Start a FragmentActivity from a normal Activity.. java.lang.NoClassDefFoundError

I am trying to start a FragmentActivity from a normal Activity, and I get this java.lang.NoClassDefFoundError in log, while the app crashes.

Should I change anything in manifest to be able to use a FragmentActivity in my app?

Has anyone else come across this error? How did you fix it?

The android-support-v4 library contains a bug.

So, make a new project with android version 4.2.2. Copy the file which is android-support-v4.jar, and paste in your project.

I solve the problem this way!

The issue is noted here: FragmentActivity causing ClassNotFoundException

Please update the sdk tools. It should solve the problem.

Maybe is a stupid hint. But are you sure to have inserted the FragmentActivity into your Manifest file?

If so try to insert this into manifest:

<uses-sdk
    android:minSdkVersion="4"
    android:targetSdkVersion="8" />
