How can I call a number from button press in Android?

Question

I'm very much a beginner at this and I'm struggling to get this to work.

When button is pressed, I simply want the dialer to open with the specified number automatically inputted.

So far I've tried the following:

Button btn_call_us = (Button) findViewById(R.id.btn_call_us);
       btn_call_us.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:00000000"));
                startActivity(callIntent);

            }
        });

I've also tried:

Button btn_call_us = (Button) findViewById(R.id.btn_call_us);
        btn_call_us.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                String phoneno="00000000";

                Intent i=new Intent(Intent.ACTION_CALL,Uri.parse(phoneno));
                startActivity(i);

            }
        });

I've added the permission ACTION_CALL to the manifest.

Whenever I click the Call button the app force closes.

Any assistance would be greatly appreciated.

Thank you!

You should definitly learn how to read your logcat, it's much more important to you than just getting the answer to this question. — Snicolas, May 07 '13 at 06:28
As above, still very new to all this. I will get the logcat setup. I know I definitely have a lot to learn but thanks for pointing this out. — R-Dub, May 07 '13 at 08:41

String number = "12345678";
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" +number));
    startActivity(intent);

You need to add this Permission to your manifest.

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

Wow! First time using SO and really wasn't expecting such a quick response. Thank you very much. This worked perfectly. I made one change and that was ACTION_CALL to ACTION_DIAL so it gives the user the option to back out or confirm the call. – R-Dub May 07 '13 at 06:36
@Nucleotide I'm glad I could help. Anytime :) – Naskov May 07 '13 at 06:38

If you want the dialer to open with the number use ACTION_DIAL

Intent i=new Intent(Intent.ACTION_DIAL,Uri.parse("tel:" + phoneno));

You do not need any permission

Make sure you have added the

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

tag at a correct level in the AndroidManifest.xml file (outside the <application ... /> tag but within the <manifest ... /> tag):

Try this.

startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneno)));

Also, add the permission android.permission.CALL_PHONE in your manifest file.

Add the following in the manifest file and it should work fine -

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