This is the error Iam getting in my apps in adt 20.....if i am using external jar.
回答1:
There are only a few reasons you will ever get this error:
- The class genuinely doesn't exist. If you are using code from an official example and getting this, make sure you have the latest build of the library
- You have not added the jar to your build path. To fix this, right click on the jar in Eclipse, and do Build Path ► Add to Build Path.
- Your jar is not in the /libs folder. This happens when you have added the jar to the build path, but newer versions of ADT need it to be in /libs. Put it there and re-add it to the build path.
- Your JAR file must be build compatible for Android (actual Java 7 compiled classes are not supported!).
回答2:
Remember always put all external jars in your apps libs. create libs folder where AndroidManifest.xml exists. Then refresh your project in eclipse.
Then do as follows:
- Right click on your project in Eclipse
- click on properties.
- on properties window click on JavaBuildPath
- select Libraries tab
- click AddJARs button & add the external jars from your project's lib

See this thread. They seem to be describing a problem very similar to yours. Maybe you lack some permission in your manifest for the activity you are trying to start?
