Newbie Question from an iPhone developer.
I have called the startActivity(intent) and the new activity loads. How do I go 'back' to the calling activity once a button is pushed. 'Popping' the activity off the stack basically.

I currently have an application that naturally gets pushed to the background when the home key is pressed.
The activity losses focus but continues running in the background.
So I want to know is it possible to bring the application back to the foreground when the user presses the green key (call button) on the device?
I have various activitys on my app. I have a configuration Activity, and i want to put a cancel button, that, when user press this button, the configuration window get's closed and turn back into the previous activity.i search in google and i find something about calling cancel or dismiss functions, but i can't call them cause this is not a dialog, it's an activity
View 1 Replies View RelatedI have an application with contains multiple activities. The main activity will start the others ( use startActivity() ) depends on user event, when an activity close, it calls finish() and return back to main activity. It appears to behavior like that.
However, the "problem" I see is main activity's onCreate function is called every time. I think the the main activity should be placed in the activity stack and simply push to front when others exit, therefore only onResume, onStart are called. Is there some flag I need to set or I misunderstand the activity behaviro?
In child activity, besides calling finish() or startActivity for main activity, what is other way to move main activity to front?
so i have factory reseted my phone twice and used wakelock and i cant find a solution. looked through forums and found possible answers but all failed. i press the lock button on the right side then after about two seconds it turns right back on. when it sleeps again it turns right back on .. i have not found a solution to it. i have the 4.3 jellybean on it. the only solution that sometimes works is a lock screen app that i downloaded from the play store. but it really sucks when i get a message the screen turns on right then after it goes off then turns right back on .. so if i miss any notification it drains my battery because my phone wont stay off.

View 2 Replies View RelatedI have a app with 2 activities, A B A has a button that launches a new intent for B. When at B I press home, then launch app again, B is resumed with onResume(). But if after I press home, I use something like taskiller to clear tasks, then I launch app again, it still shows B, but onCreate() is called. What I want for the second situation is for the app to start A instead of B. How can that be done?

Here is a flow graph showing how activities are invoked currently. Main is short for MainActivity and Twit for Twitter Activity. startActivity() OAuth intent OAuth callback finish()Main ---------------> Twit ------------> Browser --------------> Twit --------> Browser As you may notice, after the TwitterActivity calls finish() to stop, it will now return back to MainActivity, but Browser instead. How can I make it return back to MainActivity?

View 2 Replies View RelatedI have 3 classes in my example:
Class A, the main activity. Class A calls a startActivityForResult:
Intent intent = new Intent(this, ClassB.class);
startActivityForResult(intent, "STRING");
Class B, this class is a TabActivity:
Intent intent = new Intent(this, ClassC.class);
tabHost.addTab...
Class C, this class is a regular Activity:
Intent intent = this.getIntent();
intent.putExtra("SOMETHING", "EXTRAS");
this.setResult(RESULT_OK, intent);
finish();
onActivityResult is called in Class A, but the resultCode is RESULT_CANCELED instead of RESULT_OK and the returned intent is null. How do I return something from the Activity inside a TabHost?
I realize that the problem is that my Class C is actually running inside of Class B, and Class B is what is returning the RESULT_CANCELED back to Class A. I just don't know a work around yet.
I'm really new in Android programming, so I have a simple question getting a phone number from contacts in my application. The method I want to implement is that the user clicks a button in my app and will be forwarded to the contacts. In contacts user has to click on a phone number and this number should be returned to a textfield. Is there a simple way to do this instead to implement it by ContentResolver?
View 1 Replies View RelatedMy MAIN activity is spawning a child activity that contains a ListView. While this ListView is being populated (through an AsyncTask), an indeterminate progress bar is shown.However, assuming that I am an impatient user and I press the BACK button, the progress bar is cancelled but I am left with a blank screen. I have to press BACK one more time to go back to the MAIN activity.I would like the app to go back directly to the MAIN activity by pressing BACK only once. Can somebody point me in the right direction? I am thinking I should call finish() somewhere but I don't know where to put it.
View 3 Replies View RelatedI have a widget that when clicked opens an activity from same app as the widget. When the activity is closed/dismissed via a button, the user will see the full app window IF the app was previously open/in memory. Is there a way for the activity to finish and return to the home screen and not to an existing instance of the app?
Intent i = new Intent(this,RateIt.class);
i.putExtra("com.sporadicsoftware.NetQ.movie_id",aMovie.title_id);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET|Intent.FLAG_ACTIVITY_NO_HISTORY|Intent.FLAG_ACTIVITY_CLEAR_TOP);

I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.
I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".
How would I force the current thread to wait until another has finished before continuing. In my program the user selects a MODE from an AlertDialog, I want to halt executing of the program before continuing as the mode holds important configuration for the gameplay.
new AlertDialog.Builder(this)
.setItems(R.array.game_modes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case 0:
setMode(TRAINING_MODE);
case 1:
setMode(QUIZ_MODE);
default:
setMode(TRAINING_MODE);
break; ............
//continue loading the rest of onCreate();
contineOnCreate(); } })
.create().show();
If this is impossible can anyone give a possible solution?
I have an android application with a LOT of activities, think of something like a book where every page is a new activity. The user can make changes in each activity, for example highlight certain texts with different colored markers etc. and it's crucial that I'll remember this information as long as the application stays alive (and I don't want/need to remember any of this when it's not). As I understand the best mechanism for storing this kind of information is via onSaveInstanceState(Bundle outState) and onCreate(Bundle)/onRestoreInstanceState(Bundle) rather than lets say, the Preferences mechanism. My only problem is that the user can navigate backwards to previous pages (Activities) and the only way i know of achieving this is by calling finish() which of course kills the current activity without calling onSaveInstanceState(Bundle outState) and even if it did call it, the next time I would launch an activity representing that page it would be an entirely new instance. So my question is: Is there a way to go back to the previous activity without calling finish()? or, is there a better way to save this information? maybe through static variables?
