Android :: Compiling Project In Eclipse 3.4.2 - Cannot Be Built
Sep 3, 2010
While compiling android project in eclipse 3.4.2, am getting The project cannot be built until the build path errors are resolved. I got a temporary solution from the blog http://www.scottdstrader.com/blog/ether_archives/000921.html
The resolution was to force a resave of the selected projects (and their .classpath files):
Open the project properties
Select Java Build Path > Libraries
Add a new, arbitrary library (to be deleted later) > OK
Wait for the workspace to refresh (or force a refresh of the project)
The error(s) will go away
Remove the dummy library
The only other references I could find were to make minor alterations of contents of the .classpath file.
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?
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.
The last couple of weeks, my app is very slow compiling changes when the resources are modified in the project. Doesn't matter if it's strings or layout. Sometimes it takes as long as 30 seconds for the changes to apply. Compiling just the .java files are as fast as ever.
I used to have slowdowns after I having Eclipse open for the whole day, but restarting Eclipse always fixed that. Not this time. All my Eclipse and Android software is up-to-date. Has anyone experience this or have any suggestion as to what could be causing this and a fix? It's really cutting into my productivity.
I've followed the steps given in the Android Developer Blog to generate a build.xml for building releases for an Android Application. I need to do a custom compiling so I have overwritten the target compile of the ant_rules_r3.xml as it is said in the generated build.xml.
The script works fine and generates the apk, but the problem is that Eclipse shows an error because it cannot find targets -resource-src, -aidl and -pre-compile (which are loaded when executing the script but are not really present on the build.xml). As there are these errors I cannot work with the project in Eclipse.
How can I skip the validation of this single file in Eclipse?
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.
I download android source and build a sdk from it (via make sdk). I have also installed ADT on my eclipse. My question is how can I setup ADT to point to the SDK that i built (it keeps saying it can't find the 'tool' directory and then it can't find the 'adb' under tool).
I am new to Android Development. Actually i am iphone developer and i am learning android developer. I installed android and eclipse and i run one project successfully.Now problem is that after creating project, it doesn't appear in eclipse. So can anyone plz tell me that how can i open project into eclipse.
I'm completely new to Eclipse/Java/Android programming, so this might sound like a dumb question, but I can't open the project I was working on last week. it's the "HelloWorld" project.I'm very familiar with Visual Studio so I've been looking for something like a project file/solution or a way to open a directory in Exlipse, but I'm having no luck and am completely lost.
I tried to build test library and test app with latest ADT and Eclispe however Eclipse complains on each reference I made to library classes from my test app. This is what I did:
1. created Test Library Android project, marked it as "Library" (package name "test.library.lib") 2. created Test App project (package "test.library.app") and set it to use Test Library 3. Test Library got LibActivity class which simply referes to lib_main.xml layout 4. I defined that activity in Test App manifest file:.............
I have an android project that uses ant to build, is it possible to import this ant project in eclipse IDE?
update : There is an option to create project using ant build.xml in eclipse File->New->Project->Java->Java project from existing ant Buildfile. and if the build.xml file is selected it show error "Specified buildfile does not contain a javac task"
I would like to run a custom shell script upon clicking Build Project in Eclipse. I tried modifying the "compile" section in build.xml, but my script is not getting run. Invoking ant debug on the commandline works, however.
When I create a subfolder in the layout folder, and drag an xml file to it, the generated R file doesn't seem to show the subfolder. a) is there a way to change that b) is the file and file structure still picked up by SVN and c) so, if I do it that way, can I still just refer to the object using layout?
This is a two-part question about adding a third-party library (JAR) to an Android project in Eclipse. The first part of the question is, when I try to add a third-party JAR (library) to my Android project I first get the problem of Error parsing XML: unbound prefix
because I'm trying to use a class from that JAR (and need the prefix somehow defined). What's going on?Second, (after fixing that--the answer is given below), my application doesn't work on Android and I discover via the debugger (LogCat) that the class I'm attempting to consume doesn't exist.
Why, when I get no compilation or linker error in Eclipse, does it have this problem on the emulator? These two questions are rhetorical for I'm going to answer them myself below. Other posts in this forum creep up to the problem and elsewhere there is discussion, but I feel that I can be more explicitly helpful for the next guy to come along.
I am trying to create a library project, I've got things working up to the point of building the application that depends on the library, but installing the APK on the emulator always fails, because the shared library is not there. (The documentation indicates that the ADT would include the library in the APK of the dependant application, but this is clearly not happening.) BTW, I'm using the package name of my library project in the application's "uses library" tag. Is this correct? The documentation is completely silent on this subject. I've been banging my head against this for two days nowanyone has gotten a library project to actually work.
I'm clearly missing something simple, but after nearly an hour of trying to figure it out, I'm still stuck. I have an external jar file containing classes I want to use in my project. No problem, right? I just followed the instructions at
That is, I used the Properties->Java Build Path->Libraries panel to add the jar to my project as a library. But it doesn't work. The external library is being included in the compilation classpath, so everything compiles correctly, but the external classes aren't actually getting included in the apk. When I try to run my app, it immediately crashes with a java.lang.NoClassDefFoundError. And looking at the apk, I see it's only 20K, whereas the external library jar is over 200K.
I've noticed that then I use "clean" from Eclipse project menu on my project I receive following error [2009-02-19 09:55:02 - MyListView] no classfiles specified [2009-02-19 09:55:02 - MyListView] Conversion to Dalvik format failed with error 1
Project doesn't use any external jars and rather simple. If I uncheck build automatically and build it - it builds and runs just fine. I'm on MacOSX 10.5.6 and JDK 1.6.0_07. And latest android SDK ( android-sdk-mac_x86-1.1_r1.zip 79046151 bytes becf0f1763d61eedce15d2a903d6c1dd )
I had a project working in Eclipse completely, but after compiling it with ant in order to use Proguard to obfuscate the code the entire project fell apart. The project consists of a single package containing two main activities and 4 helper classes to handle databases and such. After using ant the activities work fine but Eclipse cannot find the helper classes and won't build. Even if I explicitly import the classes the error I get is The import com.ts.routeTracking.DataHelper cannot be resolved while further mentions of the class get the error DataHelper cannot be resolved to a type. How can I get Eclipse and ant to work together?
This happened to two programs of mine now and makes absolutely no sense. It usually comes about when I'm adding a resource file (in this case, a menu). In the package explorer: -the project name has a small red x, indicating that there is an error in one of its files -none of the sub-folders or files have an x or show any red highlights None of my code has errors! Ocasionally, I see this: [2010-09-02 16:09:20 - FallDown] 'default' is not a best match for any device/locale combination. [2010-09-02 16:09:20 - FallDown] Displaying it with 'Normal, Not Long, Landscape, Medium Density, Finger, Soft, Qwerty, Trackball, 480x320'
As part of the Android application I am developing in eclipse, I need to combine two packages from different projects into a single project. I tried copying the files in the package of the second project under the src folder of the first folder and copied other files required for second package into the res folder of the first project. But the auto-generated Java files i.e R.java doesn't get updated on copying. I tried right clicking on the project and clicking on Android Tools -> Fix Project Properties. But nothing changed.
