3. Libraries The Android UI toolkit is not thread-safe. What does it mean that the library is not thread-safe and what is true about the Android library? You don't have to worry about where you call the UI toolkit methods from. You can not reliably call operations in the library from more than one thread at a time. The android library does not allow you to call from any thread other than the UI Thread. If you put a lock to protect the code you can call the UI toolkit from anywhere. 4. Application Environments .. It is not uncommon for Windows and Mac applications to stall the user interface thread during network operations. Why is this more of an issue in Android than in those environments? In windows and the Mac you can easily have more than one applicatin open at a time. If a program stalls you can easily go do something else. Android has more of a one-at-a-time usage model, so stalling the interface pretty much stalls the user. O 000
