The High Five: new discoveries in space and fashion

What did Saturn say to NASA this week? “High Five.” Here’s a look at a few of the top trending Google searches orbiting the week of April 24.

What have you done this week?

For the first time ever, a spacecraft cruised through the narrow gap between Saturn and its rings. Now NASA’s Cassini is beaming information back to the mothership, and telling NASA about all the cool stuff it saw. Science, FTW! After the feat, people searched on Google for more information: “How does Cassini communicate with Earth?” and “How long did it take for Cassini to reach Saturn?” Some were looking for a refresher astronomy course, asking “How far is Saturn from Earth?” and “How many rings does Saturn have?”

Here comes the tour

Maybe we’re amazed that Paul McCartney is still touring—that guy is Here, There and Everywhere! It’ll be a Hard Day’s Night on the road, but fans twisted and shouted when he announced his 2017 tour dates this week. Though you can’t buy his love, you can buy a ticket to his show. And fans are itching to get those tickets, with questions like “How much are Paul McCartney tickets?” and “When do tickets for Paul McCartney go on sale?” Let it Be soon.

Centi-versary

This Saturday marks President Trump’s 100th day in office, and the first few months of his administration have prompted people to learn more about political concepts and processes. The five most-searched terms related to politics during Trump’s first 100 days are “recuse,” “filibuster,” “vetting,” “executive order” and “immigrant.” Another fun fact to bring to your political debates this weekend: the most-searched names alongside the phrase “Trump handshake”: Justin Trudeau, Angela Merkel, Neil Gorsuch, Shinzo Abe and Benjamin Netanyahu.

Clear as mud

Remember when you were a kid and tracking mud in the house got you into trouble? Times have changed—go ahead and get mud all over yourself. Or pay $425 for jeans covered in fake mud. Perplexed (yet intrigued) shoppers have been searching, “What are mud jeans?” and “Where can I buy mud jeans?”

Shifting gears

NASCAR legend Dale Earnhardt Jr., is at the finish line—he announced he will retire after the 2017 season. Fans are curious about when and why he is retiring and “Who will replace Dale Earnhardt Jr.?” Though he’s known nationwide, southern regions in the U.S. searched most for Earnhardt this week. Top states included North Carolina, West Virginia, Tennessee, Alabama and South Carolina.

Secure Multimedia Playback on Android with BlackBerry Dynamics

BlackBerry Dynamics allows you to secure data in transit using its secure connectivity.  It also provides solutions to secure your data secure while at rest using its secure file system and secure database.  But what about keeping your data secure while it’s in use?

In many scenarios, securing data in use isn’t much of a concern because that data is only briefly stored in RAM only available to your application. But what about large pieces of data, such as audio or video files that are read from flash memory?  If you were to attempt to use a URI in the Android MediaPlayer that points to a video file stored in the BlackBerry Dynamics file system, it will fail to play because the Android MediaPlayer is unable to understand the encrypted file.  Some developers have attempted to work around this issue by copying a media file outside of the BlackBerry Dynamics secure file system for playback, and then delete it when playback is complete.   While this does allow for playback of the file, it does not keep your media files secure.  While that temporary but unencrypted file exists on the regular file system, other applications could gain access to it.

The way to solve this problem, and keep your media files secure is to implement a solution that allows playback directly from the BlackBerry Dynamics secure file system. I’m going to show you a couple of ways this can be done.  One solution will involve creating a custom MediaDataSource that can read from the BlackBerry Dynamics secure file system and provide the Android MediaPlayer with the data it needs for playback.  The second will take a similar approach, but make use of the popular open source media player called ExoPlayer.

Choosing Between Android Media Player and ExoPlayer

If you are creating a new application targeting current versions of Android, the solution that uses MediaPlayer  and MediaDataSource is likely the approach to take.  MediaDataSource was added in API level 23, so it is a relatively new API.  If you need to support older versions of Android, refer to the solution below that uses ExoPlayer, which supports API level 16.  There are some additional elements to consider, which are well described in the Pros and Cons section of the ExoPlayer documentation.

