Android - Activity Not Found Exception

Solution 1:

I know this is an old post, but it's on top of the google search at the moment, so for anyone who would come here later: ActivityNotFound can be caused by unhandled exceptions in your onCreate in the activity you're trying to create. It took me a while to notice that I was causing a nullPointerException there, because I wasn't looking for it.

Solution 2:

Did you list the activity (symtomRemedyActivity) within your AndroidManifest.xml file?

Solution 3:

Make sure you have added the following to the Manifest File

    <activity
        android:name=".YourActivity"
        >
    </activity>
