Question

I could only find “how to make a call from your application” and the solution is:

EditText et = (EditText) findViewById(R.id.editText);
String s = et.getText().toString();

try {
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:" + s));
    startActivity(callIntent);
    } catch (ActivityNotFoundException activityException) {
    Log.d("Calling a Phone Number", "Call failed" + activityException);
    }

But this directly makes a call, without confirming. Like if the number must be preceded with a 0 user must be allowed to do it and then make a call and once the call is finished he must be taken back to the application activity where he started the intent.

Answer 1

Simply change Intent.ACTION_CALL to Intent.ACTION_VIEW in your code.

Update:
To call just the phone use Intent.ACTION_DIAL, however Intent.ACTION_VIEW call messaging or phone.
