I know that network activity and expensive operations should not be done on the ui thread, but what about database activity?
I have an activity that, when started, I query an sqlite database and dynamically populate rows in a tablelayout with an inflator. I do this all in the oncreate() method. Should this be done in a separate thread?

Would be interesting to know what applications you use at work. In Sweden, we can not get pay apps yet so it must be "free"

1- I am an iphone application developer, all iphones have very similar Operating systems, and the size and everything is the same, so I don't need to create applications specific for each iphone.
But with android there are different phones, different sizes, So How can i possibly know that my app works, and looks fine on all these devices
2- I don't already own an android but i completed my first application using the simulator. Which android phone do u suggest for testing? I am an AT&T user and i use an iphone. Can i simply insert my sim-card in the new android to be able to test my app on the device?

I am new to Android, and I haven't developed any app regarding databases on Android yet. So I have a few basic questions. I am after a good database class sample, that will let me to run the CRUD operations. I would like to use it as a static class
like: clsDB->Select("select * from clients");
or objClient->Delete(clientid);
I am wondering if someone, can share his database classes, if more people share the best. Also I have in mind to reuse this class in multiple ways, I will have services, activities etc...

I'm working on an app, and one activity has a worker thread that initiates a database query, and if there are results once it has returned I would like to send these results to a new activity that will display them. Unfortunately I don't see a way to pack the Cursor object into the Intent object that I am using to start the new activity. When I was doing Windows Mobile development in the past all I would do is edit the constructor for the window to pass in the data, I've searched around but I can't find a similar solution for Android. What is the best way to pass my database results into the new activity?

Since previous releases of android SDK (I think since version 0.9), I have a warning when I run a aplication from Eclipse.
"Warning once: This application, or a library it uses, is using NSQuickDrawView, which has been deprecated. Apps should cease use of QuickDraw and move to Quartz."
How I can solve this? I am running Eclipse 3.4 (Ganymede) in Mac OS X 10.5.6.

I'm trying to deploy an application with an existing SQLite database.I've been reading though the examples that are posted but they are always missing some part of the class. I feel like I'm trying to bake muffins but no one told me to use baking powder.Can someone post a full database helper class for depoying an SQLite database on Android? Edit : Delete old code because it doesn't work.

I'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?

Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.

I want to be able to show the Battery Info activity in my app, which shows things such as the exact level, battery health, etc.I'm not sure how I can get it, though a few applications such as Power Manager, Any Cut, etc. show this screen as well. I found in the source code of Settings this intent in a file called testing_settings.xml,But I don't know how to use it. I would guess from the fact that Any Cut has a list of activities, that a list of said activities exists somewhere, and therefore an easy way to access them exists, but I haven't found it.

My app is comprised of a set of reusable Activities that other apps can reuse. For various reasons, I would like my Activities to be launched in context of the invoking Activity's process, instead of always being launched in my Activity's process (default behavior on Android). How can I achieve this?

So I have an app with Activity A. The layout on the activity is dynamic genearted. So it's possible that on Activity A a user hits a button that goes to "A" and the new page looks different, then a user clicks another button to go to "A" again. Now I have 2 Activities in the history stack. A, A, and currently on A. Is it possible that if a user clicks a button that the whole Activity stack is cleared in a scenario such as this?

How can I make sure I only retain one copy of an activity on the stack when called from non-activity? When called from an activity I can just add the FLAG_ACTIVITY_REORDER_TO_FRONT flag to the Intent, but how can I do this from e.g. a widget or a notification?

I have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method.
In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process.
However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate->onResume->onPause->onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment.

Im writing a program that offers a quick reply dialog upon receipt of an SMS.
However, I am getting an unexpected result. When I receieve an SMS, the appropriate dialog activity comes up displaying the correct phone number and message, however there is a second activity behind it that is the 'default' activity in my program (it is what opens when i launch my application)
I do not want this second activity to come up. The quick reply activity should come up by itself over top of whatever the user was doing before.
The 'floating' activity:
CODE:.........
The call to the activity inside an onReceive()
CODE:..............
The Manifest:

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing.For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits.I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this?

I'm working on an app that launches the browser activity to perform a Twitter OAuth authorization. This process uses a callback url which will re-launch the activity that started the browser activity in the first place.My problem is that the browser pages remain in the history stack and when the user then clicks back from the preferences activity that launched the browser in the first place, they don't go back to the app's main activity, but instead are brought back to the browser. I've tried adding flags to the launching intent to prevent history and reset on clear, but it doesn't seem to work when running on my phone, only on the emulators.
