Enter android immersive mode - android

I need to enter android immersive mode in my react-native app, but when I try View.SYSTEM_UI_FLAG_IMMERSIVE) I got a lot of errors during compilation. I don't know anything about native android development and do it blindfold. So can you please briefly explain what and where I need to past to make it work.

I need only to automatically hide android navigation buttons on app start so it's enough to add few lines of code in MainActivity.java:
#Override
protected void onStart()
{
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // прячем панель навигации
| View.SYSTEM_UI_FLAG_FULLSCREEN // прячем строку состояния
| View.SYSTEM_UI_FLAG_IMMERSIVE);
super.onStart();
}

what about adding android:theme="#android:style/Theme.NoTitleBar.Fullscreen" in your android manifest xml file??

How to ask permission or automatically set the phone's full screen on settings - android studio

I am trying to set my activity to full screen using this code below:
private void hideSystemUI() {
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN);
}
But I am getting a black color navigation bar on certain phones because of the condition on settings -> display where certain phones need to permit apps to use a fullscreen mode. To address this issue I decided that I need to implement a permission checker when the activity inflates. If there is another way please tell me and I will try to implement it.
Edit:
Here is the link of the conditions for phones that I am talking about:
https://www.gottabemobile.com/how-to-enable-full-screen-apps-on-galaxy-s10/
this problem happen with me for 2 different devices and this because of the front camera notch or screen cutout.
I used this code in oncreate() :
hideSystemUI();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
getWindow().getAttributes().layoutInDisplayCutoutMode =
WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES; }
Or in the theme style xml file add this line :
<item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
In your manifest file put
android:theme="#style/Theme.Design.NoActionBar"
or
android:theme="#style/AppTheme"
and in your activity call hideSystemUI(); before setting the content view
like this :
final int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
getWindow().getDecorView().setSystemUiVisibility(flags);
setContentView(R.layout.activity_main);

How to hide the navigation bar in Android 6.0?

I have the following code:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
This code worked fine for Android Lollipop, hiding the navigation bar in sticky immersive mode. But now, when I test it on my phone with Android 6.0, the navigation bar goes away while a black rectangle where the navigation bar used to be remains, blocking a portion of the screen.
Looking back on my question, I'd like to add the solution I'm using now which hasn't failed me since, I don't remember if I saw it somewhere else or came to it myself but I'm glad it works.
public static void activiateFullscreen(Activity activity){
View decorView = activity.getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
if (Build.VERSION.SDK_INT >= 17) {
uiOptions ^= View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_FULLSCREEN
|View.SYSTEM_UI_FLAG_LOW_PROFILE;
}
if (Build.VERSION.SDK_INT >= 19) {
uiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
}
decorView.setSystemUiVisibility(uiOptions);
}
Hope this helps someone!
I've discovered a workaround that seems to resolve this issue. I support portrait and landscape, and noticed that the black rectangle went away if I rotated into landscape or started the app in landscape. Adding the following code to my main activity's onCreate() method (after setting the immersive flags) resolved the issue:
if (Build.VERSION.SDK_INT >= 23) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
}

How to Hide ActionBar and NavigationBar completely

I knew this question is being asked previously but not getting the accurate solution.
I want to hide ActionBar and NavigationBar from my activity in or order to make it full screen. I tried the below code in my Activities OnCreate Method but its showing Action Bar for some fraction of seconds and than making it full screen. In Galaxy S3 (android 4.3), its even more than a second. so how can I make it completely invisible and my activity as full screen completely from the beginning only.
I saw many apps running on S3 only, but their is no ActionBar, not even for fraction seconds.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
if (Build.VERSION.SDK_INT < 19) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
In the onCreate function of your activity add this code before setContentView:
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
In AndroidManifest file write
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
If the minimum SDK Version of your application is 19 (KitKat), then you have to add an additional piece of code to your onResume function:
getWindow().getDecorView().setSystemUiVisibility
( View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY );
In AndroidManifest file write
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
in activity tag
and use
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
befor setContentView(R.layout.activity_main);
Try android:theme="#android:style/Theme.NoTitleBar.Fullscreen" in the declaration of your Activtiy in your Manifest.
try this before setContentView
//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
This Android Developer and This Post demonstrates Immersive Full-Screen Mode which allows your app to go full screen.
tltr;
try this snippet which I got from the Android Developer website:
View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
Hopefully I helped!
i think you have to write just
getActionBar().hide(); (Above Api level 11)
or
getSupportActionBar().hide();(Up to Api level 8)
thats it...

Can you detect whether an application is in immersive mode in Fragment.onCreateView?

In a fragment I have implemented a GestureDetector.SimpleOnGestureListener so that I can enter/exit immersive mode when onSingleTapUp is detected.
A FragmentStatePagerAdapter is used to move between these fragments on swipe left/right. If you enter immersive mode then swipe to a new fragment the UI remains in immersive mode.
However, in the onCreateView method of the new fragment I need to detect whether the UI is in immersive mode to when creating my listener.
I have tried calling getSystemUiVisibility() on the new view but this returns SYSTEM_UI_FLAG_VISIBLE.
Is there a method for detecting whether the application is in immersive mode from any view or fragment regardless of whether that initiated the transition to immersive mode?
If anyone is looking for a more in-depth answer. To check if the window is in immersive vs non-immersive you can do something use:
(getWindow().getDecorView().getSystemUiVisibility() & View.SYSTEM_UI_FLAG_IMMERSIVE) == View.SYSTEM_UI_FLAG_IMMERSIVE
An example of it's usage for swapping between immersive and normal:
private void toggleImmersive() {
if ((getWindow().getDecorView().getSystemUiVisibility() & View.SYSTEM_UI_FLAG_IMMERSIVE) == View.SYSTEM_UI_FLAG_IMMERSIVE) {
getWindow().getDecorView().setSystemUiVisibility( // Go fullscreen
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
} else {
getWindow().getDecorView().setSystemUiVisibility( // Go immersive
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE);
}
}
#Mark, it sounds like you may have gotten it resolved based on my previous comment: use a View owned by the Activity to call getSystemUiVisibility() rather than the Fragment.

Android 4.4 full-screen mode for Progress Dialog

I want my app to run in full-screen mode on devices running Android 4.4.
I have set View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION for my view and it runs in full-screen.
The problem is when I show a ProgressDialog. Then the app exits full-screen mode and the navigation buttons at the bottom are visible agin.
Is it possible for an app to remain in full-screen mode when a progress dialog is shown?
There's a little workaround I found on this topic: How to maintain the Immersive Mode in Dialogs? thanks to Beaver6813's answer (here is the sample code project on GitHub).
So basically, what I did to use this solution on my ProgressDialog is:
Add two variables to my MainActivity class:
private ProgressDialog pDialog;
private Activity context;
Add the following code in my onCreate method:
context = this;
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE);
Add the following code where I start my ProgressDialog method:
pDialog = new ProgressDialog(context);
pDialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
pDialog.show();
pDialog.getWindow().getDecorView().setSystemUiVisibility(
context.getWindow().getDecorView().getSystemUiVisibility());
pDialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
That should do the trick!
