I am currently learning to develop Android applications, and to do this I have decided to develop a dictionary application. The UI, and search facilities are no problem to implement, but my question is, what is the best way to store the entries and definitions for the dictionary? Would XML be the best approach? I would be looking to include 500 - 1000 entries.

CODE:.......
In above code, if i make i=0 or i=1 in tryDemo function then it is running successfully , but if i make it other than 0 or 1 then it throws an exception as "Demo - Demo Exception".
I am not sure but i think the exception raises from getApplicationContext().
Update:- 1
The exception which i am getting, as follows:

If I remove the "thread" part and wrote the whole function code in the button click event and replaced the "getApplicationContext()" with v.getContext() then it is running successfully.........but i want to implement it within the THREAD.

View 3 Replies View RelatedI want to develop application that should support all version (latest and old) and it should adjust screen resolution (large,medium). I read document. There I found legacy application if I develop application in 1.6 there I am giving:
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/>
Is it good way to develop application and is it support 1.5 and 1.5+. Users able to find my application there market.
I want to develop UI of the application which looks similar on all screen sizes. I have gone through the Android developer article regarding this. I am using supports-screen tag but then also the screen is displayed not displayed properly in the larger screens. The screen is displayed properly in HVGA and not in WVGA.
I have developed the application using Android 1.6 and set the minimum SDK version as 4. The application is running properly on HVGA avd but not on WVGA avd. Can I know the reason for it? Is there any solution for this? I want that the user interface of the application should look uniform in all the handsets.
More and more mobile platforms are being launched and sdk's are available to developers. There are various mobile platform are available,Android,iOS,Moblin,Windows mobile 7,RIM,symbian,bada,maemo etc.
And making of corss platform application is headache for developers. I am searching common thing across the platforms which will help to developers who want to port application to all platforms.Like what is the diff screen resolution, input methods, open gl support etc. please share details that you know for the any of platform . or is there possibilities , by writing code in html (widget type of thing) and load it into native application. I know about the android , in which we can add the web view into application. by calling setContentView(view)
Please share the class details where we can add the html view into native application of different type of platforms that you know.
Purpose of this thread is share common details across developers. marking as community wiki.

I'm making an ecommerce application on Android and, as it is my first serious project, I'm trying to figure out beforehand the best approach to do this.The application talks to a web service (magento api, meaning soap or xml rpc unfortunately) and gets all the content on the phone (product categories, product details, user credentials etc.). I think it should do lazy loading or something like that.
So, I was thinking to keep the user credentials in a custom Object which will be kept in a SharedPreferences so that every Activity cand easily access it. I'll use a couple of ListViews to show the content and AsyncTask to fetch the data needed. Should I keep all the data in memory in objects or should I use some sort of cache or a local database? Also, I'm planning to use a HashMap with SoftReferences to hold the bitmaps I am downloading. But wouldn't this eat a lot of memory?How cand all the activities have access to all these objects (ecommerce basket etc.)? I'm thinking of passing them using Intents but this doesn't seem right to me. Can SharedPreferences be used for a lot of objects and are there any concurrency issues?
Any pointers would be really appreciated. What are some good guidelines? What classes should I look into? Do you know of any resources on the Internet for me to check out?
I want to write an dictionary application for Android. I want it offline with at least 5000 words. My questions are:
What should I use to store my words, I mean is it a good idea to create an ArrayList, hashmap etc? If not then why and what do you propose? The more important thing for me this this how to create a database to store the words which will be at least 5000 I want the apps to work fast and work offline no need of network.
First of all, I just want to say I am a software developer, but I am not an Android developer. However I usually walk around and think on stuff. AndI've been recently thinking all the news concerning how fragmented Android is getting, with different Android versions and tweaks by different phone manufacturers, and then for developers you have different size formats. An example would be that HTC Tattoo might not be able to run everything that another phone might run, due to different screen formats, etc. And now the Android tablets are coming with different Android versions and different screen sizes, all from 5" to 11". Will this make developing Android applications harder? Apple has it safe here since they manufacturer all devices that run the iPhone OS: the pods, phones and now the pad so they can easily control and make sure not to loose any customers by introducing a new device. When Apple introduced iPad they had to make sure that all the old iPhone applications would work on the iPad. They solved that neatly by saying that iPhone applications will simply be stretched out to the double size and it would fit on the iPad. Unfortunately Android does not have the same luxury to do this. As I said, I am not an Android developer. Just a curious software developer For you guys who work actively in the Android community, does Google have a solution for this? Will you be able to run phone applications on the tablets? Is there a bridge between the devices? Are there any standardizations or will Android development become even more fragmented? you are subscribed to the Google Groups "Android Developers" group.

