I'm attempting to add images from a URL to my android app but for some reason I'm getting an error message stating Unhandled exception type URISyntaxException. I believe I have misformatted my code somehow and I could use a bit of assistance figuring out what exactly might be causing this "Unhandled exception type URISyntaxException" error I'm getting.
Unhandled exception type URISyntaxException: httpRequest = new HttpGet(imgUrl.toURI());

URISyntaxException . This is a checked exception that occurs when you are trying to parse a string that represents a URI, but it doesn't have the correct format.
java.net.URISyntaxException. Checked exception thrown to indicate that a string could not be parsed as a URI reference.
An exception is a known type of error. An unhandled exception occurs when the application code does not properly handle exceptions. For example, When you try to open a file on disk, it is a common problem for the file to not exist.
The error is self-explanatory
Unhandled exception type URISyntaxException
Since, URISyntaxException is a checked exception you need to catch it as well.
} catch (URISyntaxException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
