How can i make my game 100% fullscreen on android? This is where the status bar and the navigation bar are hidden, i think its called immersive layout.

Hi,

Good question, that’s an advanced topic: In order to use immersive mode you have to subclass the default Android activity and add some flags:

• Create a new activity in your andrdoid/src folder subclassing QtActivity (or VPlayActivity if you’re using Felgo plugins)
• Set the new activity as “android:name” in your AndroidManifest.xml’s activity declaration
• Override the onCreate and / or onWindowFocusChanged methods in your custom activity and add the flags as described here: https://developer.android.com/training/system-ui/immersive.html (or here for advanced usage: http://vitiy.info/small-guide-how-to-support-immersive-mode-under-android-4-4/). Make sure to call the super methods for all overridden methods.

Let us know if that worked for you!

Best,
Alex

Hi,  this is interesting but does this support vplay games, how will i use the new activity in my game?

Absolutely, I already tried a demo with it, it’s running fine when you’re following the steps below. 😉 If you need further help just let us know.

We probably add this directly into Felgo with one of the following updates.

Cheers,

Hi i managed to apply android  immersive layout to my game but there is black space at the top and bottom, it seems the Gamewindow is not going fullscreen of the phone. Alex can you help me on this part.

no wait but the game over screen is fully full screen so it must be an issue with my layout settings. i will look into this myself, thanks.

 

here is a snippet to use to add immersive layout in your app or game.

 

1. look for QtActivity.java

for example under C:\Qt\Qt5.2.0_android\5.2.0-rc1\android_armv7\src\android\java\src\org\qtproject\qt5\android\bindings\QtActivity.java

2. copy this line of code.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
  if (hasFocus) {
    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);
  }
}

3. look for the onWindowFocusChanged method in the QtActivity.java

4. Paste the above code in the method, example

@Override
public void onWindowFocusChanged(boolean hasFocus) {
  if (!QtApplication.invokeDelegate(hasFocus).invoked)
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
      if (hasFocus) {
      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);
    }
  }
  super.onWindowFocusChanged(hasFocus);
}

5. Save the file and run your game on devices Kitkat and above.

I upvote this feature for v-play.

Thanks

Thanks for sharing (I re-styled the snippet a little bit)!

Just a short note: If you edit the mentioned QtActivity.java it will apply to all new projects. The better approach therefore might be to create an own activity class like described in my first post.

Cheers,

Alex
