I have been trying to invoke another activity from the mainactivity class with the code: 

```
startActivity(new Intent("intent filter name here"));

```

However when I debug the application when it gets to this line I get a source not found message in the class file editor that says the source attachment does not contain the source for the file ClassLoader.class. There is an option to change the attached source "android.jar" but there is only one such file under the\_targetAPI folder. How can i fix this?
