How did you import the backendless library into your project?
i copy pasted backendless jar file in my lib folder…then refreshed project from eclipse.
then select proj …righ click…build path…configure…add external jar…
same error is happening if i run code of code generator for registration - login - password revovery
At the top of the LogCat window it shows “NoClassDefFoundError: com.backendless.Backendless.”
It means that backendless.jar is not included into the deployment of the app. That’s the problem you need to solve.
Any particular reason you’re not using Android Studio??
Hii Sir…
I have intel Core2 Duo cpu with 2 gb RAM…Android studio not works properly with it…
And how can i include backendless.jar into the deployment of the app???
Regard,
Fagun
Sorry, I am not familiar with Eclipse. I am surprised someone is actually still using it.
I am pretty sure if you ask on stackoverflow “how to include a jar dependency into Android project?”, there will be people familiar with Eclipse who would help you.

Mark
Stackoverflow shows it is correct how i imported backendless.jar.
Then why it is not included in my deployment sir?
Fagun,
If I knew anything about Eclipse, I’d love help you. Unfortunately, I know nothing about that environment. Just by looking at the error, I see that the class is not found, which means the jar is not available.
Regards,
Mark
ok mark…problem will be solved if i use anroid studAny way thanks for prompt support…
i will try it for android studio
Thanks you sir

hello sir… i have solved that error you pointed…now i am getting this error…can u help me??
Looks like it cannot find your own classes…
If your computer can run Eclipse, surely it can run Android Studio… I suggest you switch to it and save yourself a bunch of headache…
ok sir…i am changing to android studio…but can i take my whole project from eclipse to studio?
