Answer 1

you can do it in java file by

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);

or in AndroidManifest.xml

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

With transparent notification bar read this link.

Answer 2

There is a new feature called Immersive FullScreen mode where all the UI elements other than your Activity are hidden. One can get those those back by swiping down. Use the following code to achieve this :

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN|View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|View.SYSTEM_UI_FLAG_IMMERSIVE|View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
