How to open the dialer in Android through Intent?

If you want to open the phone dialer in Android without making an actual call, you can use an Intent with the ACTION_DIAL action. This way, the user can review and modify the number before making the call, or even decide not to proceed with the call.

Here's how you can open the dialer:

Intent dialIntent = new Intent(Intent.ACTION_DIAL);
startActivity(dialIntent);

If you want to open the dialer with a specific number already filled in, you can pass a tel: URI to the Intent:

Intent dialIntent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + phoneNumber));
startActivity(dialIntent);

Replace phoneNumber with the actual number you want to dial.

You don't need any special permissions in the AndroidManifest.xml to use ACTION_DIAL.

// Inside your activity or fragment
