Activity is an application component that provides users with a visual interface for convenient operations, such as calling, taking photos, sending emails or browsing maps. Each activity provides a visual window, which overwrites the entire screen, however, in some cases, some smaller windows may float on another window. Next, we will add a new Activity for the Android app. Step 1: Create a class that inherits the Activity, such as MainActivity. Pac

Alarm Controller demonstrates how to use Alarm events in Android applications. Its functions are similar to java. util. Timer and TimerTask. However, Alarm can execute a Schedule task at the specified time even after the current application exits. AlarmManager is used to manage Alarm events and supports one-time execution or repeated execution. Like most Android services, AlarmManager uses getSystemService

The method currently described is only used to store some simple data. If you want to store relational data, it will be more efficient to use the database. For example, if you want to store the scores of every student in the school, it's best to use the database, because you can query a student's specific score. Furthermore, the use of a database can preserve the integrity of relationships between different data. Android uses the SQLite database syst

The method used for thread threading in Android is the same as the Java SE. Like most OS systems, Android also has a main thread called UI thread. UI Thread is primarily used to distribute messages to the appropriate widget, including drawing (Drawing) events. UI thread is also the thread used to handle user interaction events. For example, if you press a button on the screen, the UI thread notifies the cor

Of course, this will bring about a new problem: inter-process communication, of course, because offline download and modules between applications are relatively independent, this problem is relativ
