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;     }      }
