Sorry, (application name) is stopped. Eclipse / Android

I am new to eclipse and want to know how to save this message

Unfortunately, (App Name) has stopped."

from showing every time I run a test application in my AVD. I try to make a LayView Layout and Eclipse does not show errors. So how can I fix this and how can I find out what is the problem if Eclipse does not detect problems?

(Here is a copy of my Logcat)

Looking at your LogCat and your manifest, you can see that the name of your activity class is different from the name of the class represented inside the manifest file.

So, to fix the problem, change this line in the manifest

 android:name="testing.android.application.three.MainActivityThreeActivity"

for

 android:name="testing.android.application.three.MainActivityThree"

This can solve the problem!

Always remember that the AndroidManifest file β€œcontrols” your application. Each service and activity that you want to use, or all the permissions necessary for your application, you need to register in your manifest file and do it correctly, otherwise you will encounter such failures.
