Develop: Let me think ...
Principle 1 - activity-alias
In AndroidMainifest, there are two properties:
In addition, there is an activity-alias attribute, which can be used to create multiple different entries. I believe that developers who have done system Setting and Launcher development should have seen a lot in the source code of the system.
Principle 2 - PM.setComponentEnabledSetting
PackageManager is a general class that can manage all system components. Of course, if Root is used, you can also manage all components of other apps. Some system optimization tools disable some background services in this way.
It's very simple to use:
According to the two flags PackageManager.COMPONENT_ENABLED_STATE_ENABLED and PackageManager.COMPONENT_ENABLED_STATE_DISABLED and the corresponding ComponentName, you can control whether a component is enabled.
Change Icon dynamically
With the above two principles, there is only a problem of thinking to realize the dynamic replacement of Icon.
First, we create an Activity as the default entry with the default image, and then create a double 11 activity-alias pointing to the default Activity with the double 11 image, and then create a double 12 activity-alias, Pointing to the default Activity with a picture of double 12... blah blah blah.
Wait, there is a problem with this, that is, 3 entries will be displayed on the Launcher, so by default, we will disable these activity-alias first, and then enable them when they are used.
OK, after disabling the default Activity and enabling the activity-alias of Double 11, the result remains the same as the default Activity, but the icon has changed.
Depending on the ROM, after disabling the component, after a while, Launcher will automatically refresh the icons.
Refer to the following figure for the effect.
