I am creating an application that needs two icons. (Is this possible?)
The main icon that is created by default, will launch the application. In this application, there is a "Enable/Disable" button (toggle button).
When this button is on enable, a 2nd icon (shortcut button to do another task) must be made visible on home screen.
And i want to code a onClickListener() on the new shortcut icon. i.e. When this new shortcut icon is clicked, without launching any activity, that particular action must be performed.
i.e. The app should not open but perform its assigned task.
Example: Activity A has a toggle button: if this button is enabled, a shortcut icon is created on homescreen. When this shortcut icon is clicked, the wallpaper of phone changes without any activity being launched.
How to change wallpaper randomly without opening any activity.
Any views about how this can be achieved?
I must make something like that.
I run my application and press button "Create widget" and the widget is created on Home screen.
I don't know how to do it, Just i know how to take widget to home screen when i choose my widget in widgets menu and write text what i want in this widget
And I know how to run ConfigureActivity on my application but when i writte some text and press add "widget" it don't create. I think i don't have any id's to create widget but how to get that? Random or something.
I used in Android Studio New > Widget > App Widget.
I run my application and press button "Create widget" and the widget is created on Home screen.
This is not possible. The only app that can add an app widget to the home screen is the home screen itself.
I have noticed the splash screen does not display when user clicks the middle button on a real device to quit an application but if user selects back button from main menu to quit app and relaunches the splash screen will display.
Question is what function is the middle button performing compared to the back pressed and is there a way to ensure the splash screen is displayed when the middle button is used to quit an application.
Thanks.
The HOME button takes the user to the home screen (also called the Launcher). The BACK button by default finishes the current activity, which usually results in the user ending up on the previous activity he was in, until he reaches the home screen. The difference is BACK will explicitly finish an Activity, whereas HOME will not.
When using a floating view (TYPE_PRIORITY_PHONE) how can the Home button be intercepted?
This behaviour is demonstrated in Facebook's "chat heads" where a conversation (which isn't an Activity) is collapsed on a home button click.
You could poll the top running app, and determine when it changes. This will detect the first home press, but if the users is already on the home screen, you will not detect it.
I want to add a button on the home screen and want to code in the click event of that button.

Thanks in Anticipation.
I don't think you can create a button on the Home Screen on-the-fly by coding. In my book, the only way to get a button on the Home Screen is if the user adds it as a widget.
If you are using xml layout for it add the button widget you needed and set it's visibility by android:visibility="gone",when you clicked the first button to activate the button to display,make it to visible by getting the id of the corresponding button
for eg: btn2.setVisibility(View.VISIBLE);
