Call Intent - Android Studio - Kotlin

Open Call Intent with Phone Number using Android Studio and Kotlin

We will use intent to open the dialer with the phone number the user entered. In this example, we will input a phone number using an input field, i.e., EditText, and open that phone number in the dialer screen by clicking the button.

>> Check for Java
>> Check for Kotlin
>> Check for Compose

Code Snippet:

val intent = Intent(Intent.ACTION_VIEW, Uri.parse("tel:${Uri.encode(phone)}"))
startActivity(intent)
