Create a new activity

private void call(String num) {
    try {
        Intent callIntent = new Intent(Intent.ACTION_CALL);
       num="tel:"+num;
        callIntent.setData(Uri.parse(num));
        startActivity(callIntent);
    } catch (ActivityNotFoundException e) {
        Log.e("helloandroid dialing example", "Call failed", e);
    }
}

What happens when you begin a telephone call depends, partially, on the phone system. The number may be inaccurate. The system may be occupied or generally inaccessible. The call could be interfered. Here, on the other hand, you see no failure taking care of rationale, aside from discovering and logging special cases that might be tossed if slip experiences an issue when discovering applications that can prepare Intent articles.
