launch skype after click button in the app

[Sara Brown]

i need to have video call in my application and i am thinking of calling the skype application by using intent.

below is my code.

package com.example.skypeintent;

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

public class SkypeActivity extends Activity {

	Button btn1;
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_skype);		
		
		btn1 = (Button)findViewById(R.id.button1);
		btn1.setOnClickListener(new OnClickListener(){
			public void onClick(View v){
				Intent i = new Intent(Intent.ACTION_VIEW);
				i.setComponent(new ComponentName(
						"com.skype.android.lite",
						"com.skype.android.lite.SkypeActivity"
						));
				startActivity(i);
			}
		});
	
	
	}

	@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_skype, menu);
		return true;
	}

}

this is the code for androidManifest

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".SkypeActivity"
            android:label="@string/title_activity_skype" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

this is the code for the layout

<RelativeLayout xmlns:android="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=".SkypeActivity" >


    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:text="Button" />

</RelativeLayout>

for this layout, i only put a single button and when it click, it will launch skype application thus i can make video call.

i tried this code as given above and it wont even launch the skype. is there any mistakes i make? thank you for the help
