getSupportFragmentManager() is undefined

Question

I\'m getting the following error: \"The method getSupportFragmentManager() is undefined for the type new View.OnClickListener(){}\" in my fragment

Answer 1

I had a similar problem loading a lesson project (https://developer.android.com/training/multiple-threads).

To resolve, I had to add an external jar (sdk/extras/android/support/v4/android-support-v4.jar).

Hope this helps.
