I'm trying to display an image using a URL. When I run the code I get an error telling me the application has stopped unexpectedly. Can anyone see what's wrong in my code.
Bitmap bmImg; URL myFileUrl =null; try {
myFileUrl= new URL("http://www.starling-fitness.com/wp-content/ 240384vBdA_w.jpg");
} catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace();
} try { URLConnection conn= (URLConnection)myFileUrl.openConnection();
conn.setDoInput(true); conn.connect(); int length = conn.getContentLength();
int[] bitmapData = new int[length]; byte[] bitmapData2 = new byte[length];
InputStream is = conn.getInputStream(); bmImg = BitmapFactory.decodeStream(is);
/*timetableImage.setImageBitmap(bmImg);*/ setContentView(R.layout.timetable);
ImageView iv = (ImageView)findViewById(R.id.timetableImage); iv.setImageBitmap(bmImg);
} catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace();
}
We are looking to create a device that only shows/gets information from one source on the internet. There will be only one application running on the device.

View 1 Replies View RelatedI have an app which uses a large amount of data which has been compiled outside the app (on my main PC). The app is for my personal use so there are no complications with having to distribute data updates to other users. However, I am currently following a very convoluted and time-consuming procedure each time I want to update the data, and I wonder if anyone can suggest any ways to streamline it.
The procedure I follow whenever I want to add new data is as follows:
I enter the new data into a csv file which I maintain as the source of the relevant table in the database. I use SQLite Database Browser to import the data into an existing SQLite database. (This program does not seem to have the ability to append imported data into an existing table, so whenever a table needs updating I have to delete the existing table, then import data from the csv file into a new table, then manually edit the data types for all the fields in the table.)
I drag the icon for the database file onto the 'assets' folder of my project in Eclipse. I export the project from Eclipse as an apk file. I copy the apk file to my phone (using Astro File Manager) I uninstall the old version of the app and install the new apk.
when the app is run, code based on the example set out here copies the data from the 'assets' folder into the app's data folder; this means that each byte of data takes up two bytes in the phone's internal memory; at present this is not a problem, but could be as the volume of data grows; I wonder if there is a more memory-efficient method?
i want to ask about that can we convert the input source type data in android. my prob is here that i get the data from the url not in tags form. i fetch output in the inputsource type. after that i want to parse the data in meaningful form is this possible or not? if this possible then how can i implement?

I am having a weird issue. I have an ArrayAdapter which I am sorting. This displays properly on my screen, however when I check the actual data source, the contents have not been sorted. How can I ensure that sorting my ListAdapter will also sort my data source?
CODE:....
This shows that my data source hasn't been updated, even though my ListAdapter presents my ListView in the correctly sorted order.
For example:
If my data source is [10,9,1,20] after sorting my ListView will show [1,9,10,20] but the data source will still be [10,9,1,20]

I have an app in which there are several requests to a server in internet (http), for example to retrieve images in threads outside the main UI process. The thing is that I have a Thread that manage the request with a while(!end) loop and in the end a Thread.sleep(500) that checks if there are new unhandled requests. As I read here [1] I know that this is not a good practice. And users have complain about ANR (app not responding) in several cases.
Knowing that obviously I want to refactor all the way my app manage the requests and I want to do that the best way. So, the question is; what is the best approach for doing this? A service? a broadcast receiver and send intents when I need a request to be handled?
How could I create a ContentProvider where the data is fetch from the internet. As the data is parsed maybe allow the requesting client know the download progress and results so that they are displayed as it's downloaded. My idea is to share this data across other apps. I'm not sure if a ContentProvider would be the solution?
View 4 Replies View RelatedMy app needs to send some data to a server when the device is connected. I have been reading about native Android Broadcast actions. I was willing to find a way to use one as gmail does when the device connects to the Internet. (The "loading" icon on the top while it syncs mails) Is it ACTION_SYNC what I am looking for? If not, how does gmail knows when the device connects to internet?

View 4 Replies View RelatedI have here a function that downloads data from a remote server to file. I am still not confident with my code. My question is, what if while reading the stream and saving the data to a file and suddenly I was disconnected in the internet, will these catch exceptions below can really catch that kind of incident? If not, can you suggest how to handle this kind of incident?
I call this function in a thread so that the UI won't be blocked.

my application is not a service, it's a normal application, with some windows and some stuff. i dont wanna make it a service cos is too munch complicated and i prefeer to avoid it then, if my application is not a service, when it goes to background (home key pressed for example), it continues working (sending/getting data from internet)? i ask this because i read this on a developer guide tutorial: "Because an Activity can perform actions only while it is active and in focus, you should create your status bar notifications from a Service"

For this i am using AsyncTask -
code for AsyncTask is as follows--
CODE:..........
And calling this code as follows--
CODE:...........
But ProgressDialog is not shown.(I guess the reason for it is the thread is not complete and android invalidate only when thread has completed).
My Questions-
1- If my guess is right ? If yes then how I should implement it?
2- If there is any other better way to do this?

I've had a Hero for a few weeks now, and while most things are great, I'm finding the internet connection very unreliable. For example, if I try to use the browser to view a website, often it says it can't find the page, even for www.google.com, and this is using a bookmark so I know it's a valid address. Often in the Market, it says it doesn't have a connection and to retry or cancel.
I am usually connected via wi-fi, either at home or at the office, so I know the wi-fi connection is good, and both have been tested thoroughly with my iPhone 3G. It's almost as if I have to wait for something to happen before I can use the net, but I make sure the wifi signal symbol appears before I try anything. Why could my data connection be so unstable?
