Videoview is not displaying in nougat 24 but displaying and working in android Q 29

Question

I'm working application. when button click happens, it displays popup window with videoview. It is showing in android 29 api, but not in android 24 api. the following is the code of showvideopopup function for it.

private void showVideoPopup()
    {
        LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View customView = layoutInflater.inflate(R.layout.dispensing_intro,null);

        int uiOptions =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;
        customView.setSystemUiVisibility(uiOptions);


//        closePopupBtn = (Button) customView.findViewById(R.id.closeView);

        //instantiate popup window
        dispense_intro_popup = new PopupWindow(customView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

        //display the popup window
        dispense_intro_popup.showAtLocation(dispense_intro_view, Gravity.CENTER, 0, 0);

        VideoView video = (VideoView) customView.findViewById(R.id.dispense_intro);
        Uri videoUri = Uri.parse("android.resource://" + getPackageName() + "/raw/"+ R.raw.dispense_intro);
        video.setVideoURI(videoUri);
        video.start();

        video.setOnCompletionListener(this);

    }

The Following is the popup.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:background="#b3000000"
    android:layout_height="700dp"
    android:id="@+id/dispense_intro_holder"
    android:layout_gravity="center"
    android:gravity="center">


    <VideoView
        android:id="@+id/dispense_intro"
        android:layout_gravity="center"
        android:layout_width="640dp"
        android:layout_height="360dp"  />
</LinearLayout>

Answer 1

Use DialogFragment() instead of PopupWindow.

Then add the following code to fragment onCreateView

PopupFragment.java

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.popup, container, false);
        setStyle(DialogFragment.STYLE_NO_TITLE, R.style.FullscreenTheme);
        VideoView video = (VideoView) rootView.findViewById(R.id.dispense_intro);
        Uri videoUri = Uri.parse("android.resource://" + getPackageName() + "/raw/"+ R.raw.dispense_intro);
        video.setVideoURI(videoUri);
        video.start();

        video.setOnCompletionListener(this);

        return rootView;

}

And to make dialog fragment to full screen use the following code for onDialogCreated

public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        dialog.getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_IMMERSIVE
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        // Hide the nav bar and status bar
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN);
        return dialog;
    }
