Android :: Activity Finish Method Waits To Finish?
Aug 14, 2010With this sample code, the activity is told to finish, but continues execution afterwards and displays the message. I'm trying to understand why this happens. The only fix I can think of is to place 'return' after finish.
public void someMethod() {
if( valueIsTrue) {
startActivity(new Intent(this, NewActivity.class));
CurrentActitivy.this.finish();
// return; // if uncommented, Toast doesn't show
}
Toast.maketext(this, "Some message", Toast.LENGTH_SHORT).show();}
Android :: Shouldn't Calling FinishActivity Cause Finish To Be Called?
Nov 11, 2010I have overridden the finish call in a sub-activity like so

I am calling finishActivity on this sub-Activity from the Activity that started it for result. But I am not seeing the finish being hit. Instead it goes directly to onPause.
Android :: TextView With URL Throwing Exception When Finish() Called In OnResume()
Apr 6, 2010I created a TextView and put an url to it, using setText(Html.fromHtml("");. Its opening the web page in the built-in browser and when I press back, its coming back to the application.
I don't want to come back to the application, so in activity's onResume(), I call finish(). Its exiting at the first time. But when I open the application again, its throwing some exception.
Any other way to close the application, other than this way.
Android :: SingleTask Really Always At Root Of Activity Stack?
Sep 16, 2009In the documentation it is stated that an activity with launchMode="singleTask" is always at the root of the sctivity stack. However, when I run my "singleTask" activity for a few scenarios and monitors behaviour with "adb shell dumpsys activity" I can see it placed both at the top of the stack (with numActivities=2) and in the middle of the stack (with numActivities=3). The activity at the root (frontOfTask=True) has a "normal" launchMode.Is the documentation incorrect or am I missing something?

Feb 18, 2010I have an activity, ActivityA, and its launchMode is set to "singleTask".I start the application from the app tray. ActivityA launches ActivityB from a button click. ActivityB is a normal activity with no launchMode set ("standard").With ActivityB on top of the activity stack, I hit the home button, then resume the app, I see ActivityA instead of ActivityB when resumed.Shouldn't the history stack be preserved in this case, and B be showing? When I resume, I see A get onNewIntent() called, and I'm not sure why this is happening. I thought the stack would be preserved.
View 1 Replies View RelatedAndroid :: Way To Pass Bundle To Activity Set As Singletask?
Apr 22, 2010So I have a MapActivity that runs an asynchtask that occasionally updates what exactly it's displaying on the map (via a string). I originally pass this string in from the intent when the activity is first created. And then if you click on one of the drawables on the map, it opens a new activity, which can then create a new mapview (same class) with a different string setting. The problem I have is that I only want one instance of the mapview to be running at once. Thus I set android:launchmode="singletask" in the manifest. This works in that it brings the mapactivity to the front, but is there any way to send it a new intent bundle to get a new setting for the string it needs? I tried regetting the extras from the bundle, but it seems to retain the old bundle, not the new intent that was passed to it. I'm not sure I want to do startActivityForResult because the 2nd activity may or may not want to update the original activity. I hope that made sense. I can post code if necessary, but I think that should explain my situation.
View 2 Replies View RelatedAndroid :: Effect Of PostDelayed() In Activity After OnPause()?
Nov 22, 2009I tried the following from an activity:
@Override public void onPause() { super.onPause();
postDelayed(new Runnable() { public void run() { mTextView.setText("I am paused!"); }, 10000); }
The activity, while in the background, still executes the runnable. Is this incorrect? Should we absolutely call removeCallback() from our onPause() handler to ensure that no postDelayed() runnables execute if we get paused? Or is it necessary to do this only in onDestroy()?

View 1 Replies View RelatedAndroid :: OnPause / OnResume Activity Trouble
Mar 14, 2010I have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app.
From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity.
Android :: OnPause() - Resume To An Activity Which Has A Bundle Passed To It When Created
Mar 11, 2010I have an application where I navigate from Activity A to Activity B and back to A and then B. I want to resume the activity B (which has a Bundle passed to it ) from Activity A. The documentation says that OnSaveInstance() is called only when the activity is killed, so how do i use OnPause which does not have the Bundle to resume the activity B.

View 1 Replies View RelatedAndroid :: Finish Activity Not Started From Current Activity
May 1, 2010I have following problem with my application: From my main activity ("activity 1"), there is a menu from which user can launch an action. This action will result in an Intent being received by a BroadcastReceiver, defined in my application. Finally, this BroadcastReceiver will start an activity ("activity 2") to deal with this intent.
The problem is that I have a "quit application" entry in my menu, and I can only finish() currently active activity. ie I am not able to finish "activity 1" from the menu of "activity 2". And I can't use startActivityForResult() as "activity 2" can't be started from "activity 1". Any suggestion would be much appreciated Thank you very much guys, regards.

So i am wondering is there any way by which i can finish another activity from my current activity. Or should i override the OnKeyDown Method..

