Android :: Developing One Application - Getting Exception?
Sep 9, 2010
I am developing one application in which i am getting an exception, and i know this one is the silly or small mistake which i am doing but your help may catch me out and make my day:
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:
Update:- 2
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.

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.

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?

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.

Unhandled exception will force close the app. How to collect these exception in the app? It is better if the user has a choice send these messages back to the developer to improve the app.

When I add the following line to my GLSurfaceView class I get an IllegalArgumentException from some random place. I don't know where the problem is because it doesn't give a stack trace. set EGLContext Client Version(2); What else do I need to do to get an OpenGL ES 2.0 application to work? I have tested this with a completely empty renderer class (and also put breakpoints on every callback, and none of them get hit, indicating that the error occurs before my renderer even gets involved). Does anyone have a complete working example of how to get started with Android OpenGL ES 2.0 development? [There is also a stackoverflow entry here -> http://stackoverflow.com/questions/3026368/illegalargumentexception-w]

I'm trying to call a RESTful web service from an Android application using the following method:
CODE:................
I can browse to address and see the xml results using the Android Emulator browser and from my machine. I have given my app the INTERNET permission.
I'm developing with eclipse.
I've seen it mentioned that I might need to configure a proxy but since the web service i'm calling is on port 80 this shouldn't matter should it? I can call the method with the browser.

When my app loads, I fill my android.app.Application with some data. The app runs fine as I use it and all the data is available. However, when I leave the app over night and look at it again the next day, I receive NullPointerExceptions when attempting to use that same data. I do not believe Application objects get garbage collected, so I have no idea what is going on? I also lose static objects in classes used by my Activity classes. I am on Froyo 2.2 on a Google Nexus One. Looks like someone else had a similiar issue: http://groups.google.com/group/android-developers/browse_thread/threa...

I'm trying to do a simple global exception handler in my Android app and I am having troubles:
public class TicTacToe extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread.currentThread().setUncaughtExceptionHandler(new UncaughtExceptionHandler() {
@Override
public void uncaughtException(Thread thread, Throwable ex) {
Toast.makeText(this, "TOAST", Toast.LENGTH_LONG);
} } );
setContentView(R.layout.main);
} }
I'm a rather new with both Android and Java but in .NET that would work. Can't I access local variable from anonymous methods in Java? If so, how should I rewrite it?

I am trying to develop soft keyboard in my language, Amharic (Ethiopian language). I start developing the soft keyboard by using the sample soft keyboard with is included in the android SDK. But I have the following questions to ask:
1. How can I include keyboard setting options such as vibrate on key press, sound on key press, etc. such setting options are available in English soft keyboard. If you have any idea about this, please help me.
2. The other question is related to copyright issue. If I can succeed in developing the keyboard and want to sell it in market, am I going to violate the copyright law? Because I have developed this application by using the sample soft keyboard.
