Question

I am trying to compile and run the project https://github.com/jitsi/jitsi-android on Eclipse by Importing.

I have imported the project successfully,Added External Jar files and Fix some of compilation errors.

When I try to run app, It is giving

Conversion to Dalvik format failed with error 1 Error on the console.So that I Clean the project, checked the all the jar files from Order and Export tab and build it again.

but it doesn't work for me.

Finally, I unchecked the all the libraries from Order and Export tab,build and run it again.

But still its giving me same error and my application is getting crashed every time i run it.

Any help will be appreciated , i really want to run this application.

Answer 1

I've had the same problem once.

Here is what I found out when I was trying to solve my issue:

• The error is caused when there are two Classes/Packages with the same name (For example when LibaryX has Class org.a.b.c.Sample and LibaryY has class org.a.b.c.Sample aswell)
• Different approaches which worked for some people (So if you have the error yourself, make sure to test following things out):

A) Two Libaries have the exactly same package/class-> Delete the class in one of the Libaries

B) One Jar is detected twice because it's for example in the project source folder and in the Java Build Path Libaries aswell

C) Updating Proguard often fixes it aswell (Put the new Proguard jars in [Android SDK folder]\tools\proguard\lib)

D) Cleaning the Project also helped many people (you already did that, so that won't be your solution)

When I had this issue myself it was caused because I did not follow the instructions of one of the libaries that I used. After following the libary instructions step by step, everything worked fine again.
