Since Jellybean (4.1) there is a new method that doesn't rely on the WindowManager. Instead use setSystemUiVisibility off of the Window, this gives you more granular control over the system bars than using WindowManager flags. Here is a full example:

if (Build.VERSION.SDK_INT < 16) { //ye olde method
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else { // Jellybean and up, new hotness
    View decorView = getWindow().getDecorView();
    // Hide the status bar.
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    decorView.setSystemUiVisibility(uiOptions);
    // Remember that you should never show the action bar if the
    // status bar is hidden, so hide that too if necessary.
    ActionBar actionBar = getActionBar();
    if(actionBar != null) {
         actionBar.hide();
    }
}

Add this to your manifest file under the activity tag in which you want to hide status bar

android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 

and you are done :)

add these lines in oncreate() method

     requestWindowFeature(Window.FEATURE_NO_TITLE);// hide statusbar of Android
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);
