java - Android app won't launch (using Eclipse)

Question

Working on an Android app for the first time. It is not launching and because it's my first app, I don't understand the errors. Here is the console output:

Appreciate all help

Answer 1

Your case, have this error:

android.util.AndroidRuntimeException: You cannot combine swipe dismissal and the action bar.

Change target Version:

android:targetSdkVersion="21"

TO:

android:targetSdkVersion="19"

See here

targetSdkVersion setting
