Question

My android project crashes when I try to move from one class to another, and I always get the same error. I have possibly removed some files when I was adding external some jars.

Here is my LogCat:

(Those package and activity names are not the one I use)

All of my applications in Eclipse crash with quite similar LogCat messages. Does anyone know what is wrong?
The project also does not launch from the menu or my phone. When I try to do so, it says that the application is not installed on the phone.

It looks like you need to add “internet” permission to your AndroidManifest.xml:

android.permission.INTERNET E/AndroidRuntime(306): at 

For example:

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
