Using Local XML file as a database for a android app?
I am trying to build a app with flash using a xml file as database, to read the xml from a external file from the local directory isn't a problem, the problem is how to write data from flash to the xml file.

I am working on a project for a belgium Tv Guide. Now I download a database (.db) file from a server to the sdcard to work with. In this database are 2 tabels, tvchannels and tvprograms. Now I can do several updates to the tvchannels table and i want to make a backup of this table to a lokal database file. How can i do that? I want to do this because I have to download a new database file every daye from the server and the channels that are choses are saved in the tvchannels database. I want to backup this database table and when the new database file (tvgids.db) is downloaded I want to replace the tvchannels database (from downloaded database file) with the backup from tvchannels..

View 1 Replies View RelatedI published an application that stores data in a local database.
Now I have to publish an update to this application to fix some little bugs, but I am afraid that downloading and installing the update will delate the local database associated with the previous version.
I would like to know how the update system works. Will installing an update completely delete all the apk, files, databases associeted with the previous version?
If so, how can I avoid this in my code?

View 7 Replies View RelatedAll of the android examples for XmlPullParser pull from a local resource file, and all of the SAX examples pull the XML from a URL. I've been told SAX is faster, so I'm trying to use that to pull data from a local resource file (res/xml/thefile.xml)
The example code I'm working off of is here. So in that example, the code I want to change is:
URL url = new URL("http://example.com/example.xml");
...
xr.parse(new InputSource(url.openStream()));
Instead of using URL, I want to use getXml(R.xml.thefile)
Is that possible, or does SAX need to get data from a URL?
I'm trying to get a byte array of an image saved locally on the phone. I'm using the code...

I don't want to store said file on the sdcard in this case. The file also cannot be storage directly in the apps local files directory. It needs to be in a subdirectory, so it cannot write the file using openFileOutput() and MODE_WORLD_READABLE.
The app may download files small files like pdfs and store them locally in a subdirectory. I would like to be able to have the user open these files if they have an app that can open them.
For example here is an intent for sending a pdf:
CODE:..............
path being something like: /data/data/packagename/files/subdir/example.pdf
That intent will open a pdf viewer, but the viewer is unable to open the file. I assume this is a permissions issue. I tried Mark Murphy's suggestion here: http://groups.google.com/group/android-developers/browse_thread/thread/4e55d869213483a9/b7270078ac1a2744?lnk=raot of using Runtime.getRuntime().exec("chmod 755 " + fileName); but it didn't make any difference. He also suggested a Content Provider but I would like to avoid it if I can because it seems like a lot just to get this file over to another app.
If the content provider is the only option, do I have to save the file to the content provider or can I just use the content provider as a pass through to get it to the other app when I need to?
I thought it might be interesting to some developers. Here's a complete working example of ContentProvider for this purpose: http://blog.tourizo.com/2009/02/how-to-display-local-file-in-android. I also found a topic here: http://groups.google.com/group/android-developers/browse_thread/threa. Looks like the topic was closed and I couldn't reply there, so I created new one.

I am trying to get googlemaps to accept a local KML file.
final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=file://" + Environment.getExternalStorageDirectory() + "/locate.kml"));
startActivity(myIntent);
The file is on the SD card, and is a valid KML file. Google Maps loads up, but says it cannot find the file.
final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=http://www.website.com/locate.kml"));
startActivity(myIntent);
Works fine. geo: 0,0? q= seems to be very under documented, how to use it to refer to a local file?

Uri data = Uri.parse("BattlestarGalactica.3gp"); intent.setDataAndType(data,"video/3gpp"); startActivity(intent);

View 1 Replies View RelatedWhen trying to play a local mp3 file included in the APK, nothing happens. However, if I pull an mp3 from the web it works.
e.g.
< a u d i o src="[URL]..." > WORKS
< a u d i o src="01.mp3" > DOES NOT WORK
I tried looking through logs for clues and found this line. I'm not sure if it's relevant or not.
PlayerDriver::isProtectedFile(file:///android_asset/www/01.mp3)
I'm new to Android development, so I can only guess that the file is somehow inaccessible for streaming.
I'd love to get this figured out though. Having to pull the files remotely every time is not a desirable solution.
Some additional info. Either solution works when tested in the browser. The local file problem only arises when I convert it to an app. I'm using PhoneGap build to create the APK.
I'm now trying to implement my own content provider. My original data was stored on network or local/remote file systems, so I want to provide data via input stream. I know that client may call ContentResolver.getnputStream to retrieve the input stream to access data. But I don't know how to implement content provider in this situation, I searched the Internet but all the tutorials for content provider are talks about how to expose data that stored on local database. how to expose data that stored on file systems using a content provider? what happened when client call ContentResolver.getnputStream? I want to know how to return an input stream to my client.
View 4 Replies View Relatedi just registered here to find out if opening a KML file on my SD card with Google maps in offline mode can work. I am looking for an solution quite a time, but only found this thread on stackover.
Quote:
To load kml into Google Maps on Android without writing an app, you can create a little html file somewhere with a geo-uri link to the kml file and then click on that link in any Android web browser.
For example: suppose your kml file is located in /sdcard/overlay.kml then you write a geo-uri link like this:
Quote:
<html>
<head><title>Example KML link page using a geo-uri</title></head>
<body>
<a href="geo:0,0?q=file:///sdcard/overlay.kml">overlay.kml</a>
</body>
</html>
Clicking on the link will launch Maps and then Maps will attempt to load and your kml.
Be warned however that the Android version of Maps does not appear to handle the same version/range of kml elements as the desktop version (or desktop Google Earth).
a other thread is about editing the manifest file to get maps to open local KML files
