Android :: Share Classes Between Different Android Projects?

Jan 20, 2009

I have two projects that share classes in a third project. Eclipse happily allows me to reference these external classes when I am developing the two dependant projects (as long as the Java Build Path is set up right), but when I try launching the dependant projects, the external classfiles are not copied into the .apk for some reason, so at runtime I get unsatisfied link errors. I don't want to have to maintain multiple copies of the same source file, or even have a copy of these external classfiles in the dependant projects. I also want to avoid adding an extra build step where I build the external classfiles, package them up in a .jar file and include them in the dependant projects. How can I get the Android SDK to simply put a copy of any referenced (non-SDK, non-project) external classes in the .apk at build time?

Android :: Android - How To Share Code Between Projects Signed With Same Certificate

Apr 27, 2010

In Android documentation concerning code signing we can read: "By signing multiple applications with the same certificate and using signature-based permissions checks, your applications can share code and data in a secure manner." How exactly such code sharing can be done? Is it possible to release main application and multiple exchangeable plugins then discover them at runtime? What does source code looks like and what are advantages over "standard" intents calls from/to different APK packages?

Android :: Can't Use Dependent Projects In 1.5 / Fix This?

May 5, 2009

I have 2 projects in the following layout

MainActivityProject -> BaseProject

(i.e. MainActivityProject depends on the other project). Both are android projects created with the eclipse "New Android project functionality) however, the BaseProject does not have an activity defined. However, in BaseProject I define an activity base class where MainActivityProject's Activity derives from. This used to work fine up until 1.1 but now with the 1.5 SDK I get ClassNotFoundExceptions when launching the app.

Any suggestion on how to fix this? I obviously dont want to copy all the sources to a single project as I intend to reuse my Activity base class for other things (it contains some boiler plate stuff that I dont want to have in each and every activity.

Android :: Projects In Two Different Locations And Importing In Eclipse?

Mar 10, 2010

I always face this problem in my eclipse. I would like have a copy of the apps in all the versions of SDKs/NDKs. And once I have a project in eclipse, and if I have to import the same project from a new location, I get the message saying "Can't import, project of the same name already exists". Is this how it is? We cant import the same project from its 2nd location in eclipse? Everytime I delete the project from old location and put it in new. I know, it is a very unacceptable approach).

Android :: AIDL In Multiple Projects In Eclipse

Mar 16, 2010

I have problems with the following: I want to create to applications. One with a Android service and one with a Activity that will use functions on the Service. Before I splitted this in to applications I got everything working in one application. I can call functions (that are definned in the aidl - file) on the service without problems.

Now the problems coms. I splitted the application into two parts, a Service application and Gui application. The bindins to the service (in the gui application) works and I see that the service is getting created. Then in the onServiceConnected function of the ServiceConnection class I created the following:

mService = IMyService.Stub.asInterface(service);
And this gives me the following exception:
03-16 13:53:05.549: ERROR/AndroidRuntime(881): java.lang.NoClassDefFoundError: MyPackage.IMyService$Stub

It looks like he can't find the Stub class in IMyService. But the Stub is part of the java file generated out of the aidl-file. Why I get this exception or how I can resolve this?

Android :: Eclipse Not Importing Jar Dependencies Between Two Projects

Jun 7, 2010

Here is the situation.
I have a java project "LicenseGenerator" in eclipse that depends on commons-codec. I have therefore added the commons-codec jar file to the build path. I have Junit tests and everything is working fine. I have made a different project in the same workspace - which happens to be an Android project - that needs to use my LicenseGenerator classes. I added LicenseGenerator to the "projects" tab in the build path - the classes were recognized and I was able to use them.

Everything compiled and ran. However, when the part of the LicenseGenerator that used the commons-codec was called from my Android project I got the following error.
Could not find method
org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString,
Referenced from method
This basically tells me that the commons-codec was not packaged which the Android project, so I added the commons-codec to the android project as well but the same error appears.

Android :: Including Other Eclipse Projects In Application

Jan 12, 2010

I have a library-only Android eclipse project (no main class, only library classes) that I want to include in my main Android Application project. I went to the Build Path and added the library project to the "Required projects on the build path" on the Projects tab, and checked it on the "Order and Export" tab. However, when the application is run, it emits VerifyError exception, because the class from the library project didn't happen to be packaged together in the apk.

