Android :: Importing Existing Projects To Android
Jul 7, 2010
I generated a standard Android under Eclipse (using the plugin) and I imported code from an existing project (J2SE-based). I was able to iron out all the complaints from the Android SDK 2.1 (compile errors). However, the runtime (emulator startup) the IDE displays a message saying that the project contains errors, please fix them before running it. But all that there is there are warnings - is Android "unforgiving" about Java warnings or is there something else I should be looking into in there - no class has any compile errors.

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).

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.

I'm trying to import an Android project into my Eclipse workspace, using existing source code. When I point Eclipse to my existing source location, it doesn't populate the Build Target area on the New Android Project dialog. Why isn't it letting me pick a build target?

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.

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?

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.

I have several projects which contain the same strings. Is there a way to share the strings.xml file between projects? I have a library project where I put shared .java code which has a strings.xml, but is the data in the library strings.xml added to the including project's strings.xml at build time?

Just got the incredible and I need an app that will help me with work because that's the main reason I got a smartphone. I use to use Google Apps spreadsheets to keep track of all my writers projects, but it seems that would be harder on the incredible. Basically I need something where I can know which client the project is for, which writers are working on it, a short description of the project, if it's done, been paid for, etc. Any app that could help me with this?

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.

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 ?

For some unknown reason when I now try to create a new Android project in Eclipse (Ganymede running on Windows) it fails to link to the android.jar in the SDK (1.0_r1). This has never happened before, and all my existing projects continue to resolve Android components just fine.
Error: "Cannot create linked resource '/.org.eclipse.jdt.core.external.folders/.link0'. The parent resource is not accessible."

How can I attach Java source to an Android project? I'm able to browse java source for a Java project, but not for an Android project. I modified project properties and add Java source in "Libraries" section, still not working.

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".)

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?

As far as I understand, all the built-in standard apps like (email, music, calendar etc) are built using the same API. So I should be able to import a project like mail / music etc without checking out the full source repository of android. 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.

This tip comes in courtesy of Mark, who was kind enough to help out fellow Android addicts get their contact syncing issues sorted out. While it?s easiest to just use gmail to sync contacts and calendar, it?s certainly not required. Here?s how you can back up your contact list for easy retrieval anytime you need them. Open your contacts application Make sure All contacts are visible, unless you only want to back up certain groups.
Hit the menu button
Hit the Import/Export button
We can verify that this works on HTC Sense phones, as well as the new Galaxy S series phones. If you?re using something a bit more vanilla, you will have an option to do the same thing but using your SIM card (through SIM Manager in the contacts menu) instead of the microSD card. Lastly, if you?re using the latest CM6, you have the option to do both!

I've been largely pleased with the Droid after about 12 years using Palm devices. The exception is the inability to easily, quickly import the 550+ Memos I've authored over the years. Plenty of apps will import one huge memo, but none will import a csv file of ALL the memos. This includes OI Note. Does anyone have any experience successfully importing such a large number of memos without having to extensively edit? Or ideally, edit at all?

I am currently using the Droid48 as my engineering calculator -- one less item to carry around. I have not figured out how to transfer programs into Droid48 yet. The description of the program points to hpcalc.org for 3'rd party programs, but I have seen no documentation describing how to import them. Do you need to transfer using Kermit through the USB cable?

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.
