Android :: Specify Resources In Android Project To Be Stored On SD?
Oct 19, 2010
I'm writing an application that contains a lot of videos (~ 600 Mb). Obviously, this is too much to store in the device's application space and these videos need to be stored on the device's sdcard. However, I'm trying to decide what is the best way to do this. I could put the videos on a web server and let the user download them as he views them or in the background as he's watching other videos.
But ideally I'd like for the videos to be included in the application download from the market. I'm not even sure if that's possible. One option would be to store the entire application on the sdcard, videos and all, but that would make the application only work on Android 2.2 and higher. Is there a way to specify resources in your Android project that will not be stored in the application space but instead stored on the sdcard?

I have project A with some classes and some resources (used for classes configuration). I'd like to reuse its classes (and resources necessary for them) in another project B (and possibly in more projects). Currently I have 2 projects in Eclipse and they both builds fine, but when project B is started in emulator it fails with error.It should get classes and resources from both projects and package them together. 2) Make a third project which consists of symbolic links to classes and resources of those two projects. 3) Make project A as a service and consume it in project B. They all are imperfect: - 1 and 2 would pack classes and resources of project A into the .apk of project B. - 3 has performance penalty and reuse is not so easy.

I have some images in my drawable folder and they have landscape versions in drawable-land. However I want some of the landscape images to be shared, as it seems a waste to duplicate the file with a different name. Is it possible to make a sym link (shortcut) or something for one of the duplicated files to prevent wasting space
Folder explanation below as I'm not great at explaining myself:
/drawable
> image1.png
> image2.png
/drawable-land
>image1.png <-- This image
>image2.png <-- is identical to this file

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

Somethings I'll have an? .xml file selected when I compile a project, only to have a? .out.xml generated. Deleting the file doesn't clear the error, and Eclipse won't compile the project. It just reports that your project contains errors. The solution is to go to Project/Clean. This will clear the error in the project and allow it to compile.

I can now get our Android project to talk to our non-Android project. But there's still an issue: I are trying to have an Android class call a non Android Hello World class. I tried compiling our non-Android Hello World class in a separate Eclipse workspace. I then packaged it into a jar. I imported that jar into our Android Hello World class.
I then called one of the methods in the non-Android Hello World class. When I ran the Android Hello World class as an Android application, the following runtime error occurred. Here are the Android debug logs:
08-11 09:07:56.764: ERROR/AndroidRuntime(333): FATAL EXCEPTION: main
08-11 09:07:56.764: ERROR/AndroidRuntime(333): java.lang.ExceptionInInitializerError

I followed the instructions here on how to create an Android library project, and use it in an Android application:
http://developer.android.com/guide/developing/eclipse-adt.html
But it is not working. I can see the library project is added to my application but I cannot reference anything in it because it won't build. The R.java file from the lib is NOT being added to my application project, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file.
I don't know if this has anything to do with it, but in the console there are messages stating that the there is "No resource identifier found for attribute 'X' in package 'Lib Package'. My library package has a a few styleable attributes defined for a custom view I made, all of which are being complained about in this console message. The library builds just fine, and I don't get those messages in the console until I hook the library to my application, so I don't know what's up with this.

I have 2 android projects out of which I modified one to work as a library. I want the main project to refer to this library to perform few functions. While this scenario works just as expected, I want to introduce one more functionality. I want to link this library project with another just a java project which has code common to both Android and Blackberry applications. This second part however doesn't seem to work and throws "The application <appname> (<package name>) has stopped unexpectedly. Please try again" with a ForceClose button. I would greatly appreciate if someone can give a brief information on how to make this work.

I am a C# developer and getting started with Android. I am attempting to duplicate a couple applications I already have in VS. The project is made of 2 executables and 1 common assembly. The 2 executables contain the application specific logic while the common contains centralized forms and logic (such as login form). I am using Eclipse. So how can I accomplish this layout?

When I right click the project in the eclipse, select "Properties". In the property page, select Android. According to the document, you can add the library project through that page. But my problem is that, there is no library information on the page. It only lists "project build target"

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...

I currently have a few classes that are called by an activity (some statically) in which I want to use a string resource. I tried: Resources.getSystem().getString(R.string.mystring), but am getting an error. It seems as though you can only use this within an activity.
Is there anyway to use a project resource in a standard (non Activity) class without having to pass the resource object from the activity calling the class?

