="singleInstance" in your activity tag in manifest — Vishal Pawar, Aug 30 '12 at 11:56
@Webnet,well Eldhose's code worked for me..Thanks Sathya,Eldhose — Amel, Aug 30 '12 at 12:05
I said there's not such thing like minimizing application on Android. All you did you launched something else, therefore your app's Activity was paused and went to background — Marcin Orlowski, Aug 30 '12 at 12:10
sorry its my mistake..i should have used the term "gone to background" insted of "minimized"..i wanted to know if there was any way to bring it back to front.thanks man.. — Amel, Aug 30 '12 at 12:15

Intent homeIntent = new Intent(this, HomeActivity.class);
homeIntent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(homeIntent);

this will start the HomeActivity, if the activity still in memory, it will just bring it to front.

doesn't it have the same effect without mentioned flag? – Malachiasz Feb 10 '14 at 11:03

if there is instance of the activity in the history, it will not start a new instance of the activity – Mohammad Ersan Feb 10 '14 at 14:38
I see, I defined my activity as singleInstance, that's why I haven't seen any difference. – Malachiasz Feb 10 '14 at 14:46
This is a perfect answer – dd619 Jan 23 '15 at 09:08

You can start the activity again using the Intent.

Example :

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity"));
startActivity(intent);
