this manifest there, , app dont open . can explain me how set manifest activites? precus first open when app open. @ precus activity there intent when button clicked customize activity. why not working?

change line in file 

<action android:name="com.yair.guessit.precus" />

to 

<action android:name="android.intent.action.main"/>

then run it.
