Figure 5-1. Activity life cycle

When switching from stopped to running state onCreate method will no be executed! This method will be executed only once.

Paused state / Stopped state

It says: "The Activity Manager calls onPause() when putting
your application into the paused state, but we don’t use that hook to perform any activities
in this book" and then
"The Activity Manager calls onStop() when putting your application
into this state, so it is wise in this method to do anything you need in order to
save the state of your app, such as writing data to disk or a database"

ITS strictly vice versa! Android can kill activity and onStop method can never be called so in all google docs its directly says that you should save state in onPause since it can be the last methods in your app life cycle.

2nd paragraph in the section titled "The StatusActivity Java Class"

"The class is part of the com.marakana.android.yamba Java package, and as such is part of that directory."

I believe the package name is just com.marakana.yamba instead of com.marakana.android.yamba.

2nd paragraph in "The StatusActivity java Class" section

The package is listed as com.marakana.android.yamba, but probably should be com.marakana.yamba instead, in order to match what is entered for the Package Name in Figure 7-6 (pg. 93) and is shown in the Package Explorer in Figure 7-9 (pg. 97).

2nd-to-last paragraph

The line with reads: "We no longer need res/layout/activity_status.xml" should read "We no longer need res/layout/new_activity_status.xml".

Example 9.3

The SettingsFragment class is missing "implements OnSharedPreferenceChangeListener", and the code fails to compile without it.

United States

In Example 9-3, the class definition for SettingsFragment needs to implement OnSharedPreferenceChangeListener. The definition should read:

public class SettingsFragment extends PreferenceFragment implements
OnSharedPreferenceChangeListener {

The implements clause is missing.
