Simple Intent to change activity not working

Question

I'm trying to change activity by an intent like this to a fragmentactivity that opens a embeded Google Map:

Intent driver = new Intent(getApplicationContext(), DriverActivity.class);
startActivity(driver);

But the app crashes, I've recently moved from Eclipse on my Windows to a Eclipse on Ubuntu. I can't see why the app won't change activity. The debugger opens layoutInflater.class and the message inside that windows is: Source not found

What's wrong and how do I fix it?

By the way, don't use getApplicationContext() for this sort of thing... instead use a current context, like an Activity. — Pozzo Apps, Jul 04 '13 at 18:04

Use this :

Intent driver = new Intent(this, DriverActivity.class);
startActivity(driver);

Not working, I'm getting `07-04 20:20:26.138: E/AndroidRuntime(3953): java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable` but my class is registered in the manifest – timbillstrom Jul 04 '13 at 18:21
Make sure you have that class present in your activity file..Clean your project build once and try to rerun it. – Ponting Jul 04 '13 at 18:32
