My App is Launched by "Main.java" (Activity) and opens a Notification and a second Activity called "Sub.java", now I press the Home-Button and the App disappears (everything okay until here). If I'll now click on the Notification the "Main.java"-Activity is launched, the "Sub.java" seems to be lost. Is there any possibility to reorder the Stack of Activities to the front?

I am having trouble popping all activities off the stack using ntent.FLAG_ACTIVITY_CLEAR_TOP and android:launchMode="singleInstance". In my application activity A, launches activity B (via startActivity) which in turn launches activity C (via startActivity). On activity C the user presses a menu item to return to activity A. When they arrive at activity A, I want only A on the stack such that if they click the back button they return to the home screen (desktop). This is the code that I am currently using when the user presses a button to return to A: Intent i = new Intent(this, A.class); i.addFlags(Intent.FLAG_ ACTIVITY_ CLEAR_TOP); startActivity(i); All activities are defined as android:launchMode ="single Instance" in the project manifest. My code doesn't seem to work though. Once I'm back on activity A if I click the back button I return to activity C. Am I misunderstanding how to use Intent.FLAG_ACTIVITY_CLEAR_TOP?
View 2 Replies View RelatedSupport App starts activity A, then A starts activity B and finishes itself. After that activity B starts activity C. Now the stack contains B and C, with C at the top. Then I click a button in activity C, and want it to clear B and C and start activity A, i.e. I want activity A to be the only activity in the stack. How can I make it?Edit: I made a test to use FLAG_ACTIVITY_CLEAR_TOP. But it didn't work in my case, because activity A is not running when button in activity C is clicked.

Can any one help me in that how to do it programmatically?
I have activity A that starts activity B which starts activity C
A -> B -> C
When a user clicks on a button in activity C, i want to bring A to the top of the stack and take B & C completely out of the stack. Is there a way to do this ? ?
I'm currently debugging my app which is quite complex and has up to 5 activity levels. In order to detect memory leaks (i.e. activities that aren't removed from memory even finish() is called, due to some references held somewhere) I want to check which activities are still alive in memory. Currently I create hprof dumps, but it's not very convenient, cause every time I need to mount the sdcard, copy the hprof dump file from the sdcard to my PC, etc. (Side note: I already tried to automate the pulling of my hprof file more easily, but I'm on an unrooted device and adb pull <hprof file> won't let me / no permission.) Therefore I am wondering, if all I want to know is IF and WHICH activities are still currently alive in my memory, is there a way through the Android API or any other way on-the-fly with which I can achieve this (list all alive activities of my app), programatically.
View 2 Replies View RelatedThe official documentation describes tasks as follows: All the activities in a task move together as a unit. The entire task (the entire activity stack) can be brought to the foreground or sent to the background. Suppose, for instance, that the current task has four activities in its stack three under the current activity. The user presses the HOME key, goes to the application launcher, and selects a new application (actually, a new task). The current task goes into the background and the root activity for the new task is displayed. Then, after a short period, the user goes back to the home screen and again selects the previous application (the previous task). That task, with all four activities in the stack, comes forward. Is there a way to programmatically detect when the task of the current Activity moves into and out of the background? I would like to know when the user has switched switched to another application, vs. when the user navigated to another Activity in the current app.
View 2 Replies View RelatedHi I have an application with several Activities in Android and I want the user to be able to log out by pressing a menu button. The problem I have is that A) Android doesn't let you terminate the applications and B) even when I send the user to the Login Activity again they can always press back and get right back to the previous activity they were in.I already tried to launch the Activity with the two following flags:
Intent intent = new Intent(this, LoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
I also tried with each one of them by themselves. I also tried calling finish() after startActivity(intent) as I read in another StackOverflow

View 7 Replies View RelatedIs there a way to clear our Activity stack? For example, a user in my app progresses through these activities, one is launched from the previous activity: ActivityA -> ActivityB -> ActivityC if the user is now looking at ActivityC, and they hit the back button, they will go back to ActivityB. Is it possible to add a menu to ActivityC where the user can clear their activity stack, and then launch a new instance of ActivityA? This would be so the user can jump to a particular activity in my application without getting confused with the back button + history,
View 4 Replies View RelatedIs there a way to tell when my task gets put on the back of the UI stack (user pressed "home" say?) I have some resources I'd like to free when not foregrounded. The lifecycle routines seem dicey to use to try and infer this. The "home" key does not seem to be passed to onKeyDown(), and moveTaskToBack() is never called by the system so I can hook it. I can poll the ActivityManager for running activities with my task id, but hard to find a good time to call this.
View 5 Replies View RelatedMy main activity A has as set android:launchMode="singleTask" in the manifest. Now, whenever I start another activity from there, e.g. B and press the HOME BUTTON on the phone to return to the home screen and then again go back to my app, either via pressing the app's button or pressing the HOME BUTTONlong to show my most recent apps it doesn't preserve my activity stack and returns straight to A instead of the expected activity B.Is there a setting I'm missing or is this a bug? If the latter, is there a workaround for this until the bug is fixed?

View 7 Replies View RelatedActivities: A & B are activities that once you have navigated away from them it's not logical that you can get back to them using the back button. C X are activities that follow the usual "can go back to where you came from" flow.App flow: * Launch app from Home -> starts A * From A start B * Finish A (removes it from stack) * From B start C * Finish B (removes it from stack) * From C start D * From D start E.Once the user has reached E, the activity stack looks like this: C -> D -> E. Can I somehow reset the whole stack so it starts again at A so it's as the user just launched it from Home (so that C... E are removed from the history stack)?

View 2 Replies View RelatedI'm having trouble with my activities when they go in the background. I have two activities, A and B. Only A can launch B (manifest copied below).This is very confusing. It's like Android knows my app is running, and puts a new instance of A on top of the old B instance running. I'd just expect that the application gets paused in-place, and whenever the user hits the app icon again, it just picks up where it left off (in this case, just show B again!) Below is the manifest, and the activity classes for this test are completely empty (except A which has a button to launch B).
View 4 Replies View RelatedMy app has a single entry activity called "Main". In "Main" I call one of three other activities A, B, or C (based on a preference) and then immediately exit/finish"Main" so that only A, B, or C are active.I also have a permanent notification in the notification bar that users can pull down (at any time) to conveniently restart my App (calls intent with "Main" component).The problem is that if my app is already running and users pull down the notification and restart, I get A or B or C running on top of the previous activity (also A, or B, or C). How can I avoid this (i.e. reuse the activity on top of the stack)?I've tried Intent.FLAG_ACTIVITY_* and nothing seems to work. I've tried launchModel in the Manifest and it also didn't seem to work.