Android :: Unable To Import Example Projects From Book

Jun 17, 2010

I am trying to import projects from a book "Beginning Android 2" but when I choose the root directory the "Finish" button is still grayed out. I've tried importing the project from scratch with no success, and I've also tried to create a template project with the same name and everything and then importing into that (Import existing projects into workspace) but it always says "No projects are found to import".

The contents of the folder are: Res folder, src folder with .java file, the manifest, build, and default.properties files.

Android :: Way To Restore Old Behavior On Other Projects In Build Path?

Apr 28, 2009

We have an application cut into 3 android projects: * Project REAL (the real android project) * Project LIB1 (an android project without any activity, just to make android reusable classes) * Project LIB2 (same as LIB1) LIB1 and LIB2 are android projects rather than J2SE ones because LIB1 and LIB2 use Android classes. Project REAL has LIB1 and LIB2 in its project build path in Eclipse. In SDK 1.0 and 1.1, no problem at all when running the project REAL from Eclipse, it mixes the code of the 3 projects and produces one big APK with everything in it. But now in SDK 1.5, it installs 3 different APKs on the emulator or on the phone (I tested both), and the project REAL immediately crashes because of a Verify Error: it does not find a class that is in LIB1. The size of the produced APK is smaller, indeed LIB1 and LIB2 classes are not in it... I tried using uses-library in the manifest like google maps library but it complains at installing, we have a "missing shared library" error. I tried adding class folders in build path, it compiles in Eclipse but we still have a Verify Error. Same thing if we use external class folders in build path. The only thing that worked for me was to add an eclipse folder, which is in fact a symbolic link, and to make it a source folder. But that solution is not convenient for us because when we share the projects in SVN, the referenced paths are different for each developer. Using eclipse path variables can do the trick but it is far from being convenient. Indeed, if we have to reinstall Eclipse or if we move the place we check out the code in our developer station we have to reconfigure all these messy path variables in Eclipse. Is there a way to restore the old behavior on other android projects in build path ?

Android :: Speed Up Builds On Large Projects - Renaming PNG

Sep 16, 2010

I ran into a problem of slow builds and thought I'd share the solution. I'm porting an iPhone app to Android, and as soon as I added the images to the project (400+ pngs), build time went from about 5 seconds to about 40 seconds. This is on a new machine, quad core i7, 8GB ram. The resource processor (aapt) was to blame. Every time I made a change to a layout xml file and hit save - bam, wait 40 seconds. After running aapt in verbose mode, it was obvious what was happening - aapt does png optimization every single time. Optimization is slow, and aapt only used one core. So it makes sense to turn this optimization off. Just run optipng once, no need to optimize every build or every time I save a layout xml file.

So how do you turn png optimization off? You can't. There is no Eclipse setting, no command line option for aapt. Digging around the aapt source, I noticed something funny though - it only optimizes images in the "drawable" folders that end in ".png". http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;...
Solution: rename all the pngs to end in uppercase ".PNG". Then aapt simply copies the files without optimizing. My build time is back to 5 seconds!
(Caveat: this won't work for nine-patch files - they still need to end in lowercase ".9.png".)

Android :: Reusing Java Source In Multiple Projects

Nov 24, 2009

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?

Android :: How To Import Individual Projects From Source Code?

As far as I understand, all the built-in standard apps like (email, music, calendar etc) are built using the same API.

I'v been trying that but I am getting compilation problems like class resolve failure. Am I doing it wrong? What do I have to do to import a project in eclipse without compilation error. I am interested in the Music application.I have setup the latest android eclipse plugin and run test applications with it, so my setup is OK.

Android :: Improve Eclipse Performance For Projects With Lots Of Resources

Sep 13, 2009

I have notices following:

If I have a project with minimum files in res folder, the project saves quickly, compiles quickly and launches quickly. But if I have a lot of resources, my project is saving, compiling and launching during relatively long period of time. This is really frustrating if you do some minor UI updates, and you have always wait Eclipse to generate R file etc.

Any suggestions?

Android :: String Resource ID Values Guaranteed To Be Consistent Over Different Projects

Jun 7, 2010

I have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English.

So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?
