Android :: How To Save Files?
Mar 12, 2010Do you know how to save files?

Do you know how to save files?
"Every Android-compatible device supports a shared "external storage" that you can use to save files. This can be a removable storage media (such as an SD card) or an internal (non-removable) storage. Files saved to the external storage are world-readable and can be modified by the user when they enable USB mass storage to transfer files on a computer." PROBLEM: I cannot write to a file on the sdcard. QUESTION: Is it possible to write to a file on the sdcard?
If YES, what do I need to do to make File.canWrite = true? I am using Android 2.1 update 1, API level 7, Eclipse, and HVGA skin. I am running my app / troubleshooting on the Android SDK ADV. When the AVD is running, I check settings > sdcard total 49.21MB, available 49.07MB................
I'm saving files in
sdcard/Android/data/<packagename>/files
the problem is that everytime i download the app to the phone - the folder and it's contents get deleted.
anyway to prevent that.
ideally i would want that to happen only when the user uninstalls.
for debugging and user app upgrades - i'd like the folder and it's contents to remain.
I need to save my Android phone files on my Mac before I factory reset my Evo V 4G WiMax.

If no network connection is available it should be taken out of the assets directory. I know I can reference fils in here using the file:///android_asset/ base URL, but can I write to it, too?

View 7 Replies View RelatedI have a Motorola Moto G 8GB which is running very low on storage (only about 800mb left). This phone does not take Micro SD cards but it comes with 50GB Google Drive storage. However i haven't used this at all. I am wondering whether i could download android apps and games to google drive, dropbox etc. Games like Real Racing take up about 1GB so i cannot download it to my phone. Can i download it to the Cloud? If this is not possible, is there any way that i could save the app data on the cloud. E.g. The Simpsons: Tapped Out is about 37mb to download off the play store, but then you must download the updates etc which are about another 250mb. is there anyway to save this 250mb on the cloud. Or any other games data.

If the phone contains SD card, it is clear that files should be saved there, but if there is no any external storage. where would you recommend to save to?
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).

The following code works great:
CODE:................
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.

View 1 Replies View RelatedFrom the Android documentation:
"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.
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?
View 3 Replies View RelatedI 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 cant send any files(pictures,mp3 files) through bluetooth.
Can anyone give some solution on how it works?
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)?

View 1 Replies View RelatedHow 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.
View 1 Replies View Relatedgot a Samsung Galaxy S4 (for several years I had iPhones) and I am enjoying it. Now that I have gotten all my music files away from iTunes' clunky clutches I have reorganized them and they are on my S4's sim card and it works great.
The issue is that I have updated a few of the files and moved a couple more around. I want to update those music files on my S4 from my PC. I could just delete the Music folder on the S4 and recopy everything over, but that seems to be a huge overkill.
What is a good way to compare files between my S4 and folders on the PC and match/update between the two? I am using Windows 7. I have tried to map the Sim Card as a drive but couldn't get that to work. I have Kies from Samsung but that is kinda clunky. I have also tried AirDroid (which I think is great) but I can't really sync files with that. Normally I would use a Windows application like Beyond Compare or WinMerge to do something like this.