I have an app with 2 Activities and an IntentService all which need to access the same SQLite Database table. What's an appropriate pattern to use?
Should I create a ContentProvider that manages access to the database, ie opening/closing, querying, updating etc. And have the 3 clients all access the DB via the ContentProvider?
Or is it OK for each client to access the DB directly? This is the approach I have now and it seems to be working, but I need to close my cursor and the DB after executing every statement or I start generating stacktraces in the log about unclosed DB resources. But closing the DB after each statement seems wasteful and I suspect that this approach will always be susceptible to the stacktraces because there is always the potential for collisions between either of the Activities and the IntentService.
I haven't been able to find any good resources that show DB usage in full. It always snippets that miss out the *obvious* piece such as when should the resources be closed etc.

I'd like to use the RandomAccessFile class to access a file that ships with my application. However, that class only accepts a String which is the path to the file. If I place my file somewhere like the assets directory, how do I construct a path to that file? I know I can use the getAssets methods to read up resources, but those only return InputStreams which cannot be seeked.

I'm developing an Android app for which we will be selling separate content in the Android Market. Since Android lacks an in-app purchasing model as iOS has, I have come to understand that this is the ideal way of selling additional content (but NOT functionality) for Android apps.
So the question is, how do I actually load raw resources from other Android apps, assuming that I know the exact name of the resource, app ID, etc.?

Need some advice from you experts out there. I've just started with Android programming and while I finally got what I want my "Hello World" to do, I feel as if I'm bludgening my way through rather than grasping concepts. I created three EditText boxes. Below those I created three Spinners. Pick a number in the Spinner and it will show up in the corresponding EditText box. Spinner 1 correlates to EditText 1, Spinner 2 to EditText 2 and Spinner 3 to EditText 3. I had a hell of a time getting this to work. I do have some cleaning up to do. Is there a better way to pass or reference resources around various classes?

I have a long series of graphics -- icon1_0.png, icon1_1.png, icon1_2.png..., icon12_0.png, icon12_1.png, icon12_2.png -- and I'd like to package them with my android application. Ideally I think I should be able to load them as resources but the resource id's are set up as java identifiers. Of course, java identifiers can't be assembled at runtime. I have to ask for R.drawable.icon12_00 so I cannot set up a loop
for(int icon=0;icon<12;icon++)
for(int frame=0;frame<3;frame++)
//syntax error obviously
BitmapFactory.decodeResource(getResources(), R.drawable."icon" + icon + "_" + frame + ".png");
So is there any way to get resources by their names? Better yet, is there a canonical way outside the resource system to pack data files into an android application package so that I can get at them? I'm thinking about reflection but that doesn't seem like the right solution to me.

I need to add a res/drawable-nodpi folder to my Eclipse ADT project. My project originally contained drawable, drawable-hdpi, drawable- ldpi, layout, etc subfolders, but no drawable-nodpi. How do I add this to the automatic resource build process? I tried to manually create the subfolder and copy files to it, but those resources are not being auto-generated. How do I make Eclipse utilize the new resources subfolder?

I was able to play around with the resource on a different apk and get them using createPackageContext as you suggested.
Here is an example of the code:
CODE:............
This works well. now i am trying to get ALL the drawables (or all the layouts) in this package. i tried a multitude of ways including reflection and AssetManager but was unsuccessful. any tips here? just to be clear i can not use R.drawable.icon as this is a different context.

I understand that the system may kill the activity without calling onDestroy(). Say I have a MediaPlayer that runs even when it's not visible, I would be releasing the player in onDestroy() method.Now, if the system decides to kill the activity after calling onPause() and never called onDestroy(), what does it mean for my MediaPlayer? Is it ever released? This is bigger problem for Camera since I think it requires to be released for other activities to use it.

I have created a subclass of Activity, 'CustomActivity', that overrides the onCreateOptionsMenu and onOptionsItemSelected methods. In a couple of other applications I have extended this subclass to provider a common menu for each activity. Is it still possible to access the resources from this Subclass? By default it uses the resources from the current activity (Strings, xml layout etc.).
