So, thoughts?

I was also trying to implement it and got the same error .After lot of effort I was able to run it but received the similar error as you have received .
I resolved the issue by
1:Close and start your eclipse .
2: copying the v4 jar of main project in all the library projects and deleting the existing ones .
The error comes due to mismatch of supportv4jar. Make all the supportv4jar of same version
3:after that Delete the gen and bin folder and clean the project and run .

I tried to run a google map v2 in an android device.But receiving same errors all the time. I couldnt solve it. Can anyone help me? [duplicate]

After Google Play Service update to version 13 I got an error

First of all, check if your source is where it is mentioned in the error log.
If it is, check if you've made any typing mistakes
If it still isn't working, it would be easier (In my opinion) to create a new project and rename what is missing (I've done this several times already and it has always worked) Of course, make sure you copy all of your code

It looks like you've missed out your Splash activity in your manifest.
<activity android:name=".Splash"/>
See if that line appears in your manifest, if not you should add it.

Initially, this application was working well. But after a few days, it stopped working giving the above error. I don't seem to understand what is wrong. Please help me.

You have done one of two things:
Renamed your activity package or class name and not updated it in the manifest
or
Changed your manifest to reflect an activity that doesn't exist
Check your manifest against the fully qualified class name for that Activity. Make sure they match. Then go to Project -> Clean and clean your project.

I think, you declared Activity in AndroidManifes.xml, and register it as default to launch in your application. But, you have no Activity with this name as you declared in manifest. Just correct activity name in AndroidManifest.xml

Here is the error:
java.lang.ClassNotFoundException: com.example.projectsample1.MainActivity
The MainActivity class of the projectsample1 Application was not found.
Try to clear the dalvik-cache if you know how to do it.
Otherwise, re-install the application.
Or if you are the developer of the application, make sure to change the name of the class in the Manifest.xml file if you changed the name of the MainActivity class.
