Autocomplete TextView populate from server in android

Question

I need to fetch data from server and populate in autocompleteTextView in android. I have used a custom filter for the same where I fetch in onPerformFiltering() and display in onPublishResults(). But I need not fetch data from the server for every character Change.I need to do it for specific length of characters. How can I do this?

You can make use of JSON, HttpRequest. Check my answer http://stackoverflow.com/questions/8653260/autocomplete-in-android-not-working-with-dynamic-data/9451022#9451022 In this example i have used Wikipedia Suggest API. — Raghav, Jun 22 '12 at 16:47
Thank you so much that works like a charm:) Can i use any other api instead of wikipedia suggest api in the same way. — O__O, Jun 23 '12 at 03:05
Yup you can use any other API, you need to configure little bit to work :) since JSON structure would be changed from one API to another. — Raghav, Jun 23 '12 at 05:16
I some times get this error and the application force closes: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. — O__O, Jun 23 '12 at 15:46
Well android want views to be be edited by UI thread only, background threads cannot update views directly, you need to use runOnUiThread() for this. — Raghav, Jun 23 '12 at 15:49
I have done it this way only. Even then it crashes sometimes..:( — O__O, Jun 23 '12 at 15:56
@androiddeveloper [Here](http://stackoverflow.com/questions/5023645/how-do-i-use-autocompletetextview-and-populate-it-with-data-from-a-web-api) is an answer for a very similar question. I recommend using the getFilter function, with that you save the time of handling asynctasks, that runs the query on a background thread and then updates the list on the UI thread. — Aldo Reyes, Jul 29 '12 at 18:41
