How to open a URL in a browser from your Android app

Motivation

Sometimes you want to redirect the user from your app to the website for e.g. imprint and data protection info.

So it can be helpful to open up a website directly from your app.

Implementation

In Switch between activities you learned that the standard way of switching between activities is an intent.

The same goes for open up the browser on your phone. The intent is called the “ACTION_VIEW”

import android.content.Intent
import android.net.Uri
val browserIntent = Intent(Intent.ACTION_VIEW)
browserIntent.data = Uri.parse("https://prestissimo-guitar.com/")
startActivity(browserIntent)

Passing data between AndroidActivities

Sending data

private void openVideoActivity(String video) {
    Intent newActivity = new Intent(this, PlayerActivity.class);
    newActivity.putExtra("videoId", video);
    startActivity(newActivity);
}

Retrieving data

final String videoID = getIntent().getExtras().getString("videoID");

In Kotlin it looks like this:

val intent = Intent(this, NewActivity::class.java).apply {
    putExtra("EXTRA_MESSAGE", "Test 123")
}
startActivity(intent)

Retrieving

val message = intent.getStringExtra("EXTRA_MESSAGE")
