Android :: Wait For Activity To Finish?

Sep 7, 2010

I 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?

Android :: Wait For All Tasks In An ThreadPoolExecutor To Finish Without Shutting Down The Executor?

Oct 14, 2010

I can't use shutdown() and awaitTermination() because it is possible new tasks will be added to the ThreadPoolExecutor while it is waiting.

So I'm looking for a way to wait until the ThreadPoolExecutor has emptied it's queue and finished all of it's tasks without stopping new tasks from being added before that point.

If it makes any difference, this is for Android.

Android :: Make SAX Parser Wait For File To Finish Downloading Before Parsing?

Sep 20, 2010

I am having a problem where my XML files are slow to load and don't finish downloading before they start to be parsed which throws an xml not well formatted exception from my parser showing that the file downloaded incompletely. The complete error from logcat is "ERROR/Error(323): errororg.apache.harmony.xml.ExpatParser$ParseException: At line 10, column 46: not well-formed (invalid token)" I know the xml file is correct because sometimes it will work and I can also pull it up in my browser and look at it.

What would be the best way to make the parser wait for the InputSource before continuing on and parsing the xml data? The code below is the code I use to get the file and parse it.

SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
GradeHandler gradeHandler = new GradeHandler();
xr.setContentHandler(gradeHandler);
URL url = new URL("https://url/to/xml/file");
HttpsURLConnection ucon = (HttpsURLConnection)url.openConnection();
ucon.setHostnameVerifier(new AllowAllHostnameVerifier());
xr.parse(new InputSource(new BufferedInputStream(ucon.getInputStream())));

Android :: Activity Finish Method Waits To Finish?

Aug 14, 2010

With 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 :: Finish Activity Not Started From Current Activity

May 1, 2010

I 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.

Android :: How To Wait For Service On Activity Start

Nov 2, 2010

I am making an application that has Activity which communicates with a single service, and is used to start, stop or change settings of that service. I used a singleton approach from this tip.

My problem is that busy-waiting is not working for me and I can't attach a listener to the service because activity gets blocked. I want the service to start or get it's current instance at application start so I put the busy-waiting in onCreate. I'm guessing I'm doing this very wrong, so how do I do this appropriately?

Android :: Finish Activity From Other Activity

Oct 8, 2010

I am having application in which i am using menu , on tap on menu item i am redirecting to specified activity. I want to make sure that when i am redirected to another menu item my current all activity should be finished to reduce the stackflow of the activity and better performance. So when i tap on back from my tapped activity from the selected menu activity i should be redirected to another activity and finish current activity. 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..

Android :: How Finish An Activity In This Instance

Aug 16, 2010

We 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, 2009

I 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.

Android :: Finish Not Killing Activity

Apr 12, 2009

I'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, 2009

I 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 :: Finish Activity Doesn't Work

Nov 5, 2009

In main Activity, I called start Activity For Result(intentB, 100) to start a new activity B, then in B, I called startActivity(intentC) to start another activity C. Lastly I wanted to call finish Activity(100) in C to close activity B, but seemed it was not successfully destroyed(I can use BACK key to see it's still there.)

Android :: Finish Activity When Home Pressed?

Mar 25, 2010

I saw another thread related to this question, but did not find the answer that was useful to me. Is it possible when the user presses the Home button to be able to finish() my activity somewhere? I saw that people were having problems with using onStop(). Has anyone found a resolution to see if this is always called on Home being pressed?

Android :: Does Pressing Back Always Cause Activity To Finish()?

May 10, 2010

I'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 Parent Activity From Child?

Mar 30, 2010

My 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, 2010

The 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?

Android : How Activity.finish() / StartActivityForResult() Collaborate With Each Other

Nov 12, 2010

I got a question about Activity.finish(). In my Android code, there are 4 activities(A,B,C,D). The starting activity A calls startActivityForResult(intent, reqCode) to start activity B. B starts C, and then finish(), not waiting for result. C does exactly the same as B, starts D and then finish(). D will return some result, by setResult(resultCode).

When my code runs and activity D returns some result, A will catch a RESULT_CANCELED on onActivityResult(), even if RESULT_OK is returned in D. I guess the RESULT_CANCELED is from activity B, which has been terminated before D returns a result, rather than from D.

But, my question is, why activity A catch RESULT_CANCELED after D returns some result, rather than immediately after B is terminated? And, what should I do to make A catch results from D? Do I have to keep B and C alive, to pass results from D to A?