Using Android Media Player

A complete working sample project that uses this solution is available on the BlackBerry Github site here: BDVideoPlayBack

The first step is to extend MediaDataSource and ensure we are using the BlackBerry Dynamics file system APIs.

import com.good.gd.file.File;
import com.good.gd.file.RandomAccessFile;


public class BDMediaDataSource extends MediaDataSource
{
    private RandomAccessFile randFile;
    private long size;
…

Next we create a constructor that accepts a String that contains the path and filename to the encrypted file. In this method, we open the file using the BlackBerry Dynamics file APIs.

public BDMediaDataSource(String fileName) throws IOException
{
    File file = new File(fileName);
    size = file.length();
    randFile = new RandomAccessFile(file, "r");
}

Next there are three methods of MediaDataSource that need to be overridden. The readAt method is used by the MediaPlayer to request a specific portion of the file.  Again, we use the BlackBerry Dynamics file APIs to read and return the requested portion of the file.

@Override
public int readAt(long position, byte[] buffer, int offset, int length) throws IOException
{

    if (randFile != null)
    {
        randFile.seek(position);

        return randFile.read(buffer, offset, length);
    }
    else
    {
        return -1;
    }
}

The next two methods are getSize and close. getSize returns the size of the file.  Note that this is the size of the unencrypted file, which is what is returned by the BlackBerry Dynamics file APIs.  The final method is close, which is called when the file should be closed.

@Override
public long getSize() throws IOException
{
    return size;
}

@Override
public void close() throws IOException
{
    if (randFile != null)
    {
        randFile.close();
        randFile = null;
    }
}

BDMediaDataSource is now ready to be used with MediaPlayer. The following code snippet demonstrates how that can be done.

MediaPlayer mp = new MediaPlayer();
BDMediaDataSource source = new BDMediaDataSource("file.mp4");
mp.setDataSource(source);
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        mp.start();
    }
});
mp.prepareAsync();

Using ExoPlayer

A complete working sample project that uses this solution is available on the BlackBerry Github site here: ExoPlayerVideoPlayBack

The solution that uses ExoPlayer has a very similar design to what was done using Android Player above. For ExoPlayer, we extend DataSource, which is used to provide data that will be played back and use the BlackBerry Dynamics file system APIs to read the securely stored media files.  An empty constructor is also defined.

import com.good.gd.file.GDFileSystem;
import com.good.gd.file.FileInputStream;

public final class BDDataSource implements DataSource
{

    private FileInputStream inputStream;
    private boolean fileOpen;
    private Uri filePath;
    private long bytesRemaining = 0;

public BDDataSource() {}

Next we override the open method, which passes in the file to be opened. In this method, we initialize FileInputStream that will be used to read the data.

@Override
public long open(DataSpec dataSpec) throws IOException
{
    filePath = dataSpec.uri;
    //Trim "file:///" that's prefixed to the start of the URI.
    inputStream = GDFileSystem.openFileInput(filePath.toString().substring(8));

    if ( inputStream != null )
    {
        fileOpen = true;
        bytesRemaining =  inputStream.available();
    }

    return bytesRemaining;
}

The next method to override is the read method, where we use the FileInputStream initialized in the open method to read the file at the desired position.

@Override
public int read(byte[] buffer, int offset, int readLength) throws IOException {
    if (bytesRemaining == 0)
    {
        return -1;
    }
    else
    {
        int bytesRead = 0;
        bytesRead = inputStream.read(buffer, offset, readLength);

        if (bytesRead > 0) {
            bytesRemaining -= bytesRead;
        }

        return bytesRead;
    }
}

The getUri method is also overridden and returns the path to the file in the BlackBerry Dynamics file system.

@Override
public Uri getUri() {
    return filePath;
}

The final method overridden is the close method, that closes the FileInputStream and underlying file when playback ends.

@Override
public void close() throws IOException {
    filePath = null;
    if (inputStream != null)
    {
        try
        {
            inputStream.close();
        }
        catch (IOException e)
        {
            throw new IOException(e);
        }
        finally
        {
            inputStream = null;
            if (fileOpen)
            {
                fileOpen = false;
            }
        }
    }
}

The code sample below shows how BDDataSource could be used as a DataSource by ExoPlayer.

