Special thanks to this StackOverflow answer by P-A for the core code. Non-default launchers may not display this changed icon.The original title and icon will show in many places throughout the OS.It will need to be uninstalled or reset back to the default. If you are trying to deploy an app that has had it’s alias changed since install, Android Studio will fail to launch it.The OS will then be unable to open your app, and display an App not found toast. Related to the previous issue, if you try to open the app via the icon during these few seconds, there will be a mismatch between the launcher shortcut and the manifest.If you programmatically change your alias, it can take a few seconds for the launcher to update.I noticed a few quirks during my experimenting with this, and I’d be hesitant to use it in a production app without extensive testing. Your activity should end up something like this:Įnum class ICON_COLOUR Īpp icons can then be changed with just setIcon ( ICON_COLOUR. This is so our aliases can use it instead. Note that this can take a few seconds to take effect, and almost certainly has strange side effects! Registering aliases in manifestįirst, remove the MAIN action ( ) from your app’s launcher activity (by default MainActivity). This will result in the OS only showing the remaining activated alias on the app launcher. However, we can define multiple aliases for our single activity, with the end result of multiple configurations of icon + title for our app.Īll of our activity aliases will define themselves as the starting point to the app, so we’ll need to disable all the ones not currently in use. MAIN action (which usually exists on your default activity) tells Android which activity should be used to start your app. Luckily, it’s pretty straightforward! Whilst this article is a detailed explanation of the solution, it is also available as a Gist, and an example project. Recently, out of curiosity, I discovered it was possible to change the app icon / name whenever you want, without an update. However, usually this icon is defined in your manifest, then never changes except through update. It’s what grabs the user’s attention first, identifies your app amongst the sea of competitors, and is the most important piece of visual branding. In Android, your app’s icon is a crucial part of your project.
