Why Do I Constantly Get Activitynotfound Exceptions?

I'm a novice Android programmer, and to help me understand how Intents really work, I wanted to put together a small Activity which would let the user call startActivity() with any

Solution 1:

I tried many different combinations, including "android.intents.action.VIEW" and "html://www.google.com".

android.intents.action.VIEW is not a valid activity action. You probably want to drop the s.

html://www.google.com is not a valid URL. You probably want to replace the html:// with http://.

Solution 2:

Check your logs with:

adb shell logcat

But I guess you are missing the definition of your Activity in your AndroidManifest.xml
