Android : Write To A File Saved In Local Folder In Droid?
Oct 27, 2010
I am having a file in the folder res/raw/a.xml.
I want to write some data to this file?
How it can be done in Android?
How can we access a file stored in local directory in order to write data to that file.
can anyone help me in sorting out this issue ?
I am new to Android and relatively new to Java so please bear with me. I have an XML file stored in the res/xml that I am trying to write to. I know how to read it using XmlResourceParser, but I have not been able to find a way to write to that file locally. Could someone point me in the right direction please.
i was trying to write to a text file in the raw folder inside my project, but found out you cant. After that i made it write to the sdcard and that worked. I was wondering how most games keep score data and that stuff.is there a location where data is saved to such as a cache folder.
I just gave up my Blackberry Storm for the Motorola Droid X. I'm seriously considering taking it back. That it keeps message history in your contacts is in and of itself reason enough, but the final straw was when I just tried to save an email only to realize THERE IS NO SAVE FOLDER!If there is an app that will allow me to save an email (right now the only folders are inbox and trash) please let me know, or this crap goes back. By the way, I don't mean save an attachment. I mean save an email. On the storm if you hit save on any type of message it goes to your saved folder. Even if you delete everything in your inbox. To delete it once you've saved it you must delete it from the saved folder.
I am working on some a application where I have to update some files present in assets / raw folder runtime from some http location.Can anyone help me to by sharing how to write files in assets or raw folder programmatically?
My program contains a file with the name "size.text", which contains just a word "15". If a user choose a value from a spinner,say 17, then the chosen value should be stored in the file and replace "15". I have added the permission to the program <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission> But somehow i can not make the chosen value be written to the file. Here is my code...
I've developed an Android App. that takes a picture and save it on gallery. The problem is that I don't know how to write a Bitmap/byte data which I get from taking pic. to the gallery in .jpg/.png format.
the question i have is simple but hard to put in words, ill give it a try anyways.i am trying to load a web page in web view,however the load time is a little high.is there anyway i can put the images in the assets folder and load them from there instead?if not, is there a way i can load the whole site from the assets folder, providing that my php files can still communicate with my internet database?i have already read most tutorials however they are pretty vague when it comes to concrete help.
My SD card on my droid x went bad so the verizon store gave me a new one but it seems they formatted it for a blackberry hence I see blackberry folders in there Can someone tell me the file/folder structure for Android 2.2? Once I format and clean it up, what are the directories I should be creating? If there's a link that describes it, that would even be better..
I'm using an ant build file that has been generated by android. Our Android application requires a JAR file that lives inside the lib folder of our project, so I need to adjust the classpath that ant is using when it builds stuff.
When I run:
ant -lib lib debug
the project builds just fine, but this should really be inside the build file itself. The build file that android generates references the android_rules.xml so a lot of this stuff is automated. I guess my question, what the best practice here when working with the Android build rules ?
I'm trying to read some local files, and ive been reading a lot of stuff about it, but i still don't know where to store the files on my phone and how to get the right path. Some say, it should be stored on /data/data/your.package.here/files but where is that, i mean i can get there when using the emulator but i have no clue how to put files in this on a real device.
All 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?
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.
The side bar in eclipse shows a red cross on the title of my project folder but there are no such signs in the directories below it in hierarchy. In which particular file does error exist? How can I know that
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:
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 would like to know how to write to file. I have tried using OutPutStream out = new FileOutPutStream(fileName); out.write(byte , 0, length);This way always returns Parent directory or File is not writable.I have also used openFileOutPut(fileName, MODE_PRIVATE) method but this method works properly if it is called from the same class which has extended Activity and I am writing to the file in different class and that too in different thread.I have tried to get the Application Context through getApplciationContext and call openFileOutPut method but still theres something wrong that I am doing.So please can someone suggest me a proper way to write to a file.
