Android :: Service Stops When Activity Is Closed
Nov 23, 2010If I understand it correctly, bindService() with BIND_AUTO_CREATE will start a service and will not die until all bindings are all unbinded.
But if I bindService(BIND_AUTO_CREATE) at onCreate() and hit back button to close the activity, the service calls onDestroy() and dies also.
I don't call unbind() at anytime. So is that mean when the Activity got destroyed, the binding got destroyed also and the service gets destroyed also?
What if I want the service to be always running, at the same time when the activity starts I want to bind it so that I can access the service?
If I call StartService() and then bindService() at onCreate(), it will restart the service at every launch of Activity. (Which I don't want).
So I could I start service once and then bind next time I launch the activity?
Android : How To Listen A Closed Activity From A Widget
Oct 8, 2010I have a widget that launches an activity, but when the activity finishes using the finish() I don't know how my widget can know about it since I can't override onActivityResult() which seems like the only way to listen when an activity closes...?

View 2 Replies View RelatedAndroid :: Remote Service Destroyed When Main Activity Closed / How To Fix?
Nov 19, 2010I wrote an android program that: has a main activity for UI, and it starts a service. The service timely callbacks the UI activity to update views. It works fine except: if the activity is closed (with BACK) and start again, the service will also be started again (The service plays audio file, so there are two overlapped sounds). I use bindService with BIND_AUTO_CREATE flag to start and connect to service. According to the document, it should create service only if it doesn't exist, but obviously it starts another instance when opened second time. All I want is when the activity is closed, the service goes on running, and when the activity opens again, it can reconnect to the service. Is that possible? Or I just misunderstand the usage of service?
View 1 Replies View RelatedAndroid :: Static Fields In Activity Classes Guaranteed To Outlive Create / Destroy Cycle?
Oct 28, 2009I frequently run into the problem that I have to preserve state between several invocations of an activity (i.e. going through several onCreate()/onDelete() cycles). Unfortunately, Android's support for doing that is really poor. As an easy way to preserve state, I thought that since the class is only loaded once by the class loader, that it would be safe to store temporary data that's shared between several instances of an activity in a static Bundle field. However, occasionally, when instance A creates the static bundle and stores data in it, then gets destroyed, and instance B tries to read from it, the static field is suddenly NULL. Doesn't that mean that the class had been removed and reloaded by the classloader while the activity was going through a create/destroy cycle? How else could a static field suddenly become NULL when it was referencing an object before?

View 2 Replies View RelatedAndroid :: Contact Custom Fields
Jun 9, 2010Alright, I'm a little new to the Android SDK, so forgive me if my question doesn't make sense or is very trivial. I'd like to add a custom field for contacts, that contains the contacts username on a website I'm doing this app for. And, with this custom field, I'd like to have the ability to click it (like "Send message" or "Call mobile") so that I can go to a specif Activity in my application, with a TextView set with the username that I just clicked on.Sorry if that is a bit confusing, if you need anything else let me know!

Feb 3, 2010I would like to use EditTextPreference to show 2 input fields instead of 1. For instance, a username and password field should be shown. I don't want to use a dialog for each one.

View 1 Replies View RelatedAndroid :: Combining Subclasses Which Have Different Fields For Efficiency?
Feb 7, 2010I'm working on a Java Android game. Games here generally need to use memory pools to avoid garbage collection.Making use of subclasses is a pain when using memory pools as you need to e.g. say how many Roamer and Chaser objects you want upfront and not just how many Enemy objects you might need.I would then have an update function that checked the "type" variable and updated accordingly. This is obviously a more C-like approach. It feels hacky though because e.g. a roamer enemy will have a "target" variable it never uses. I'm unlikely to have more than a 100 enemies in memory at a time though so it really isn't a big deal memory wise. I just want some compromise between nice code and speed.Does anyone have any comments on how best to structure this? Is merging classes like this going too far? Is this ever a good idea? Should I just use a regular class tree?

View 5 Replies View RelatedAndroid :: Private Fields Naming Guidelines
Jan 25, 2010Here http://source.android.com/submit-patches/code-style-guide#shortmethods it is stated that :
"Field Names
* Non-public, non-static field names start with m.
* Static field names start with s.
* Other fields start with a lower case letter.
* Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.
also states that : "The rules below are not guidelines or recommendations, but strict rules. You may not disregard the rules we list below except as approved on a need-to-use basis." I don't like the "m" convention before private or package fields in a class... I really find this uninspired. I mean, if we try to apply good designs, the low coupling of the classes implies having few public fields. actually, in my programs I usually have no public fields, even when I need some I use getters and seters. so, why should I be forced to have almost all my fields in the program with an "m" in front of them? wouldn't be easier to have the few public fields, if there are any, with some "g" in front or something? or just use setters and geters as beans suggest? this really makes my code harder to read. also, following these guidelines, local temp variables used in the methods have no restriction so they could easily be mistaken for public global fields (also without restriction). this also I find to be wrong, as it is a probable source of mistakes. I understand to have a way of differentiating from fields, but private/protected member fields are the most used in an application, they shouldn't be less "readable". what do you think? should I follow the guidelines?

View 4 Replies View RelatedAndroid :: How To Implement Custom View With Variable Fields?
Jul 7, 2010I have a ListView that displays a set of notes, each with varying ammounts of data (i.e. some have a due date, others don't).Currently, each view in the list is a RelativeLayout containing a TextView for each field, plus two Button and a CheckBox. I then simply hide the unused fields by setting visible false on each one.This has worked well, but I'm about to add a lot more data fields to the notes and inflating that many unneeded views for each row will surely kill my app. I need a more dynamic solution.I've decided the best way to go is to create a custom view. How can I implement/design my view so that it can display a variable number of text fields without creating/ destroying textviews each time (which would be quite expensive and worse than my current situation), or maintaining a large pool of hidden textviews?

It does not compile on 2.1. The static fields DIRECTORY_PICTURES, DIRECTORY_MUSIC etc. Don't seem to be found. Using the filter api checkbox, I see that it was removed in Android 2.2 (or api version 8). So the manifest file needs to contain minSdk defined as 7.
