I am just using the <code>java.net</code> package.
Here you can do the following:

String myUrl = &quot;http://stackoverflow.com&quot;;
URI myURI = new URI(myUrl);

If you are using Kotlin and Kotlin android extensions, then there is a beautiful way of doing this.

<pre><code>val uri = myUriString.toUri()
</code></pre>

To add Kotlin extensions (KTX) to your project add the following to your app module's build.gradle

<pre><code> repositories {
 google()
}

dependencies {
 implementation 'androidx.core:core-ktx:1.0.0-rc01'
}

You can parse a String to a Uri by using <a href="https://developer.android.com/reference/android/net/Uri.html#parse(java.lang.String)" rel="noreferrer">Uri.parse()</a> as shown below:

<pre><code>Uri myUri = Uri.parse("http://stackoverflow.com");
</code></pre>

The following is an example of how you can use your newly created Uri in an implicit intent. To be viewed in a browser on the users phone.

<pre><code>// Creates a new Implicit Intent, passing in our Uri as the second paramater.
Intent webIntent = new Intent(Intent.ACTION_VIEW, myUri);

// Checks to see if there is an Activity capable of handling the intent
if (webIntent.resolveActivity(getPackageManager()) != null){
 startActivity(webIntent);
}
</code></pre>

NB: There is a difference between Androids <a href="https://developer.android.com/reference/java/net/URI.html" rel="noreferrer">URI</a> and <a href="https://developer.android.com/reference/android/net/Uri.html" rel="noreferrer">Uri</a>.

Java's parser in <code>java.net.URI</code> is going to fail if the URI isn't fully encoded to its standards. For example, try to parse: <code>http://www.google.com/search?q=cat|dog</code>. An exception will be thrown for the vertical bar.

<a href="https://github.com/EricEdens/urllib" rel="nofollow noreferrer">urllib</a> makes it easy to convert a string to a <code>java.net.URI</code>. It will pre-process and escape the URL. 

<pre><code>assertEquals("http://www.google.com/search?q=cat%7Cdog",
 Urls.createURI("http://www.google.com/search?q=cat|dog").toString());

If you're just going to use it with an HttpGet for example, you can just use the string directly when creating the HttpGet instance.
