I have a Android Lib Project which has a number of libraries (jars) added in /lib folder.
Now, I have written a Android Test Project to test the APIs of the Library project and I added the jar of the Lib project inside this test project.
Everything complies fine but when the code, in the Library project executes, which uses the jar file, I am getting a NoClassDefFoundError.
Could someone please help me with this issue?
Please do let me know what other details would be required from my end.
Thanks
Try to Clean Project and Run it again.
Try this way,
Right click on your project --> select Build Path --> go to Order and Export Tab
Check all the libs you added here and done.
I added the Google Gson jar file to my Android project by copying and pasting the gson-2.2.4 jar file to the libs folder and then right clicked on the Jar file and then select Build Path > Add to Build Path(I followed this tutorial). Then everything worked fine for me with this jar file, but after pushing to github, when my friends pulling this project, they said that all code relevant to that Gson jar file shows errors. How could I fix this?
Problem 1 : Jar doesnt exist. You probably forgot to add, commit and push your changes to github after adding the jar.
Problem 2 : Jar exists but unrecognised. Ask your friends to remove the existing library from java build path using project properties and add again.
You can create a library project which contains the jar file, and then add this library to your project.
Create library project in eclipse:
File->New->Android application project->Next->Check Mark this porject as a library,
uncheck Create custom launcher icon and Create activity->Finish
Add the library to your project:
Right click your project->Properties->Android->Add->Select the library project you created
->Apply->OK
After finishing these two, you should be able to use Gson, and when pushing your project,
remember to push the library project as well.
i dowloaded from here:
http://sourceforge.net/projects/redpin/files/release-3.1/RedpinAndroid.zip/download
i am using win8, ECLİPSE eclipse-standard-kepler-SR1-win32
i imported project and googled this problem. I tried project > clean section , it didnt work.
and also i tried properties > java build path > add library > jre system library for adding redpind library , it didnt work either. how can i solve this problem? thank you.
errors is:
The project cannot be built until build path errors are resolved
Project 'RedpinAndroid' is missing required Java project: 'RedpinCore'
these are classes
this is properties>buildpath
this is error page
This project depends another project named RedpinCore, so in order to build this, you need to reference the place where RedpinCore project resides, so that your project can find needed class definitions. Instead of this, you can remove this dependency, and add this jar to your classpath. The same classes can also be found in this.
Right click on your project Build Path/Configure Build Path...
Under Projects tab, right click on this project dependency and remove it.
Then copy the jar to your project and add it to your classpath.
I downloaded twitter sample application in AndroidTwitterSample repository and imported my eclipse. I am trying to run that sample application and i got the error: java.lang.NoClassDefFoundError in logcat.
The error is based on jar file missing.you must place jar files rite place.
Create a folder named libs inside the root directory of your project and put twitter4j jar inside.
Then include new jar via Project Properties -> Java Build Path -> Libraries -> Add Jars.
Remove any old reference to twitter4j jars.
Clean and launch.
I hope this will helpful to you.
see my post- No class defination found error even if there is no issues & let me know if this not working in your side.
I have a problem that I want to reference with another android project, I am generating jar of one project and included that within another project but there is an error as Error generating final archive: found duplicate file for APK: res/values/strings.xml
How it can be resolved?
Convert one project to a library project and reference it from the other project.
Maybe you want to use an android library project.
Go to the projects preferences and check "Is library project".
On the main project, simple add the library project you just created.
That should resolve this.
