If you have a video in firebase database and you want to play it in a VideoView in Sketchware, follow the steps given below.

1. Create a new Activity PlayVideoActivity.

2. In View settings remove status bar and toolbar, and set screen orientation to both portrait and landscape.

3. Create a String variable url.

4. In onCreate, set url to the video url

5. In onCreate event:
// Define a FrameLayout.
FrameLayout layout = new FrameLayout(this);

FrameLayout.LayoutParams layoutparams=new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, Gravity.CENTER_HORIZONTAL|Gravity.CENTER_VERTICAL);
layout.setLayoutParams(layoutparams);

// Define VideoView and MediaController.
final VideoView vidview = new VideoView(this);
FrameLayout.LayoutParams vvlp = 
new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
vidview.setLayoutParams(vvlp);

final MediaController mediaControls = new MediaController(this); mediaControls.setAnchorView(vidview); vidview.setMediaController(mediaControls);

// Define a ProgressBar.
final ProgressBar mBufferingBar = new ProgressBar(this);

RelativeLayout.LayoutParams pblp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

pblp.addRule(RelativeLayout.CENTER_VERTICAL);

mBufferingBar.setLayoutParams(pblp);

// Define a RelativeLayout.
RelativeLayout rl = new RelativeLayout(this);

RelativeLayout.LayoutParams lparams = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
rl.setLayoutParams(lparams);

// Add VideoView to FrameLayout.
layout.addView(vidview);

// Add FrameLayout and ProgressBar to RelativeLayout.
rl.addView(layout);
rl.addView(mBufferingBar);

// Set RelativeLayout as view of the Activity.
setContentView(rl);

// Set the url as the Uri of VideoView.
vidview.setVideoURI(Uri.parse(url));

// Start Video and make ProgressBar GONE when video is prepared.
vidview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mBufferingBar.setVisibility(View.GONE);
vidview.seekTo(1);
vidview.start();
}
});

6. Save and run the project.


To pause the video and to play it from saved position in beginning:
* Create a more block extra. Here declare the VideoView, an int mCurrentPosition, and define event onSaveInstanceState.
}
VideoView vidview;
private int mCurrentPosition = 0;

@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// Save current position of VideoView in Bundle outState of onSaveInstanceState, with key "play_time".
outState.putInt("play_time", vidview.getCurrentPosition());
}
{

* In onCreate use codes as above with following changes:
//replace
final VideoView vidview = new VideoView(this);
with
vidview = new VideoView(this);
// Add following code to set current position
if (savedInstanceState != null){
mCurrentPosition = savedInstanceState.getInt("play_time");
}
// Change onPreparedListener code to
vidview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mBufferingBar.setVisibility(View.GONE);
if (mCurrentPosition > 0){
vidview.seekTo(mCurrentPosition);
} else {
vidview.seekTo(1);
}
vidview.start();
}
});

* In onPause event, pause the VideoView.
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N){
vidview.pause();
}

* In onStop event, stop the VideoView
vidview.stopPlayback();