SimpleExoPlayer player;

// 1. Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory =
        new AdaptiveVideoTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector =
        new DefaultTrackSelector(videoTrackSelectionFactory);

// 2. Create a default LoadControl
LoadControl loadControl = new DefaultLoadControl();

// 3. Create the player
player = ExoPlayerFactory.newSimpleInstance(v.getContext(), trackSelector, loadControl);

// Bind the player to the view.
simpleExoPlayerView.setPlayer(player);

// Produces DataSource instances through which media data is loaded.
DataSource.Factory dataSourceFactory = new BDDataSourceFactory();

// Produces Extractor instances for parsing the media data.
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();

// This is the MediaSource representing the media to be played.
Uri uri = Uri.fromFile(new File("file.mp4"));

MediaSource videoSource = new ExtractorMediaSource(uri,
        dataSourceFactory, extractorsFactory, null, null);

// Prepare the player with the source.
player.prepare(videoSource);

Wrapping Up

Both samples provide similar solutions that you can use from Android API level 16 through to current versions of Android. Give them a try and make sure your data is secure when in transit, at rest and in use.

Our ongoing commitment to support computer science educators

Meet Daryl Detrick, a computer science (CS) teacher at Warren Hills High School in Washington, NJ. He’ll tell you that he doesn’t just teach “coding”—he helps students understand how to approach complex problems that will improve the world around them. He started teaching computer science in 2008, at a time where there were very few resources available to help support him.

“The biggest thing I bring into the classroom is inspiration.” – Daryl Detrick

Many CS teachers lack the resources to become skilled and confident in their roles. So today we’re announcing new support for teachers like Mr. Detrick, starting with an additional $2 million in grants to support nonprofit organizations that provide support for teachers throughout their educational careers. Our goal to help increase access to CS skills by empowering more skilled and confident CS teachers globally.

Supporting existing CS teachers and inspiring new ones

Mr. Detrick’s first CS professional development experience was through CS4HS, a Google program that funds educators with localized computer science professional development. Through these grants in 2017-2018, 79 organizations in Australia, U.S., Canada, China, Europe, the Middle East and Africa will receive funding to create pathways and content to foster local communities of educators.

CS4HS focuses on teachers to increase the availability of quality computer science education, while many of Google’s other CS education programs, like Made with Code, focus on students. Over the past 10 years, CS4HS has contributed $10 million to professional development (PD) providers around the world to help train and empower teachers—like Western Wyoming Community College, which helped rural teachers integrate gaming into their CS classes, or Australian Catholic University, which trained 1,600 pre-service teachers in accordance with Australia’s national technology curriculum, among others.

Given the shortage of qualified teachers, it’s important not only to help the educators currently in the field, but also to inspire more teachers to join them. That’s why we’re also supporting pre-service teacher preparation programs developing new coursework that trains aspiring educators at the College of St. Scholastica, the University of California at Irvine, the University of Texas at Austin, and Huston-Tillotson University. We’re excited to work with these universities to help them share their resources with other higher education programs, equipping the next generation of educators with the knowledge and skills to teach CS and computational thinking (CT).

Although we’ve seen a small increase of computer science teachers in recent years—6 percent since 2008—the subject is still largely regarded as an extracurricular activity, and one of the key barriers is a lack of qualified teachers. But research suggests that building training and local pathways are two key ways to retain and grow excellent educators. Today’s grants will help universities and nonprofits reach educators with PD opportunities that enhance their CS and technical skills development, improve their confidence in the classroom, and provide leadership training so that they can be advocates for CS education in their communities.

Growing the community of computer science educators

With the help of his principal and faculty partners at Carnegie Mellon, Rutgers and Kean University, Mr. Detrick has grown his school’s CS program from 53 students to more than 200. He’s also a lead educator advocate for the CSTA New Jersey chapter, and works with the CSNJ advocacy group to influence State legislation that would require all high schools to offer computer science.

We’re excited to support new and future CS educators around the world. Even though computer science is a relatively new discipline for most schools, the enthusiasm is growing—and educators like Mr. Detrick are helping to pave the way for students to learn skills they’ll need for the future. To explore more information about communities of CS teachers near you, explore our computer science education resources and partners.
