How to set full screen mode for activity in Android? I am using the following code to set full screen but it generates an error:

Exception:

android.util.AndroidRuntimeException: 
    requestFeature() must be called before adding content.         

Code:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,        
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 1

please check the code

public 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.main);
}

and note it is set before setting the content view

Answer 2

try this in AndroidManifest:

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

Answer 3

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                        WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 4

put requestWindowFeature first in your code....like this...

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
