 Step 1:-First you can enabled youtube API YouYube Android Player API  provide by google.

 Please follow some Step and obtain google Developer API Key.

 1. you can download API client library an JavaDocs.

2.Go to Google developer Console and create New Project and registering your application .

 3.On the left-sidebar, select Dashboard and Enable API.

 4.On the left-sidebar, select Library and select YouTube Data Api. then you check api enable or not.

 5.On the left-sidebar, select Credential and Create new Key under public acess.





select Create Credential button then select RESTRIC KEY.

Open new settings..

select Android App Radio button and save. then generate API KEY and used this key in your android application..


6. Then you can add YouTubeAndroidApi.jar file in lib folder and compile in android studio and you can check in Gradle dependency add or not.

 
dependencies {
   .........


.......


......
    compile files('libs/YouTubeAndroidPlayerApi.jar')
}










7. Add Internet permission in manifest.xml file .

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



8. you can create Config  java class.
............................................................................................................ 
public class Config {
    public static final String _KEY= "AIzaSyDD5REJaO1Qu2y56v6QUW1FuGbnyariPI8";
    public static final String YOUTUBE_VIDEO_CODE = "CUciBrtqFGM";
}





............................................................................................................







9.you can create activity_main.xml

............................................................................................................


<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" >


    


<LinearLayout        


android:layout_width="fill_parent"        


android:layout_height="wrap_content"        


android:layout_centerInParent="true"        


android:layout_marginLeft="30dp"        


android:layout_marginRight="30dp"        


android:orientation="vertical" >

        


<LinearLayout            


android:layout_width="fill_parent"            


android:layout_height="wrap_content"            


android:gravity="center_horizontal"            


android:orientation="vertical" >

            


<com.google.android.youtube.player.YouTubePlayerView                


android:id="@+id/youtube_view"               


 android:layout_width="match_parent"                


android:layout_height="wrap_content"                


android:layout_marginBottom="30dp" >

            


</com.google.android.youtube.player.YouTubePlayerView>

        


</LinearLayout>


    


</LinearLayout>

</RelativeLayout>

............................................................................................................



10. MainActivity.java

............................................................................................................




public class MainActivity extends YouTubeBaseActivity implements        YouTubePlayer.OnInitializedListener {

    private static final int RECOVERY_DIALOG_REQUEST = 1;
    private YouTubePlayerView youTubeView;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);

        youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
        youTubeView.initialize(Config._KEY, this);

    }

    @Override    public void onInitializationFailure(YouTubePlayer.Provider provider,
                                        YouTubeInitializationResult errorReason) {
        if (errorReason.isUserRecoverableError()) {
            errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
        } else {
            String errorMessage = String.format("some error...", errorReason.toString());
            Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
        }
    }

    @Override    public void onInitializationSuccess(YouTubePlayer.Provider provider,
                                        YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {
            player.loadVideo(Config.YOUTUBE_VIDEO_CODE);
            player.setPlayerStyle(PlayerStyle.CHROMELESS);
        }
    }

    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_DIALOG_REQUEST) {
            getYouTubePlayerProvider().initialize(Config.DEVELOPER_KEY, this);
        }
    }

    private YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerView) findViewById(R.id.youtube_view);
    }

}

What is a XSream ?



XSream :-  XStream is a Simple Java Based Library to Serialize Java Object to XML. XStream is a light weight, fastest and provide Default Maping for most the object to serialize.



 XStream serializes used some internal fields e.g- private ,final, non-public and inner class. XStream Provide Security issues etc.



Example- Show xml formate.



<com.project.example.makexmlapp.Person>

                                                                   

<Name>Android Beginner point</Name>

Explain:-How to get Internal and External Memory Size Programmatically in Android Device ?



explain step by step....



1. you can check  internal & external memory is exist or not .






public static boolean externalMemoryAvailable() {
    return android.os.Environment.
            getExternalStorageState().equals(
            android.os.Environment.MEDIA_MOUNTED);
}





2. get Internal memory .






 public static String getTotalInternalMemorySize() {


    File path = Environment.getDataDirectory();
    StatFs stat = new StatFs(path.getPath());
    long BlockSize = stat.getBlockSize();
    long TotalBlocks = stat.getBlockCount();
    return formatSize(TotalBlocks * BlockSize);
}





3.get External memory .




public static String getTotalExternalMemorySize() {
    if (externalMemoryAvailable()) {
        File path = Environment.
                getExternalStorageDirectory();
        StatFs stat = new StatFs(path.getPath());
        long BlockSize = stat.getBlockSize();
        long TotalBlocks = stat.getBlockCount();
        return formatSize(TotalBlocks * BlockSize);
    } else {
        return ERROR;
    }
}





4. Convert Memory  size MB & KB Format.




 public static String formatSize(long size) {
        String suffixSize = null;

        if (size >= 1024) {
            suffixSize = "KB";
            size /= 1024;
            if (size >= 1024) {
                suffixSize = "MB";
                size /= 1024;
            }
        }

        StringBuilder BufferSize = new StringBuilder(
                Long.toString(size));

        int commaOffset = BufferSize.length() - 3;
        while (commaOffset > 0) {
            BufferSize.insert(commaOffset, ',');
            commaOffset -= 3;
        }

        if (suffixSize != null) BufferSize.append(suffixSize);
        return BufferSize.toString();
    }
}

Explain:-How to Convert Memory size in MB & KB  Format ?





In this tutorial implement conversion size in MB & KB format parameter type String method, below code . and explain how to Pass External And Internal Memory size  in this method..





// get Internal memory size...




public static String getTotalInternalMemorySize() {
    File path = Environment.getDataDirectory();
    StatFs stat = new StatFs(path.getPath());
    long blockSize = stat.getBlockSize();
    long totalBlocks = stat.getBlockCount();
    return formatSize(totalBlocks * blockSize);// pass memory size in this method
}






























// format Convert Method.......


public static String formatSize(long size) {
    String suffixSize = null;

    if (size >= 1024) {
        suffixSize = "KB";
        size /= 1024;
        if (size >= 1024) {
            suffixSize = "MB";
            size /= 1024;
        }
    }

    StringBuilder BufferSize = new StringBuilder(
            Long.toString(size));

    int commaOffset = BufferSize.length() - 3;
    while (commaOffset > 0) {
        BufferSize.insert(commaOffset, ',');
        commaOffset -= 3;
    }

    if (suffixSize != null) BufferSize.append(suffixSize);
    return BufferSize.toString();
