Android :: Search Engine App In Perst 4.0 Embedded Database?
Jan 26, 2009
Looking for a way to integrate full-text search and fast, lightweight data management with your Android applications? The new Perst 4.0 open source, object-oriented embedded database system brings native full-text search capability to Android and builds on this feature to provide a sample search engine application for contact data residing on mobile phones.
To provide search, the database stores an inverse index of keywords, with parsing and stemming of indexed text performed either by user- defined code or by Perst's default simple parser and stemmer. The feature supports logical operators and calculates relevance of search results to a query. The new sample application, ContactsIndex, stores and indexes contact information, and could be extended to provide search capabilities for PDF, word processing, HTML and other stored files. The example applications are included with complete source code in the Perst 4.0 for Java distribution..............

I have an ActivityGroup with an embedded TabActivity and another simple Activity.
The TabActivity has three tabs, each one with a ListActivity.
When I try to start a search from a list (calling onSearchRequested()), I get a WindowManager$BadTokenException.
I've tried requesting focus in the list, but the same error occurred.

How do you improve the position of an app in Android Market search results? The apps don't seem to be sorted on downloads.
The scope of this question is limited to working with the Android Marker search engine, of which there's little or no information. I changed the title to make it clearer.

I would like to write a client application for Android that uses the Google App Engine as a database backend. My Android client would connect to the App Engine to save information, then it would connect later for reports. Is it possible to use the App Engine as a backend like this?

I have implemented the search functionality using the android search dialog.to search multiple columns of a table using LIKE query.But search became slow as I have written a query in such a way that every time the text of each field(like the sample fields title,description category etc.) will be searched. title LIKE "---"OR description LIKE ''---"OR.....category LIKE "---"OR location LIKE"---"to. So is there any other way to speed up the functionality..

I'm playing around with an idea in the back of my head, was wondering if there were any Android devices that had touchscreen and wifi - no other requirements necessary. The GiiNii Movit Mini is as close to what I'm looking for as I can find. Are there hardware vendors that make custom Android products such as this? Inexpensive, ARM or MIPS, run Android, touchscreen, wifi, that's it.

Recently a client asked me to make their site "work on smart phones", which normally wouldn't be too much of an issue... However it's a video site, and I have absolutely no idea where to even begin. Right off the bat I'm not even going to consider allowing the site to even function in anything other than Android (Maybe even 2.0+) and iPhone, maybe Blackberry and WinMo. But beyond that... What do I do? I'm looking at using the tag, however I'm unsure what, if any, codecs which phone uses. Is HTML5 even adopted in their browsers yet?
Could someone please point me in the right direction? Am I going about this the right way, using the tag? Or is there some magical html element both iPhone and Android (And BB and WMo) that lets them run video in their native video players (Like on youtube).

I'm interested in developing an android application that will display a globe of some sort like Google Earth. I've never used opengl or have any experience with graphic programming so I'm here to learn some basics. Now, I know there are things like the Unity or Ogre that help facilitate graphics but what exactly do I gain from using these engines as opposed to just using opengl api to render graphics? Why do you use engines like Ogre as opposed to straight up opengl?

I'm playing around with some ideas and was wondering if anyone knew of an Android-based device that was basically a cell-phone with no screen.
Here's the requirements I'm looking for: - Support GSM - Single SIM slot or eSIM (3G preferred but not required) - Support GPS - Support BlueTooth - Optionally have an accelerometer - No display (this is an embedded device) - Would be willing to provide my own packaging (raw boards would be ok) I've debated taking the guts out of old G1s for this project. But if there is a specific device that meets my needs all the better. If there's any Manufacturers out there that have Android phone "guts" available, let me know too.

In my TabActivity, there is a button. When the button is clicked, I want the child activity embedded in this TabActivity to be updated. I wrote the code like below, and just wonder whether it is a good practice.

I love using the Engadget app on my Desire to keep up with daily news, but no matter what I try I cannot watch the embedded videos within the stories.....
The ones that link to YouTube are fine as you can choose the browser or the YouTube app.
But their native videos don't play for me. I currently get the choice of viewing through double twist or streaming media player, both of which say "Sorry, this video cannot be played".
Anyone any idea what format these endgadget videos are in? And how I can get the engadget app to choose a player capable of playing them?

I have an application that uses the webview to load webpages so user can download media off them, but i get a crash when any sort of popup tries to show (eg from a select box or save password dialog) - the error is that for some reason the webview doesnt provide the new dialog with the application context (even though it as passed to the webview component when it was created).
Is there some method to use to supply the application context to dialogs launched from the webview?

I am using embedded-linux for device which has Arch ARMv5 Speed 266MHZ, vfpu and 32bit bus, 32MB 133 Mhz DDR Ram. can you tell me which windowing system should I use,
1).QT for embedded linux
2). Android.
3). Other!
Well, I am using microwindows for last one year and not satisfied with it as it does not have BSP (Binary Space Partitionin) in its windowing system , No shared memory support for bitmaps. I think Microwindows is just optimized for memory-size not for speed.

I've been working for the past couple of days to allow users to login to an android app with their gmail account and pass the authentication token to my app hosted on app engine - so i can download xml from my web services hosted on app engine as if the user logged into the app directly. There is a lot of info on ways to get the google auth code and the auth cookie and then pass the cookie in the header of an http request - but no info out there on doing all of this from android and going as far as to add the cookie to the remaining http requests. So, now that's it's working, i thought i'd compile it all together and post the solution here in my blog - enjoy.

Can YouTube videos be played from within an AndroidOS without launching the separate YouTube player? How about WebOS or Blackberry? On the iPhone I can do this with a WebView and the embedded YouTube code and I'm weighing the possibility of porting my app to other mobile platforms.

I've started working on some Android applications and have a question regarding how people normally deal with situations where you have a static data set and have an application where that data is needed in memory as one of the standard java collections or as an array.
In my current specific issue i have a spreadsheet with some pre-calculated data. It consists of ~100 rows and 3 columns. 1 Column is a string, 1 column is a float, 1 column is an integer. I need access to this data as an array in java.
It seems like i could:
1) Encode in XML - This would be cpu intensive to decode in my experience.
2) build into SQLite database - seems like a lot of overhead for static access to data i only need array style access to in ram.
3) Build into binary blob and read in. (never done this in java, i miss void *)
4) Build a python script to take the CSV version of my data and spit out a java function that adds the values to my desired structure with hard coded values.
5) Store a string array via androids resource mechanism and compute the other 2 columns on application load. In my case the computation would require a lot of calls to Math.log, Math.pow and Math.floor which i'd rather not have to do for load time and battery usage reasons.
I mostly work in low power embedded applications in C and as such #4 is what i'm used to doing in these situations.
It just seems like it should be far easier to gain access to static data structures in java/android.
Perhaps I'm just being too battery usage conscious and in my single case i imagine the answer is that it doesn't matter much, but if every application took that stance it could begin to matter.
