Android :: Reading Resource Files From My Own APK In Android Native Environment
Apr 16, 2010
I'm porting to Android. My existing project has a ton of resource files that I'm porting into my Android project. I have them all in /res/raw/, and I would like to access those resources in my native library with functions such as fopen() and such. Can this be done, or do I have to go through JNI for this as well? I would really prefer not to, for ease of porting and possible speed and memory reasons.

I'm running into a strange problem while reading from an InputStream on the Android platform. I'm not sure if this is an Android specific issue, or something I'm doing wrong in general.
The only thing that is Android specific is this call:
CODE:........
This returns an InputStream for a file from the Android assets. Anyways, here's where I run into the issue:
CODE:........
When the read() executes it throws an IOException. The weird thing is that if I do two sequential single byte reads (or any number of single byte reads), there is no exception. Ie, this works:
CODE:........
Any idea why two sequential single byte reads work but one call to read both at once throws an exception? The InputStream seems fine... is.available() returns over a million bytes (as it should).
Stack trace shows these lines just before the InputStream.read():
CODE:........
Changing the buffer size to a single byte still throws the error. It looks like the exception is only raised when reading into a byte array.

Anyone knows of an RSS reader with nice UI, offline reading, and native (built-in) reading capabilities?
I tried feedR and NewsRob, but they both still need to jump to 'browsers' when I wanted to read full articles. This would mean their offline reading features would be useless to me. When commuting, I always had no signals, and it would be useless if I could only read short article because of no network receptions.

1. Compose a new message in GMail. (If you are still without a GMail account, request a GMail Invitation code)
2. Attach any PDF or Word document that you want to convert to HTML You can attach multiple files in this step by clicking Attach another File.
3. Enter your own email address in the To: box and click send.
4. You instantly receive a message in your GMail Inbox folder. Open the message and automatically it will view your PDF attachment as HTML.
5. The contents of your attachment appear as HTML in a new browser window without having to download the file. When you're finished reading the attached file, close the new browser window to return to Gmail.

Is it possible to read the database files in Android 2.1 ? For example, files in /data/data/com.android.providers.contacts/databases/ contacts2.db. If yes, how? And is it possible to replace this file programmatically in order to import / export contacts or any other database 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 have HTC Desire, and I know that I have QuickOffice. The problem is when I put a word or excel file on the .quickoffice folder on my phone, nothing comes up on the mobile when I disconnect. Therefore I was wondering if anyone could recommend me a program where I can either write, or read written files like Word and excel files?

Does android resource files for values and layouts have any way to import other xml files. This is a good approach for products, where there is a core module and many sub modules. The Submodule may also use some of the core defined key value pairs etc. Also, in case with a module, if the view is very complex.. better to manage them as different xml's. Are there any other approach to handle this.. by way R inheritance etc.. I suppose only one R supported per application.

I'm writing an Android application. One problem is your app cannot contain a file whose uncompressed size is bigger than about 1Mb. I have a serialized object that I want to load that totals about 2Mb. My plan was to split this file into two smaller files, then load the object by combining both files at runtime.
However, I cannot work out how to use e.g. InputStream and ObjectInputStream to specify that I want to read the data from two input streams. How can I do this?
For example, say my object was split between file O1 and O2. How can I say "Load the object by reading the data from O1 then from O2"?

Is there a way to access a raw resource file by having its filename in a String? According Google's documentation, I need to use "Resources.openRawResource (R.raw.myDataFile)". This requires that I have the file name at compile time, but what if I have 20 or so files and want to do something to a specific file by passing its file name at runtime?

I've recently upgraded the Android SDK to the latest version, and I'm trying to re-build the ApiDemos project. I've imported it properly.
The problem is
1. the .aidl files aren't being processed at all by Eclipse during the pre-processing stage.
2. R.java isn't re-generated at all by eclipse
Using Eclipse, Helios release.

My application will have some customisation for each company that uses it. Up until now, I have been loading images and strings from resource files. The idea is that the default resources will be distributed with the application and company specific resources will be loaded from our server after they click on a link from an email to launch the initialisation intent. Does anyone know how to replace resource files? I would really like to keep using resource files to avoid rewriting a lot of code/XML. I would distribute the application from our own server, rather than through the app store, so that we could have one version per company, but unfortunately this will give quite nasty security warnings that would concern our customers.

Can I have sub-folders to hold my drawable resources. For example can I store an image in, say, 'res/drawable/content/images/myimage.jpg' and then find that resource via a call to:
id = context.getResources().getIdentifier("com.mycompany.myprog:drawable/ content/images/myimage", null, null);
I have tried this and it doesn't seem to be working (but I may have something wrong). Is it supposed to work or do all the resources need to be in the root drawable folder? Also, are jpeg files supported and drawable resources?

could not run any raw aac files (e.g xxx.aac) in native music player although OPENCORE has a raw aac parser ...
Aacfileparser.cpp (externalopencorefileformats
awaacparsersrc)
This looks like not integrated with Android framework layer through JNI. So music app does not have any knowledge of this file type ..

Installed on Eris (2.1): Laputa, Aldiko, Tulip, Wordplayer
On laptop: Mobipocket, Caliber, MSWord
There's a vast amount of material in MSWord format that I wish to read on my Eris. I can save a file as .txt and put it on my SD card using Astro, etc., but Quickoffice and Tulip are the only readers able to read those files - and both are otherwise inadequate. I've never passed the Caliber IQ test. It seems to convert to epub, but none of those readers ever see the result.

My music has ID3 version 2.3 tags (most common). About 10% (2,500) of my music is AAC (.m4a) format which is MP4 tagged. All my songs are very organized into 11 different genres. Everything has a title, artist, and album assigned to it and looks great in my iPhone, iTunes, MediaMonkey, and Mp3tag program. When I add my music to my Samsung Fascinate, it reads the tags of my .m4a music but when I go to genre, things are messy. It appears to be putting albums in the genre section (only with .m4a files). Example: Lets say I have an .m4a of Garth Brooks, Thunder Rolls, No Fences (album), Country (genre)In my Samsung Fascinate player, it will be found in the genre section under "No Fences". If I click "Country" genre where it should be, the song will not be listed there. It seems to be reading .m4a Album tags as genre and not reading the appropriate tag "Country".I hope someone can help straighten this out without having either manually edit each song tag OR convert all of them to .mp3 and deplete the song quality.

I am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?

I'd like to use python scripts as plugins for an app I'm developing. This seems to be possible by interacting with android-scripting-environment (ASE), as is done by Locale, but I haven't found any documentation about this. How you execute ASE scripts from your own app?

I was just wondering if there was an Android environment that would let you run Android OS inside/alongside Windows, like Virtual PC basically, and let you have full connectivity just like if you were using your phone. I'm not sure what the utility could be right now but it sounds interesting to me.
