In my application I use SoftReference to cache images, it is working fine with active internet connection. And now I need to cache images, so I could use it in offline mode. What is the best way to implement it? Use complex solution with SoftReference and database? or maybe SoftReference and local storage (sdcard)?

Ever since Google started allowing offline maps (both in the old Google Maps incarnation, and in the current one), I have found that when I download a map section for offline viewing, often there are many details missing (small street names, for example).
Any way to make Google maps download map tiles to their maximum level of detail (the level you could get if you zoomed in all the way), including all street names? You'd think this would be a given, but it seems not to be.
Searching around for discussions of this, most articles and forum threads are just about tile caching in general, not level of detailed cached.
How to cache images after they are downloaded from web
View 5 Replies View Relatedi have an application which loads urls from a website. Now i want that the aplication uses the cache when offline. But i just get the failure site which says that im not connected to the website. At first i set the Cachmode to Load_Normal but this doesnt help. Next i tried a realy "silly" approach using the ConnectivityManager:
cm = (ConnectivityManager) this.getSystemService(Activity.CONNECTIVITY_SERVICE);
if(cm.getActiveNetworkInfo().isConnected()){
mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
mfnWebView.loadUrl(url);
}
else{
mfnWebView.getSettings().setCacheMod e(WebSettings.LOAD_CACHE_ELSE_NETWORK);
mfnWebView.loadUrl(url);
}
but this just leads to crashing the application. Is there a simple way to load the cache when offline and existing. And just if not existing showing the failure message.
I am new in this forum and use the android at the first time.
I just want to ask some question, what GPS application which is good and applicable for search map and offline mode when operate.
I think my evo is starting to lose itself. It's been doing some weird stuff lately. Not showing icons/images on website unless I deleted the cache/history/restart the phone. I also lost pinch to zoom until I restarted the phone. It has done the icon thing twice. A couple of minutes ago, it restarted itself. I'm concerned but so far it's not enough to justify a trip to the store. I would return it and get another one but the store would charge me $35.

View 2 Replies View RelatedAny app for GPS navigation which has voice routing possible in pedestrian mode? I sometimes need to go to some destination in a part of the city which is not familiar for me.
However, the navigations I tried, have voice routing only in car mode, so it has to take in account things like driving directions etc. which the pedestrian does not have to respect and thus the track is much shorter.
It would be nice if I, for example, just could get off the bus, switch my GPS on, select destination, activate the voice routing and put my phone in a pocket and let the navigation voice guide me to the target place. It would be more comfortable as I sometimes see the map very poorly and also have to keep an eye on other pedestrians, cars etc.
Currently tried Sygic and it does not have this.
i 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
Quote:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="h**p://schemas.android.com/apk/res/android"
package="com.example.lyold"

Any way to open local KML files with google maps in offline mode ? I want to open kml ONLY in google maps, i know there are several apps out there that support kml files....
Seems fairly straight forward Settings > Apps > Uninstall. But is there any reason, or a good idea to boot into recovery mode and wipe cache?

I was rooted and decided to unroot for giggles. After i did I went to root again and now I am getting this: "E: cant open/cache/recovery,command " When I reboot into recovery mode.

View 1 Replies View RelatedI'm implementing an image cache system for caching downloaded image.
My strategy is based upon two-level cache:
Memory-level and disk-level.
My class is very similar to the class used in the droidfu project
My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.
Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.
Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:
CODE:.................
This method is called sometime afte a disk writing:
CODE:..............
What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:
CODE:.....................
My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"
I'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?
I'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.
Just curious how many have this issue.If you are unsure select the link below and find out pls.

View 1 Replies View RelatedWhen I bought my Nexus One, I took the card out of my G1 and put it in my N1. I've developed an app and I know how it works on the Nexus but I want to test it on my G1. I wanted to see how my app looks on a G1 so I connected it to my computer and put my .apk file into the downloads folder on my G1's SD- Card. Ok, now my app is on my OFFLINE G1 but how do I install it? Can I install it with only the native apps on my G1? Right now, I don't see anyway to view the file. I know I can take the chip out of my N1 and put it back into my G1 and then simply download and install it but I would rather not do that.

View 6 Replies View RelatedI am developing an application with TripIt integration and I make a call to their API and I get all my data in JSON format and save it in an object ListTripResponse. This object contains all the data I need over all the application. What I do now, I write this object to a text file (i serialize my object and save it as a file with ObjectOutputStream) and in every activity I read this file. But this file is pretty long and it takes a while to read it. And i have to use and read this object in every activity! Isn't there a better way to do this? I cannot save this file in a database because the structure is to complex.
View 3 Replies View RelatedI'm somewhat unfamiliar with the droid incredible's GPS features. I know it uses A-GPS, but I've been led to believe that the use of cell towers is only to facilitate the acquisition of the almanac or when GPS signal is unavaible altogether. I'd like to use my phone's GPS while camping, at which point I'll be well away from cell coverage. Will I still be able to get a GPS signal. If so can anyone reccomend a topographic mapping software that I can download maps from to my phone?

I have a new HTC Hero and TELUS imported the contacts from my old (OLD) Motorola i570 dumbphone. I need to do a lot of cleanup of the data, including specifying proper first/last names, merging postal and e-mail address data from my Palm TX's database, etc. I used "Contacts Manager" to export my phone-based contacts to an XML file on the SD card. It can apparently import an XML file as well, but I can't get it to work. It always complains about importing a directory instead of a file.

View 1 Replies View RelatedI don't currently have a data plan. Since I'm on WiFi 95% of the time, I don't plan on getting one. The only thing I haven't been able to do easily (without a data plan) is use Google Maps while driving/walking.If I load the maps before leaving a WiFi hotspot, my location is tracked and I can pan around the map. Of course, as soon as I want to view another uncached portion of the map, I can't.Maps are small, and it would be perfect if I could cache maps for a certain area - say everything within 100 mi of my house. Any ideas?
