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.

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?
