How to make a phone call in android

We are able to make a phone call in android via intent. You need to write only three lines of code to make a phone call.

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+8802177690));//change the number
startActivity(callIntent);

Example of phone call in android

activity_main.xml

Drag the EditText and Button from the pallete, now the activity_main.xml file will like this:

File: activity_main.xml

<RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="118dp"
        android:text="Call" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="25dp"
        android:ems="10" />

</RelativeLayout>

Write the permission code in Android-Manifest.xml file

You need to write CALL_PHONE permission as given below:

File: Android-Manifest.xml

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:androclass="http://schemas.android.com/apk/res/android"
    package="com.example.phonecall"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

    <uses-permission android:name="android.permission.CALL_PHONE" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.phonecall.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Activity class

Let's write the code to make the phone call via intent.

File: MainActivity.java

package com.example.phonecall;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {
	EditText edittext1;
	Button button1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Getting the edittext and button instance
        edittext1=(EditText)findViewById(R.id.editText1);
        button1=(Button)findViewById(R.id.button1);

        //Performing action on button click
        button1.setOnClickListener(new OnClickListener(){

			@Override
			public void onClick(View arg0) {
				String number=edittext1.getText().toString();
				Intent callIntent = new Intent(Intent.ACTION_CALL);
				callIntent.setData(Uri.parse("tel:"+number));
				startActivity(callIntent);
			}
        	
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
    
}
