However, this migration is not guaranteed to work, as there might not be mapping rules general enough to cover all the custom types. If you pass the -r flag, the utility runs in reverse mode.
In this mode, the utility converts AndroidX APIs to the support library equivalents, instead of the other way around.
Reverse mode is useful, for example, if you are developing libraries that use AndroidX APIs, but also need to distribute versions that use the support library. The following example runs the utility in reverse mode on the library myAndroidXLib.
The Jetifier tool uses a config file to map support library classes to their AndroidX equivalents. If necessary, you can make a custom config file that alters this mapping. You can even add new classes to the mapping that are not actually members of the support library; for example, you might modify the mapping to replace one of your own classes with a successor class written to use AndroidX.
To use a custom config file, first extract the file default. Make any necessary edits to your copy of the config file, and pass your file to the utility with the -c flag.
For example:. Content and code samples on this page are subject to the licenses described in the Content License. Android Studio. Download What's new User guide Preview. Meet Android Studio. Manage your project. The suggested workaround is to create a machine user — a dummy GitHub account that is granted write access on a per repository basis. You can also authenticate with your GitHub username and password using the user and password options. This is not recommended as it allows full access to your GitHub account but is simplest to setup.
This example authenticates using a username and password. You can configure this in Repository Settings or via your. This example includes all files in a given directory. You can deploy only when certain conditions are met. See Conditional Releases with on:. Sometimes you want to run commands before or after releasing a gem. These will only be triggered if Travis CI is actually pushing a release. The following options from. As you navigate between composables, the content of the NavHost is automatically recomposed.
Each composable destination in your navigation graph is associated with a route. Creating the NavHost requires the NavController previously created via rememberNavController and the route of the starting destination of your graph. You can add to your navigation structure by using the composable method. This method requires that you provide a route and the composable that should be linked to the destination:.
To navigate to a composable destination in the navigation graph, you must use the navigate method. To navigate from a composable within the navigation graph, call navigate :. You should only call navigate as part of a callback and not as part of your composable itself, to avoid calling navigate on every recomposition.
By default, navigate adds your new destination to the back stack. You can modify the behavior of navigate by attaching additional navigation options to our navigate call:. See the popUpTo guide for more use cases. Navigation compose also supports passing arguments between composable destinations.
In order to do this, you need to add argument placeholders to your route, similar to how you add arguments to a deep link when using the base navigation library:.
By default, all arguments are parsed as strings. You can specify another type by using the arguments parameter to set a type :. You should extract the NavArguments from the NavBackStackEntry that is available in the lambda of the composable function. To pass the argument to the destination, you need to add the value to the route in place of the placeholder in the call to navigate :.
For a list of supported types, see Pass data between destinations. Navigation Compose also supports optional navigation arguments. Optional arguments differ from required arguments in two ways:. This means that all optional arguments must be explicitly added to the composable function as a list:. Now, even if there is no argument passed to the destination, the defaultValue of "me" will be used instead.
The structure of handling the arguments through the routes means that your composables remain completely independent of Navigation and are much more testable. Navigation Compose supports implicit deep links that can be defined as part of the composable function as well.
