Android Intent call number [duplicate]

Answer 1

Official Solution

Example intent:

public void dialPhoneNumber(String phoneNumber) {
    Intent intent = new Intent(Intent.ACTION_DIAL);
    intent.setData(Uri.parse("tel:" + phoneNumber));
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

Answer 2

For kotlin

    val intent = Intent(Intent.ACTION_DIAL)
    intent.data = Uri.parse("tel:0123456789")
    startActivity(intent)

Answer 3

I think you are looking for something like this:

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0123456789"));
startActivity(intent); 

This opens the dialer (or creates a chooser dialog if there are multiple apps installed which can place a phone call) with the number filled in, but does not actually start the call. See this answer for more info.
