In one activity I build a cursor which is used to populate a ListView. I want a secondary activity to be able to step through the cursor entries. What's the best way to do this (bearing in mind cursor lifecycle). I don't care if the the system kills and restarts the secondary activity since in that case the stepping through entries functionality could be temporarily automatically disabled.

I managed to create a secondary Activity, but now I wonder how I can close it again.
public void button_onClick(View v){
finish();
}
works when I'm dealing with just one Activity at a time, but how do I let the secondary Activity close the entire application?
I need to support Android 1.5 (Cupcake) for my application but I don't have any 1.5 device. I currently have a Motorola Droid with 2.0.1 and the T-Mobile G1 (HTC Dream) with 1.6 (Donut).
What I want to do is to downgrade my G1 to the previous official OTA release of Cupcake. I have no experience in rooting an Android device, so I would appreciate if someone could give me a step by step guide on how to accomplish this?
Can you please share a good Android tutorial with step by step basic programs.

View 4 Replies View RelatedOn Youtube, there is a user named thenewboston who posts videos teaching basic computer programming that are aimed at total beginners like me. His tutorials are really easy to understand, because he goes through the process as if talking to an elementary school kid.nyway, he just started a tutorial series about developing iPhone apps. Maybe it's time someone from the Android camp did the same? Sure, there are many tutorials already available online, but they don't appeal to the common person, and the good video tutorials on Youtube are all more than one hour long. By doing something like this, more people would be attracted to try develop apps for Android.

Is there some way to save the cursor's state/location when the activity is paused or stopped so that when the activity resumes the cursor is restored and in the same position as it was when the activity was paused/stopped?
I fould this online and thought it may come in handy for some people 1. Benefits The CPU drains more power if it is running at a higher frequency. If the processor is running faster, the phone will be faster and more responsive, but the battery may drain more quickly. If the processor is running more slowly, the phone will be less responsive and take longer to complete tasks, but battery life will be increased. With SetCPU, you can set up profiles to manage the CPU speed based on certain conditions.2. Main Tab and Basic Usage To get started with SetCPU, start the app, read the introduction, and pick "autodetect frequencies." If you ever need to access this screen again, press the Menu button in SetCPU's Main tab, then choose Device Selection.If your kernel doesn't support autodetect, you won't see it choose the device that best matches your phone from the list. After you've passed the introduction screen, you may get a request from Superuser Permissions. Depending on your version of Superuser Permissions, either check the box for "remember" and press "allow" or press the "always allow" button. The sliders here allow you to manually control the CPU scaling bounds. The CPU frequency will always be between these two values. By default, the CPU should scale between the max and min frequencies based on need. The sliders also control the "main" profile as explained later. The "scaling" drop-down list is an advanced feature that allows you to control the behavior of the CPU scaling mechanism. See explanations for the different governors in the CPU Scaling Governors section.SetCPU also includes a widget for your home screen. Add SetCPU's widget like you would any other widget: long press on your home screen, select Widgets, and select the SetCPU widget. A screen will pop up so you can configure the widget's appearance. If you would like it to show current CPU speed, set the Active Refresh Interval to something other than "Passive," though a passive refresh interval is recommended to save battery.

View 1 Replies View RelatedThe structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.

View 3 Replies View RelatedI get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.
How do I merge these two informations?
I am looking after an alternative way now. As what I ideally want is:
Get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it's not possible with CursorJoiner) but there is more, if the join is not unique I want to sort by contact's name as last measure
Which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList
Also this translated to TSQL it would look like
select * from contactsdata
left join category on contactsdata.catid=category.id
order by category.pos asc, contact.display_name asc
So I am looking now after an alternative. I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?

View 1 Replies View RelatedThis just occurred to me today and it would be really nice. I've bought a few apps I no longer want/need and would be willing to sell them to someone else at a discount to recoup some of my loss.Any thoughts on this? I think it would need to be an update to the android market to have an option to 'transfer' to another user so updates for the app would show up in the market. You could keep the developers happy by giving them an option to make their apps eligible for this or not.I suppose this would only be feasible for apps that are also the type that are private and can't be backed up to the SD card with something like Astro File Manager.