I have a couple of apps working using eclipse and the emulator. I now want to try the apps on my htc aria. I went through downloading the usb driver as the Android Developers documentations sans and a usb driver folder now shows up in my sdk folder. However, apparently there isn't a driver for the HTC aria in the folder.
After research some people suggested using htc sync. I donwloaded htc sync and let windows check that I had the latest version. However, my phone keeps saying that it can't find htc sync on my computer.
When I plug in my HTC aria, the device manager on my lap top recognizes two devices as listed below: My HTc under Android USB devices and a HTC Android Phone USB Device. I clicked on update driver for both devices, Windows found them on-line and verified that they were the latest. I dont understand why there are two drivers, but My HT seems to have a problem as listed below. One thing that I should mention is that I am using the dreaded VISTA.
Device Manager: Android USB Devices: My HTC Device status: Windows cannot initialize the device driver for this hardware. (Code 37) Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available.
Description: Windows was able to successfully install device driver software, but the driver software encountered a problem when it tried to run. The problem code is 37.
Problem signature: Problem Event Name:
CODE:.................
HTC Android Phone USB Device
Device Status: This device is working normally. Driver Provider: Microsoft Driver Date: 6/21/2006
So, the best I can tell is that there isn't a driver from the normal Android repository for the htc aria yet. And, for some reason my computer can't handle the htc sync drivers.
Will there be a usb driver for the htc aria that I can download from Android Developers in the future? Has anyone else been able to get htc sync to work with the htc aria? Is there anohter way to transfer my apps to the phone for development?
I guess that I can always use the ddms environment and transfer the app, but I really wanted a more graceful way to do this.
If it's possible to develop on an android device or if it will happen anytime soon?
View 6 Replies View RelatedI am working on an app that has a homescreen. This homescreen should behave like the android homescreen where you can switch between several views by flinging your finger over the touch screen.
The solution is easy. I have 3 view instances, right, left and current view. I get this instances from the viewflipper that I initialized earlier. Since I have a HTC G1 my sreen is 320 px in width and 480 px in height.
Imagine you capture the down value of a action down motion event when you touch the screen. Then you move your finger and the screen should move in exactly the same way so you have to recalculate the view's position. It works for me so far but I am facing a strange problem. When you touch the right view without moving you finger but keeping it on the screen for less then a second the view disappears and shows the left view.
Here is my code:..........................
I think such a Homescreen for your own app could be a interestion UI element.

View 4 Replies View Relatedis it viable to develop applications using a stock T-Mobile G1? I guess in contrast to the emulator the real thing is restricted when it comes to debugging.But, is there a simple way to just transfer my self developed, self compiled APK to the phone and install it there? I do not have to go through the market for that, do I? :) Then again I guess it's not as easy as with the emulator, just clicking "Run" in Eclipse - or is there a way to tell Ecllipse to transfer the freshly compiled software to the *locked* phone?Yes, I know I could get an unlocked Dev Phone 1, but, my question is whether this would be *required* or, if not, what my options as a developer are when working with a stock, locked, phone.
View 5 Replies View RelatedI am a student at a technical university in Finland, and Im currently working on a thesis about how suitable Android platform is for multimedia devices other than smartphones or mobile handsets. Different manufacturers have been experimenting with Android for a while now, and have installed the platform onto new types of devices such as mobile internet devices (Archos 5), tablets (Vega), and even e-book readers (Barnes & Noble nook). Almost all of these manufacturers are also welcoming Android developers to create applications to go with their devices. Compared to the number of applications on Android Market, however, the manufacturers are still very much in the beginning stages with this. I�m hoping to have some idea about what Android developer communities are thinking about this invitation, and so decided to post a poll about it on a few Android forums. Are you interested in developing applications for these kinds of devices, with larger screens and different capabilities from an average mobile phone? If it�s not too much trouble, I�d also be interested in hearing a few words about why you think it would be a good or bad idea. How would it be different from developing for phones? What sort of problems or possibilities do you think would rise from it?
