Call intent in Android

Question

How can I make call by pressing button? I get my number as a string from EditText. Here is my sample code:

String phone = editPhone.getText().toString();
btnPhone.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {

                call();
            }
        });
public void call() {
    try {
        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse(phone));
        startActivity(callIntent);
    } catch (ActivityNotFoundException activityException) {
         Log.e("myphone dialer", "Call failed", e);
    }
}

I added all permissions to manifest file.

but I am getting NullPointerexception

Milksop

what is your specific problem? – Halfhardy

my app crushes by null pointer exception. can you provide me sample source code to make phone calls?? – Milksop

Your code is fine, the null pointer is coming from what line? the "String phone" part? – Halfhardy

Answer 1

This simple approach should work for you.

Ex.

public class CallActivity extends Activity{
   String phone = "";

   onCreate()
   {
        btnPhone.setOnClickListener(new View.OnClickListener() { 
            @Override 
            public void onClick(View arg0) { 
                phone = editPhone.getText().toString(); 
                call(); 
            } 
        });    
   }

   public void call() {   
            Intent callIntent = new Intent(Intent.ACTION_CALL);          
            callIntent.setData(Uri.parse("tel:"+phone));          
            startActivity(callIntent);  
   }
}

You might be using String variable phone out of scope.

Answer 2

I think you missed the "tel:" part in the URI.

Replace the following..

Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse(phone));
        startActivity(callIntent);

with

Intent callIntent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+phone));
       startActivity(callIntent);

or

Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setData(Uri.parse("tel:"+phone));
            startActivity(callIntent);

Answer 3

see below code it may help you.

for call

EditText num = (EditText)findViewById(R.id.number_edit);
String uri = "tel:" + num.trim();
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(uri));
startActivity(intent);

for open dialer

Intent dial = new Intent();
dial.setAction("android.intent.action.DIAL");
dial.setData(Uri.parse("tel:"));
startActivity(dial);

call end worked in my app. see if i use above code then phone dialer open and there is red button for end call. check it again. – Asti

Answer 4

String PhoneNo="[phone]"
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + PhoneNo));
startActivity(intent);

and add a permission in manifest

<uses-permission android:name="android.permission.CALL_PHONE" />

Answer 5

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse(phone));
startActivity(callIntent);

above is the only method you use for calling a phone number in android, when you click on the call button a 'dilerpad' activty is started with perpopulated phone number, and the call will go if you press the call button on the dialer pad.

Dilley

you cant make call by directly clicking on the call button, in turn it should go to the dialer pad activity. – Dilley

Actually you can, with the permission to call. There are 2 Actions, ACTION_DIAL & ACTION_CALL : Where action dial takes you to the dialer with the number and call sends the call out. – Halfhardy

developer.android.com/reference/android/content/… Read that. – Halfhardy

@JoxTraex wait i wll check it out – Dilley

in what place i must insert this intent? – Milksop

Try this

String uri = "tel:" + num.trim();
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(uri));
