Android :: Resource IDs And SharedUserID
Jul 20, 2010
If I am not wrong with the way android:sharedUserId is intended to work, then my question is how to avoid overlapping resource IDs? appt seems to aways start IDs at the same initial value (i.e. drawables at 0x7f020000), so there will be sort of conflict or ambiguation. As for now I failed to get that cleared w/o digging in OS sources. Or I miss anything, like magic "undocumented" appt option (not that aapt is documented at all)?

I have two applications in the field that share the same sharedUserid.What I just found out was that there is a bug in Android, where un- installing one application removes permissions from the other application also - thereby rendering the other application useless. Looks like this bug has been reported before : http://code.google.com/p/android/issues/detail?id=2773 This is a critical bug.Is there a workaround or a tool that can be provided to the user to recover back to a working version. Un-installing and re-installing the the application to start from scratch is not a acceptable option for our users,they stand to lose a lot of valuable data.

For the next version of our application, I want to change the sharedUserId since we now use an internal control dashboard app which must write to the other app's settings files.But since the app is already installed on many phones, will this be a problem? I ran a little test on the emulator, and I'm seeing exceptions in the device logs that *.bak versions of the preference files cannot be written. Not sure how critical that is. Curiously, safing settings still seems to work, even though the shared_prefs folder had been created using another Linux user ID.Did anyone try this before?

I'm looking to update my app and provide a sharedUserId as part of my manifest, so that the several apps I have can all nicely look at each other's private files if necessary. Unfortunately, I've discovered that adding a sharedUserId where it did not exist before will change the userId and make me unable to modify current existing files.Is there a graceful way to handle updating your sharedUserId now that I need its functionality? Or am I pretty much resigned to requiring people to uninstall and reinstall my app to be able to do this?

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 am using the function decodeResource(Resources res, int id, BitmapFactory.Options opt).I am using it in the following way:
BitmapFactory.decodeResource(getResources(), R.drawable.image,opt);
My question is instead of using R.drawable.image which is an image in resdrawable folder, I want to use a image from sdcard.Is it possible? How to get the resource id of an image in the sdcard?

I do have a lot of language specific resources. There's one point in my Android apps where I do get a resource value and need to translate this value into the matching id. The value is not neccessarily in the language specific file for the current language (en/de/...). It's somewhere in there ... and it's unique.
After reading the docs and this thread "http://stackoverflow.com/questions/3476430/get-resource-id-by-passing-name-as-a-parameter-in-android" I thought that "getIdentifier(String name, String defType, String defPackage)" is the correct way to go but I can't get it to work. The result is always "0".
This code is part of an activity and I'm on Android 2.2.
Is it possible that Android doesn't take all resource files into account and searches just in the current language specific one?
For an example
CODE:....
To make things clear. I don't want to mis-use string resources as a database. It's only one part that occurs on very rare situations.

I will admit - I've never had a smart phone. Never. I was going to get one last year, but waited b/c I heard 2010 was 'the year of the smart phone' - and I'm glad I waited.Though I'd have to see it in person to know for sure, but I'm almost positive that DroidX will be my first smartphone. I'm VERY excited, but I want to make sure that I'm educated enough to use it for all it's worth (ie: my mom has had every iphone, but just leared to text message last month).Is there some place/book/thread/site that I can study which would tell me about smartphones from the very most basic all the way to the more advanced? I'm a smart girl, but I have to start somewhere!

My application has resource conflict problem. Did some investigation, seems like all the resources within the apk file are cached after they are loaded on demand. The cache is stored in Resources.java mDrawableCache. The key to retrieve the drawable from this cache is combining the data and assertCookie fields of TypedValue class. In my application, there are 2 resources, ex. a color background and image drawable, evaluated to the SAME key value.. So just wondering, how can it happen?BTW, I am using eclair SDK.

Is it possible that a resource id (such as a generated id for a string resource) can be a negative int?Often, when defining a method that accepts a resource id, I want the caller to be able to specify a "null" value.For primitives this is not possible, but I'm wondering whether "any negative value" may be a good approach? Alternatively I suppose it would be OK to specify the argument as an Integer and take advantage of auto-boxing.Thoughts?

Can this kind of files (buttons) be used to create android applications, or you must use predefined buttons?

I'm sure this is simple, but I've got myself confused over it.I have an image resource, such as R.drawable.myimage, and I want to convert this into a URI.I tried:
Uri selectedImage = Uri.parse("android.resource://com.my.package/" + resourceId);
but this just returns a NullPointer. The resourceId needs to be dynamic (so I can pass any image to it), not just a hardcoded "myImage".Any help please?

I am looking for an efficient way to find out if a resource (mostly a drawable) is used in java or in an XML file.
The problem is, that on my current project the drawables are changed often and now I have some drawables, which might never be used.
Is there a tool/way to find those unused drawables without search each filename in the whole project?

I have an apk (App1) that has a raw resource (res/raw/mytextfile.txt) and I would like to read that text file from another apk (App2). I define a content provider in App1 and I override the openFile(Uri, String) method as follows:
CODE:.......
App2 does the following to try to get access to mytextfile.txt:
CODE:.........
However, when I read and write out the contents of the BufferedReader, I get way more than just the contents of mytextfile.txt.
I played with this some more and found that the file desriptor returned to App2 is pointing to the App1 apk file. I wrote out the contents of the BufferedReader to a file and did a binary comparison to App1.apk. The two files were identical.

I have requirement to implement button in lockscreen. So i have added new image here *frameworksasecore es drawable.* And i have modified the Keyguard_screen_lock.xml. Here i have added the ImageButton view. And i have even modified the strings.xml to display different string. As in the following discussion it has told like this. *You must not add public resources because it would change the public API and thus make your Android phone/device potentially incompatible with other Android devicesYou must not add public resources because it would change the public API and thus make your Android phone/device potentially incompatible with other Android devices.* ** *Please find the previous discussion in the bellow link*

I'm trying to find a way to open resources which name is determined at runtime only. Let me explain in more details. I want to have a XML that references a bunch of other XML files in the application apk. for the purpose of explaining lets say the main XML is main.xml and the other XML are file1.xml file2.xml...fileX.xml...
what i want is to read main.xml, extract the name of the xml I want (fileX.xml) for example. and then read fileX.XML. the problem I face is that what I extract form main.xml is a string and I can't find a way to change that to R.raw.nameOfTheFile

I have some image names stored in a database, but the images themselves are in the /res/drawable folder of the application. I need to assign these images to some views at runtime, and I'm currently doing it this way:
// public static final String DRAWABLES_PATH = ":drawable/";
int resId = getResources().getIdentifier(packageName+DRAWABLES_PATH +imageName,null,null); mButtonX.setBackgroundResource(resId); //
Is there a more efficient way to do it? Or should I be storing the images directly in the database (they are many)?

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.
