View 2 Replies View RelatedAndroid :: Application Object Life Cycle
Sep 30, 2009When I start my application I prompt the user for the password and use it to instantiate my data adapter object that I will need throughout the application. So I store it in Application object. My activity A prompts user for pwd, instantiates data adapter, sticks it to Application object and later starts activity B which in turn starts the built int gallery activity. When fooling around with gallery and capturing pictures for some time coming back to activity B I discover that Application.myDataAdapter is null. I found out that during me playing with camera the Application.onTerminate() method was called. So it seems like Android killed my process and when B was supposed to become visible it started a process again jumping directly to activity B bypassing A? Is that how it works? Should I then never assume that Application.myField will survive? and init it not only when A is started but whenever I discover it is null?

Android :: Does An App Only Have One Context Object
Jul 19, 2010I'm confused about the concept of the Context class. I see that it's a base class of Activity, but the Android docs also mentions the Context storing global information about the app environment. So in my app which has 3 activities, does that mean I have 3 distinct Context objects, or do they actually refer to 1 entity? Also, what is the lifetime of a Context object- does it live until the last component of this activity's process is garbage collected?

View 3 Replies View RelatedAndroid :: Saving An Object For Use Later
Jun 12, 2010As part of my widget, I use an instance of the Camera object.
This is what I want to do. The user will click on my widget, I get an instance of the Camera(if it's not already stored), use it, then store it. If they click the widget again, I want to use that same instance that I used previously.
I can't release the Camera(android.hardware.Camera) until the user clicks on the widget the second time. So the user clicks on the widget the first time, I get the camera and hold on to it until they click the widget again.
The problem I am running into is on the second click, I am trying to get the Camera again, which I can't because I currently have it in use.
Android : Getting Object From ContentProvider
Aug 12, 2010I have a custom class, which represents my data-structure. This custom class is in a normal Java-library, which is included in both projects. I have one Project with a ContentProvider which provides this data to Activities of other Projects. And an other Project with an Activity, where I want to handle this data in objects of this custom class.
How can I get this data to the Activity? The Cursor [1] only supports primitive Types.

Android :: Sharing An Object Between Activities
Nov 24, 2010I have a Weather app with four Activities. The main/launcher activity is 'invisible' using...
android:theme="@android:style/Theme.Translucent.NoTitleBar"`
Aand is simply used to do a few checks (whether this is a new install, whether a network connection is available etc) before firing off one of the other Activities. The other Activities are UI-oriented - two simply display weather data pulled from a website and the third to provide a location 'picker' so the user can choose which area to show the weather for.
However, all four activities make use of a WeatherHelper object which basically does everything from checking for available SD card storage to maintaining preferences and pulling/formatting website pages.
So, my question(s)...what is the best way to have one instance of WeatherHelper which can be used by multiple activities and where/how are best to create it in my case?
I've been an OO programmer for a lot of years but I'm very new to Android and the design concepts - I've read a lot on the Android Developers site over the past weeks but I've stalled trying to decide on this.
Android :: Singleton Object With Context?
Oct 10, 2010I often run into the following dilemma: I need some singleton-like object in my app (typically some central manager-like thing) and this object needs a context for various things. This means that I either have to pass a context to all methods needing one or have some sort of init-pattern to the object. Neither is pretty I think. What is the correct way of doing this? Or is this simply (even the definition of) a Service?

View 2 Replies View RelatedAndroid :: Spinner With A Complex Object
Aug 3, 2010All the examples I have found assume that Spinner is given an array of String. I have a Spinner whose Adapter contains an Object more complex than a String. I want the capacity to display some parts of this object. a) during drop down b) when the item is selected. Nothing fancy, just some straight text, but I need ot whole object. If I override Adapter#getView, the View that super#getView returns is a TextView, so I could set that to be some relevant text value, but it feels kind of undocumented. I did try inflating a layout containing 2 TextViews and populating them, but UI became a bit screwed up. I'm not really sure what's ok to change here and what's not. Likewise, the above presumably applies to the drop down view, but I am also not sure how to render the selected item.

Android :: Can't Load Drawable Object / Want To Know Cause Of It