View 1 Replies View RelatedAndroid :: How Finish An Activity In This Instance
Aug 16, 2010We all know that hitting the back button on the device doesn't kill the application, it merely finishes (destroys) the activity running on the foreground.
Well I have come across some code which helps me capture the back button signal so that I cannot exit the application. The only way to exit it in such cases is to press the home key.
Now this situation presents me with a unique disadvantage! The inability to kill finish the application on a time of my own choosing allows the application to keep running in the background like nothing has changed.
So in such cases is the task manager my only friend or is there a way for me to otherwise kill this application?
Android :: Activity Pause Rather Than Finish?
Nov 30, 2009I see no means by which my activity can pop itself off the activity stack to return the user to the one he was using before it was invoked. Is there one? My purpose is that my app has some data structures built from data provider queries that take 5-15 seconds to assemble and I don't want a lot of latency if it is used in a few one-shot purposes in rapid succession. I'm more than willing to let the system ask my app to die, but I'd like to keep warmed and ready otherwise.

Sep 7, 2010I have one activity call a camera view activity, and in the onActivityResult, I have it start that activity again with different parameters. Android doesn't seem to like that, and gives me an error that the camera is not available if I start it right after it returns. I tried just waiting a few seconds, but this doesn't seem to work on all phones, and it sometimes crashes. Is there some way to wait until that activity finishes properly, and gives up all resources?
View 6 Replies View RelatedAndroid :: Finish Not Killing Activity
Apr 12, 2009I've got an application that has (among other things) three Activities, let's call them A, B, and C. A is the main navigation point for the entire application, and launches B and C directly using startActivity(). They work fine that way. However, when I call C from inside B, I get a strange problem. The code for launching Activity C is exactly the same in both places. The problem is the hardware back button. In the emulator, it takes two presses of the back button in order to close Activity C and come back to B. On a G1, it takes 3 or 4 presses. Upon seeing this, I implemented the usual suspects in C - onPause(), onStop(), and onDestroy(), and onResume() in B. When I press the back button from C and it doesn't work, I get onPause(), onStop(), onDestroy () - in that order, but nothing happens. When it works (on press 3 or 4 on the G1), I get onPause(), then onResume() in B, then onStop() and onDestroy().
I've tried catching the key press of the back button and calling finish (), but that doesn't make a difference. Has anyone seen this? To pre-empt some questions: All C does is display some data. There are no threads or any other special resources that C might have an active handle to that's preventing it from closing. But out of curiosity, if it did, how would I detect that? Any ideas for further diagnostics here?
Android :: Finish() Won't Close Activity
Jul 23, 2009I have an EditText field and I want to pop up a new window/activity whenever a user touches/clicks the field. The new window has some widgets and of course Apply and Cancel buttons. Here is the code how I intercept the onTouch event.
EditText ctlMaskEt = (EditText)findViewById(R.id.mask_field); ctlMaskEt.setOnTouchListener(new OnTouchListener() { public boolean onTouch (View v, MotionEvent event) { popMaskEditor(); return true; } });
Everythings work fine until I click the Apply and Cancel buttons. The API finish() won't close the new window unless I click the same button one more time. Calling popMaskEditor() from a button's OnClick event handler doesn't have this problem.

Android :: Does Pressing Back Always Cause Activity To Finish()?
May 10, 2010I've heard that pressing the back button will essentially cause the current Activity to finish(). Is this always the case? Seems like it would be with the way it pops the Activity off the stack.
The one situation I'm not so sure about is when the root Activity in a Task has back pressed. I'm currently experiencing a very weird effect, described as follows:
On loading my application, the first Activity is for initialization, and once it finishes, it calls my main Activity (a TabActivity). This first init activity has android:noHistory="true" set in the Manifest so pressing Back from my main Activity won't go back to that. It goes to the Launcher. When I click on my App in the Launcher a second time, the initialization activity loads again, and loads the main Activity when done. Almost immediately after, it loads a second instance of my main Activity. But ONLY after the Application has already been run once, and was exited by pressing BACK from the main Activity. It does it every subsequent time until I force quit the app or load a new version from the IDE.
Based on this, I am suspecting some kind of Activity instance is lying around and being reused, since it only happens on the second+ time I run the application (and exit with BACK -- using HOME just returns to the last state of the app, no big deal).
Android :: Finish Activity From Custom BaseAdapter

Android :: Finish Parent Activity From Child?
Mar 30, 2010My child activity X is called from Parent activity P through startActivity(intent). I want to close P when X called its finish() method. I override a method finishFromChild(Activity child) in P and called finish() in it. But this functions (finishFromChild(Activity child)) is not being called after X finish() Is it a known bug or I am missing some thing? I googled and also searched the groups but no help.
An alternative could be... using StartActivityForResult() and a "fake" onActivityResult, where I can finish the parent activity, but this way is quite bad, i think...
I prefer the first one, if it would work....
Android :: Calling Finish() After Starting A New Activity
Apr 26, 2010The first Activity that loads in my application is an initialization activity, and once complete it loads a new Activity. I want to ensure if the user presses 'Back' they go straight to the Launcher, and not the initialization screen. Side note, is this even the best approach, or would this be better done with some kind of Intent Flag?
Is it correct to call finish() after calling startActivity() on the new activity?
CODE:...................
I'm still taking in the whole 'Message Queue' method of doing things in Android, and my assumption is that calling startActivity() and then finish() from my first Activity's onCreate() will log each respective message in the message queue, but finish execution of onCreate() before moving on to starting the next Activity and finishing my first one. Is this a correct understanding?
