When you encounter the error message “Failed to launch because the scheme does not have a registered handler,” it means that the URL scheme (protocol) you are trying to use does not have a corresponding app or program registered on the device or operating system to handle the specified scheme.
URL schemes are used to launch specific applications or actions using unique protocol identifiers. For example, “http://” scheme is used for web browsing while “mailto:” is used for launching the default email client for composing new emails. If you try to open a URL with a scheme that is not supported or registered, you will receive the mentioned error.
Here is an example to help you understand better. Let’s say you have a URL with a custom scheme called “myapp://” that is intended to launch your mobile application. However, if the device or operating system does not have an app registered to handle that specific “myapp://” scheme, you will encounter the error.
To resolve this issue, you need to ensure that the app or program associated with the URL scheme is installed on the device and registered to handle that scheme. For our example, you would need to make sure that your mobile app is installed on the device and correctly registers the “myapp://” scheme.
Additionally, it’s important to handle any errors or exceptions related to unsupported URL schemes gracefully in your code. You can perform checks to verify if the scheme is supported before attempting to launch it, and provide suitable error messages or fallback actions.
