Android Call function programmatically

1.Create a Class Call_Utils

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;

public class Call_Utils {

    /**
     * @param str_phno
     * @param activity
     * Function for calling a contact.
     */
    public static void Call_contact(String str_phno,Activity activity){
        Intent intent = new Intent(Intent.ACTION_CALL);
        intent.setData(Uri.parse("tel:"
                + str_phno.trim()));
        activity.startActivity(intent);
    }
   
}

2.Use this in your MainActivity



import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Call_Utils.Call_contact("09123456789", MainActivity.this);
    }
}

3.Add permission in manifest file

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />
 <!-- Call Phone Permissions -->
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

Now,you can use call function programmatically.
