I created an emulator using API 17, and the app still crashed. I can't figure out how to get it working in the emulator.
1.) If you want to be able to run this app on an emulator targetting API 10 or older or to run this app on an older smartphone running Android 2.3.x or older than you need to import android.support.v4.app.Fragment
2.) If you are creating your own Fragment1.java and Fragment2.java make certain that the filenames are exactly with the first letter in uppercase and all other letters in lowercase. This is because of the lines in main.xml android:name="net.learn2develop.Fragments.Fragment 1
and android:name="net.learn2develop.Fragments.Fragment 2
3.) The app crashed unless the main activity extended FragmentActivity not just Activity.
