jar file problem in android

i am trying to design an app on the basis of a java project according to that java project it has lot of jar files. when i tried converting the code's to an android i don't get much error but when i added the jar files used in that java net beans projects, there is no error but in the console it shows as "Dalvik errror......"

When i searched through google i found one of them saying remove the jar file. How to solve my problem please开发者_如何转开发 help me friends.....

Right-click your project in Eclipse, click Properties. Go to Java Build Path and then click the Libraries tab. You should have "Android " and "android.jar". Delete "android.jar".

If the answers in "Conversion to Dalvik format failed with error 1" on external JAR are not satisfactory its better to remove the unwanted jar file. It will remove all the errors immediately
