I have an activity that loads and displays images from the SDCard. I create a new AVD, specify the desired image of the sd card (which has all my pictures already loaded), specify that AVD for deployment, and start the application. I noticed a strange behavior. At first, the images are not loaded; the getView method is never called, although the constructor of my adapter is called. If I close the application, and open the Gallery app that comes pre-installed, I see that the sd card folder has the correct number of images, and it 'displays' the first four. If I start my application again, those four images are displayed, and only those. If I go back to the Gallery application, open the sd card folder so that it loads all images, and restart my application, all images are successfully displayed. Any reason why this happens? I am using version 1.6, and (part of) my code is below: Code...

I am developing an app that I wish to have pre-loaded with product images.Currently, I am accessing them from the resources folder 'drawable'. However, I also want the user to be able to add to list of products later by retrieving product information and products from a web server.
I can't access the resources folder at run time to save the images, so I need to have a single place to store them and retrieve them later.I have tried saving to the application directory, but am not having much success.I believe that storing images in the database is not considered good practice.

I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

I'm trying to load/reference images from the app's assets folder from within a HTML page in a WebView. Unlike in most of the examples the HTML page itself is not located in the assets folder but is loaded from a server via http. The background of this question are some performance improvements which should reduce the loading time (and the amount of transferred data) by loading static images directly from the device. I'm not sure if Android has some restrictions here because there's a certain possibility to exploit the app by allowing access to the local file storage from a remotely loaded webpage.

How do I load the image dynamically through the code? If its unclear, I mean, I want to load image files by name based on the condition in the code. If I use images as resources, the image names have to be hard coded. This is unacceptable to me. If I load image in a webview (with image src path dynamically), the time it takes to load is unacceptable to me. Can anyone suggest any other way to load the images dynamically?

I am creating an alternative keyboard. In order to help users understand how to set up the IME after it is installed I have added a simple Main Activity that appears in the Application Launcher with set up and usage instructions. I also have a preferences Activity and I want the user to have an option to hide or show the setup instructions Activity if they don't want to see it any more. My question is how best I can do this? I am assuming if it is possible it would require overriding the IntentFilter for the setup instruction Activity. I have experimented with this and read through the Intents and IntentFilter documentation but I can't see how to do this.

I noticed today that the "downloads" section within Market no longer shows any of the free apps that I downloaded-only the two apps that I paid for are shown. Does anyone else have this issue? Is there a way to bring this list back? A soft reset did not help.

Let's say, there are four apps in the system: app1, app2, app3, app4.
Be default, when the system is up, all apps will be shown in the home screen. Now if we provide a customized log in screen, user A log in, then for this user, he can only see (and use ) app1 and app2. Then A log out, user B log in, he can only see app3 and app4.
Does API provide such capability to load the app list dynamically?

I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...

When we create a new activity, in the Android.manifest file, we can set some text for the activity's label. It looks like:
<activity class="MyActivity" android:label="Some text here!">
Is there anyway to access that programatically and change it during runtime? Regards Dileep

I've got an activity for which I've defined an intent filter statically in AndroidManifest.xml. I'd like to register additional intents dynamically to that same intent filter in the activity's onStart() method. Is this possible? I'm trying to avoid having to implement a separate intent receiver class.

I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).
The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.
I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

I am writing an app that requires you to be logged in to a service before using it. From my understanding of android so far, you have to choose which activity to launch when you open from the launcher in the manifest. I don't know which activity i want to launch at compile time. I want the user to click the icon, then I check and see if they're logged in, then decide based on that whether to launch the login activity, or the main app activity. Is there a way to do this?

I have a use case in my application, where after certain point, I need to associate an data with an activity. So whenever an intent with an action and the data type is fired, my activity can be opened. I know that it is possible to associate a data type with an activity statically via AndroidManifest.xml.
Is it possible to register the data type for an activity dynamically and programatically?

When views with different type have same id and screen orientation changes,
either java.lang.ClassCastException: android.view.AbsSavedState$1 or java.lang.IllegalArgumentException: Wrong state class -- expecting View State will occur. (depends on the view's order)
Because View.dispatchRestoreInstanceState() checks id only.
You may wonder why anyone would make views with different type to have same id.
But it can happen when you use tab activity.
Imagine you have tab activity with two children activity.
Tab1 is ListActivity and Tab2 is ExpandableListActivity.
Both activity have id of "@android:id/list" but the type of view is different.
This means we cannot use ListActivity & ExpandableListActivit at the same in one tab activity.
