Android :: Using Local Files - Overlay Route Data In KML Files On MapView?
Jun 11, 2010
I am trying to overlay route data in KML files on a MapView.
The following code works great:
The only problem I have with this is that I don't need to re download these KML files every time. I have about 10-15 KML files that will rarely change. Also since it has to connect, download, and parse these each time there is a delay in opening the maps.
It would make a lot more since for me to save these as a local resource and have the URI reference it there. Is there a way to construct a URI using the geo: scheme and have it point towards a local resource?
It looks like file:///sdcard support was included in 2.1. The only reference I could find to it was at the end of this bug report thread. I am currently at work and don't have time to play with this yet but I would like to figure it out later. I feel like there are a lot of people on stackoverflow and elsewhere who would really appreciate a reasonable way to do this.
"You can store files directly on the mobile device or on a removable storage medium. By default, other applications cannot access these files. "
I could write to the sdcard (/sdcard/file.tmp) and other apps could access these files, right?
I would like some local storage that I can write files to (and read from later) that are not accessible to other applications, and I will always have access to. The problem with the sdcard is that if someone plugs in a USB cable and turns on MSC, my application (and all applications on the phone) will lose (both read and write) access to the /sdcard directory. So I need something more reliable.
I 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?
Check out Mono. It takes a different approach by giving you access to all artists and their releases and then matching up content from either your local files, your files uploaded to Google Music or YouTube.
I want to create a simple Map based application in android ,where i can display my current position.Instead of overlaying a simple Image on the MapView to represent the position, i want to overlay the GLSurfaceView on the MapView.

I am looking for a way to overlay a route in google maps.
What I want is to take this map Greenways Oak Ridge Google map and get it to my google My Maps. Then I can pull it up in Maps and use my location to see where I am in relation to where I need to be in case I want to take a different route to need to shorted the ride due to darkness.
Most rides I do I can find these maps but cant do anything with them.
I am doing one small GPS application. I have to show multiple palces . I can able to show multiple places using custom overlay method.Now i have to show route between two points , while showing route i have to show only that two points. remaining all points should disappear but i don't know how to disappear the other points.
I wrote an app that downloads web sites and all their assets (images/stylesheets) to "disk" and therefore stores lots of small files on the SD card.
Sometimes it fails to delete large amounts of files and afterward the file system is r/o. To analyze that behavior I tried to do the removal of the files by hand and then go from there. But that already failed.

The log contained nothing but the usual gc output and random WiFi status changed mumbo jumbo.
Anybody else seeing this behavior?
There were 6.500 files in that directory. Might that be the problem? I don't access the files with queries, I always have the exact name.
I am working on an android app. Where i need to parse some plist files from assets folder. I do understand how to use assets in android but now problem is that file sizes are more than 1MB and so android gives error Data Exceeds UNCOMPRESS_DATA_MAX (2183588 vs 1048576). how to access such larger files from assets? Also I cant reduce a file into small buffers because i am just sending it to "DocumentBuilder.parse(in)" as a whole so can not use buffer. The error is on line: Document doc = db.parse(in).
I want to know how to get the ringtone,audio files in the device and I want set them as alarm. I am working in the code to set the alarm and I want to know how to retreive audio or ringtones from the device.
Sometimes I'm browsing the web and... One more download... And then oops! Another one...Then I realised that those downloads are still in my download list and there's no option to COMPLETELY remove them. Also, where do I clean browser's temporary files?
I have a Samsung Galaxy I7500 using android 1.5. I extended my phone with a 16GB microSD. I copied a big music collection (around 800 files) into a folder on this SD. Now the problem is that the music player can't find all the files.
I know that there are several threads about android not finding music. The answers are usually that the library hasn't yet been updated or that the ID3 tags are not correct. I have checked both.
Btw. I can play the files using ASTRO.
In my opinion it seems as if android can't build up a library with too many entries. If I rename the files or put them into different folders, songs disappear and reappear quite randomly.
Do you have any solutions? Is there a music player which doesn't use the native music players index of files?
I uploaded about 50 pictures from iPhoto (using a Mac) just to see what they looked like and then later formatted the Droid's SD card, so the pictures were no longer there.
Now, if I mount the Droid via USB and view the file structure there is a folder named /albumthumbs which contains 50 files, presumably for the 50 pictures a had on the SD card.
To me, these file, unless linking to actual photos stored on the SD card, take up extra space in the phone's memory (not worried about the SD card). I wonder if I can safely delete them (just the files...not the folder)?
Basically I want to know how to get a list or array or any type of data about the files that have been stored in an package specific data section. By this I mean that after using something like:
FileOutputStream fOut = c.openFileOutput(fileName, 0); OutputStreamWriter osw = new OutputStreamWriter(fOut);
How can I get a list of the files saved to the data location of my application where this file and other files or saved so that I can choose which file I wish to read or edit. I've searched and searched for this but have not found anything of use any help will be greatly appreciated.
How do you go about checking what is stored on your phones memory and deleting content? For example I used dropbox and downloaded a 7mb photo onto my phone. Can't find it in the photos app or anywhere else. Going into SD & phone storage under settings doesn't do anything. It says I have 70mb available space under phone storage but you can't click on that to get any further info. Same goes for the SD card options.
