Now I need to be able to pass this same object to other functions in the code, such as the onOptionsItemSelected function. I currently have it where I just create a new WebView object in each function where I need it, but this slows down the code since it has to recreate it and such.

Every Surface source in the API that I can see, though, requires a View that's laid out before the Surface becomes available. Are there other ways to create a Surface that I am missing, and can you point me to them?

This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

I have a Cursor points to a Contact. How can I get an url built from that Cursor?
I need to know that because from here: http://developer.android.com/guide/topics/providers/content-providers.html
I need to have an url so that I can build a phone uri, like this: phoneUri = Uri.withAppendedPath(uri, People.Phones.CONTENT_DIRECTORY);
and I can query all the phone numbers for that contact.
I'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?

This is not related to dragging objects.I could see this drag feature working on home screen of the phone to move the home screen left and right. But couldn't figure out how it works. Please provide information on which class and methods to be referred for this.

View 3 Replies View RelatedAs 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.
I 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.

I 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.
I 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 RelatedAll 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.
