Android :: Referencing Projects Under Java Build Path In Eclipse

Jul 27, 2009

I'm working on two projects. One is essentially a library, and the other is an application using that library. Now from the application project, I want to use the library's classes, so I added that project to the "required projects" under java build path. It seems to compile fine, but at runtime, I get this error:

07-27 11:26:57.037: ERROR/dalvikvm(741): Could not find class 'interdroid.contextframework.ContextManager', referenced from method com.bartvanwissen.contextframeworktest.MainActivity.onCreate

Apparently, the library project's classes are not added to the apk file. How can I make sure they are included? Since I'm working on both projects at the same time, I would like to prevent having to create a jar file every time I want to test something.

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 :: Eclipse 3.5 And ADT - Build Path Errors

Jul 9, 2010

I am using Eclipse 3.5 for Jave EE Developers. Plugins installed include: Android Development Tools, Adobe Flash Builder 4, PDT, PyDev. I have problem with running the application I built. I can start a new project, add a button, and run it on an AVD. Then I add another button, try to run it on AVD, and Eclipse says 1) gen folder is missing, 2) there are errors with build path.

I can get ride of the first error by simply refreshing the project in the left pane, but the second error always sticks around. I searched online and on StackOverflow here and here, although several people have the same problem, there is no definite solution I can find.

Android :: Build Error Build/core/java.mk:20 On 2.2

Jun 24, 2010

I downloaded the Android 2.2 source code and try to build it. When I executed the make command, I got an error here like this build/core/java.mk:20: *** frameworks/ex/common: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. Then I changed the frameworks/ex/common/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7. Next place, build/core/java.mk:20: *** external/jsr305: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/jsr305/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7

Last one, build/core/java.mk:20: *** external/guava: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/guava/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
By these changes the code started the compilation.

1. Why the error occured?
2. Changes which I did is correct or not?

Android :: Adding One Project To Another Build Path?

Jul 4, 2010

I'm developing an application that is supposed to run on both Android as well as regular Java SE. I have an eclipse project called foobar-core which contains code that is used both by the Android and the SE version. I have another project called foobar-android, which contains all android-specific code. I need to reference some of the foobar-core code in the foobar-android project, so I added foobar-core to foobar-android in Settings -> Java Build path -> Projects -> Required projects on the build path. This works fine, as I can use code from foobare-core in foobar-android now.

Here's the problem: Both foobar-core and foobar-android are independent git repositories, which means they both have a .git subdirectory. Now I get a lot of warnings on the "Console" tab whenever I compile foobar-android. They look like this:
/foobar-core/src/.git/HEAD conflicts with another file already put at .git/HEAD
/foobar-core/src/.git/config conflicts with another file already put at .git/config
/foobar-core/src/.git/description conflicts with another file already put at > .git/description
/foobar-core/src/.git/hooks/applypatch-msg.sample conflicts with another file already > put at .git/hooks/applypatch-msg.sample

How can I tell Eclipse to ignore the .git files when importing sources from the foobar-core project?

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 :: 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 :: Project Cannot Built Until Build Path Errors Are Resolved

Oct 10, 2009

I'm having "The project cannot be built until build path errors are resolved" after each Project->clean in eclipse. I have two projects with one referencing another. The error appears in the project referencing the another one. When the error appears I go to the 'configure build path' and then remove and re-add the referenced project and then magically the build is done fine.

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.

Android :: Way To Include Other Java Source Projects In Droid Project?

Sep 18, 2009

Is it possible to include other Java source projects in Eclipse into an Android project? Normally for a regular Java project you do this by adding the other project to the build path and including it in the Project References. This same approach lets the code compile, but when the app is deployed to the emulator, it throws a VerifyError when I try and instantiate classes from my other project. Is this possible with the Android SDK? Do you have to build them to jars and include them inside your Android project like this? I know this works, but just involves more steps to do this.

Android :: ADT Causing CDT To Build All C Projects On Android Application Launch?

Aug 27, 2010

I doubt there are too many people who run CDT in eclipse for native apps also with ADT installed for Android, but in the off-chance that someone here knows anything about this, my problem is that any time I run any android app, my C builder kicks in for projects totally unrelated. I have no idea why and have been digging through settings on everything, unable to find out why. All I can think is that the ADT pre-launch process triggers it via a refresh or some kind of catch- all type call in eclipse API land that I'm unaware of. Does anyone know anything about this? It's very annoying to have a C builder run for a different project than the one you're working on every time you launch the app.

Android :: Android Eclipse Test Projects Cannot Be Used With A Project Being Built

Mar 24, 2010

An Android Java project placed in a git repository and built in an Android tree in /packages/apps needs to have the project files located at the root of the git repository.This is problematic for creating a complementary Test project, which should ideally be included in the same git repository so commits are atomic for both code and tests. Eclipse gets very unhappy if you include the Test project as a subdirectory.Is there an appropriate approach for dealing with this other than creating a second repository?

Android :: Multiple Dependent Android Projects In Eclipse

Jun 14, 2010

I just started to play with android dev and java+eclipse is pretty new to me. I managed to create simple project and run it on my device. Now I want to create simple game (more of them actually) and I would love to use shared code base for all of them (game loop, initialization, etc..). Problem is that I have no idea how to correctly do this. I created android project called engine with all basic stuff that I need and made it work on device. Now I tried to create another project in same workspace called mygame. Main class (activity) of mygame is MyGameApp which inherits from EngineApp (main activity of my engine project) which inherits from Activity. I added engine project into required projects in mygame build path tab in properties. Problem is that when I try to run this project it crashes on ClassNotFoundException trying to find my MyGameApp class.
