Android :: Find Out If Resource Is Used

Sep 21, 2010

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?

Android :: Android Tools And Methods Work Best To Find Memory - Resource Leaks

Jul 18, 2009

I've got an Android app developed, and I'm at the point of a phone app development where everything seems to be working well and you want to declare victory and ship, but you know there just have to be some memory and resource leaks in there; and there's only 16mb of heap on the Android and its apparently surprisingly easy to leak in an Android app.

I've been looking around and so far have only been able to dig up info on 'hprof' and 'traceview' and neither gets a lot of favorable reviews.

What tools or methods have you come across or developed and care to share maybe in an OS project?

Android :: How To Use Resource Within A Custom Xml Resource File?

Aug 3, 2010

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?

Android :: Resource ID

Sep 6, 2010

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?

Android :: Get Resource ID From Value

Oct 11, 2010

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.

Android :: Resource For Very New Beginner?

Jul 25, 2010

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!

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)?

Android :: Resource In Conflict

Sep 4, 2010

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.

Android :: Negative Resource Id Value

Sep 15, 2010

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?

Android :: Creating URI From Resource ID

Oct 3, 2010

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?

Android :: Share Raw Resource Between Apk's

Nov 17, 2010

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.

Android :: More Efficient Way To Get Resource ID Of Drawable From Name

Aug 21, 2009

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)?

Android :: IOException While Reading A Raw Resource

Aug 13, 2009

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.
