How to make a phone call programmatically?

I'm passing to an activity the number to call by a bundle

and then, in such activity, I have a button to call to that number, this is the code:

callButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(bundle.getString("mobilePhone")));
            }
        }); 

Something is wrong, because when I press the button nothing happens...

What am I doing wrong?

PD: I'm using Android 1.5 compatible project... maybe phone call is incompatible to 1.5?

You forgot to call startActivity. It should look like this:

Intent intent = new Intent(Intent.ACTION_CALL);
			
intent.setData(Uri.parse("tel:" + bundle.getString("mobilePhone")));
context.startActivity(intent);

An intent by itself is simply an object that describes something. It doesn't do anything.

Don't forget to add the relevant permission to your manifest:

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

Tried this on my phone and it works perfectly.

Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:900..." ));
startActivity(intent);

Add this permission in manifest file.

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

 Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"+198+","+1+","+1)); 
			 startActivity(callIntent);

for multiple ordered call

This is used to DTMF calling systems. If call is drop then, you should pass more " , " between numbers.

Take a look there : http://developer.android.com/guide/topics/intents/intents-filters.html

DO you have update your manifest file in order to give call rights ?

This doesn't require a permission.

val intent = Intent(Intent.ACTION_DIAL, Uri.parse("tel:+123456"))
startActivity(intent)

Or

val intent = Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", "+123456", null))
startActivity(intent)

But it shows one more dialog (asking whether you want to call phone just once or always). So it would be better to use ACTION_CALL with a permission (see https://stackoverflow.com/questions/33473436/revoked-permission-android-permission-call-phone).

Here I will show you that how you can make a phone call from your activity. To make a call you have to put down this code in your app.

try {
    Intent my_callIntent = new Intent(Intent.ACTION_CALL);
    my_callIntent.setData(Uri.parse("tel:"+phn_no));
    //here the word 'tel' is important for making a call...
    startActivity(my_callIntent);
} catch (ActivityNotFoundException e) {
    Toast.makeText(getApplicationContext(), "Error in your phone call"+e.getMessage(), Toast.LENGTH_LONG).show();
}

It is working very well. In this way, you do not need to have permission from user. You can open directly phone calling part. > Trick point, use ACTION_DIAL instead of ACTION_CALL.

private void callPhoneNumber() {
    String phone = "03131693169";
    Intent callIntent = new Intent(Intent.ACTION_DIAL);
    callIntent.setData(Uri.parse("tel:" + phone));
    startActivity(callIntent);
}

protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main); 
   final Button button = (Button) findViewById(R.id.btn_call);
	button.setOnClickListener(new View.OnClickListener() {
		public void onClick(View v) {
			String mobileNo = "123456789";
			String uri = "tel:" + mobileNo.trim();
			Intent intent = new Intent(Intent.ACTION_CALL);
			intent.setData(Uri.parse(uri));
			startActivity(intent);
		}
	});*
 }

If anyone is looking for in Kotlin

    val  uri = "tel:+800******"
    val call_customer_service = Intent(Intent.ACTION_CALL)
    call_customer_service.setData(Uri.parse(uri))
    startActivity(call_customer_service)

Like some other solutions it requires android.permission.CALL_PHONE permission.

If you end up with a SecurityException (and the call does not work), You should consider requesting the user permission to make a call as this is considered a dangerous permission:

ActivityCompat.requestPermissions(
    activity,
    new String[] {Manifest.permission.CALL_PHONE},
    1
);

Note this has nothing to do with the manifest permission (that you must have as well)
