Android-create shortcuts and determine whether a shortcut has been created

Generally, shortcuts are not automatically created after the android application is installed. Therefore, you can implement shortcuts when the application is started.

Permission required <uses-Permission Android: Name = "com. Android. launcher. Permission. install_shortcut"/>

The attribute of the activity corresponding to the shortcut to be clicked.

<Intent-filter>
<Action Android: Name = "android. Intent. Action. Main"/>
<Category Android: Name = "android. Intent. Category. launcher"/>
</Intent-filter>
<Intent-filter>
<Action Android: Name = "android. Intent. Action. create_shortcut"> </Action>
</Intent-filter>

How can I determine whether a shortcut has been created? Because the shortcut information is saved in the favorites table of launcher. dB of COM. Android. launcher, You can query this table to obtain it,

Permission required <uses-Permission Android: Name = "com. Android. launcher. Permission. read_settings"/>

The following is an example:

</P> <p> Import android. app. activity; <br/> Import android. content. contentresolver; <br/> Import android. content. intent; <br/> Import android. content. intent. export cuticonresource; <br/> Import android. database. cursor; <br/> Import android. graphics. bitmapfactory; <br/> Import android.net. uri; <br/> Import android.
