Use Intent to send messages From one component to another Text messageThis is a feature that we often use. android comes with a text message. The two activities in the two applications do not prevent intent from transmitting data. Add a piece of code to anotheractivity. It is not the previous

schematic diagram of the singleinstance is as followsWhen we see the jump from mainactivity to secondactivity, we re-enable a new stack structure to place the secondactivity instance, then press the back key again to return to the original stack structure , the lower half of the figure is shown in secondactivity again to jump to mainactivity, this time the system will generate a mainactivity instance in the original stack structure, and then back two times, notice, did not exit, But to return t

First to implement the function, or first from the API to find. See if there's anything you want. This is actually listening to the status of activity within the app. What to do?To an API location: http://www.android-doc.com/reference/android/app/Application.html　　Did you see that?

1. Create a NewActivity During desktop development, we can open another new window through a control event in a window. During web application development, we can also open a new page through a connection. By adding a new window to improve or enhance the software functions, how should we open a new activity in Android Application Development? 1.Add a new activity

activities can be started by clicking the icon on applicationlauncher on the home screen. The activity used to crop an image and append a file cannot be started from the main screen. They need a context runtime environment and cannot run independently.In fact, not all applications have icons and can be started on the main screen. Take a small application that is not commonly used as an example. This small application can replace the entry point funct

Android starts the activity anonymously and starts the system activity Generally, when we use Intent for activity jump, we all know the name of the activity to jump to, for example: Intent intent=new Intent(FirstActivity.this,SecondActitivy.class);startActivity(intent);When

The Android system calls the corresponding callback function to execute the code according to the different stages of the life cycle. The system has an ordered set of callback functions to start and destroy an activity. This section discusses what to do and what not to do in the callback functions for different life cycles.Understanding the callback of the life cycleIn the life cycle of an
