Android :: Reusing Code And Resources From Another Project
Dec 10, 2009
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.

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 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

How can I reuse code AND resources in several applications? I have a fairly large code base (including resources) that I want to reuse i several applications. How can I do that?
I did try to use the Android Library concept (http://developer.android.com/guide/developing/eclipse-adt.html#libraryProject) but never got it to work in Android 1.x
I'm amazed by the lack of information on the subject. It seems like Google has aimed Android development at pet projects and not real development. Variant handling should have been solved ages ago.

Reading values like integers, strings, colors, etc. from resources (xml files) is easy and well defined at http://developer.android.com/guide/topics/resources/available-resourc.... But what about a float value, like 0.1 or 1.4? How can such float value be defined in resource file and accessed from code? Is it possible at all?

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've been working on my project for a while and have decided to share it's source so that I can get help from people and finish it and post it to the market (it's a highly addictive and fun card game). However, I have published it on google code at:
http://code.google.com/p/bestcardgameever-android/
And when I tried to download it with a friend that can help I kept getting messages saying that it is not an android project from eclipse I'd appreciate it if somebody could tell me exactly what needs to be uploaded and what doesn't need and how can I make it work - if you have done it before - you probably can easily help Thanks! also, if you can and want to generally join the project as a developer graphics person or web designer.

The following code was copied from one project to another. No errors in project one.
In project 2 I get:

-implements androd.view.View.OnClickListener.onClick

I want to be able to have two projects, one that contains production code and one that contains test code. This shouldn't necessarily be an Android-specific question, but I'm want to write some unit tests for some non-platform-specific Android code on the host PC.
I created a new Java project so I can run the unit tests on the PC and only include the non-platform-specific classes from the Android project. Both projects are opened in the same Eclipse workspace. I assume I need to somehow include these Android-project sources explicitly in the new project where I'll run the Junit tests, but I can't figure out how to do this.

I am currently moving from Xcode and iPhone development to Android with Eclipse. I want to have a shared code project so that I can store all the code to be shared across apps in one common library. However it would appear that the only android project available is for applications and not for code libs how can i achieve this?

I'm pretty new to android, and just finished setup my environment and reading some tutorials. Then I got sdk samples from the web. Okay, what I wanna ask you is that is there a way to start a sample as a project in the Eclipse? I mean like clicking a project file in c# or a solution file.code...
Or, do I need to make a new android project and import (or add files? maybe) them?

I have an Android code base which uses APIs with settings to get different data for several apps. All apps use the same code base but with one or two design tweaks. So how do I re-use the main code base without having to copy the whole Android project each time?
iPhone uses multiple targets in the same project which works well. If android cant do this do I need to compile binaries of the code base in one project and then import into each new app project? If so how? I'm using Eclipse and am an intermediate Java developer.

In my app, user starts a service and shows a notification from activity A. The notification creates a Pending Intent that will invoke activity A should the user tap on it. The problem with this behavior is that, if the user starts the service (which shows the notification), drags down the notification bar, then taps the notification, I now have two activity A's in the display stack, one on top of the other and both exactly the same. How can I re-use the original activity A in this situation so the user isn't duplicating activities?

I'm currently developing for Android using Eclipse. I have a lexicon viewer application (with package name "com.mycompany.myviewer") that I want to reuse multiple times, just changing specific resources such as app name and icons.For example, I have a certain publisher "Publisher1", who publishes the lexicons "Lexicon1" and "Lexicon2". I would need to two applications: App1 with certain name and icon, and App2 with another name and icon.What is the best way of doing this in Java? In visual Studio (and C++) I could create two projects based on the lexikon viewer app and use conditional resources to get the right name and icon. Is there some way of doing something similar in Java?

I'm writing a widget. Currently, I'm have a simple ImageView, and calling RemoteViews.setImageViewBitmap(). I'm using a service to do the updates.
I thought it might be a good idea to reuse an existing RemoteViews instance, so I'm only querying it the first time around, and subsequently simply call setImageViewBitmap() with the new image.
This works well initially, but after some time I first start getting "!!! FAILED BINDER TRANSACTION !!!" errors, and later, an OutOfMemory exception.
Simply creating a new RemoveViews instance every time works flawlessy on the other hand. I'm just curios why that would be, any ideas?

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

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?

All the examples I've found online for displaying a gallery of images require creating a custom Adapter and doing a ton of manual work. Is there not an Intent that I can simply pass a path or filter to in order to reuse the default image gallery functionality (display thumbnails, touch to view full pic, sharing options, etc) but limit the results to my application's storage directory?

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.
