Android - Play MP4 video file from extension file
I followed all the steps when testing the extension file for my application. Where am I now stuck on how to play the video file contained in this extension file.
I was able to download it from Google Play and I can see it in the folder it should be in when I browse my file manager.
I've been looking for the past couple of days trying to figure out how to play the file. At the moment there is only one to maintain the appropriate size for testing.
I tried to parse the URI and set it in the video ad, however it always shows that the video cannot be played.
I also tried this code so far to access it (as read in the documentation and I replaced the parameters with my parameters):
// Get a ZipResourceFile representing a merger of both the main and patch files
ZipResourceFile expansionFile = APKExpansionSupport.getAPKExpansionZipFile(appContext,
mainVersion, patchVersion);
// Get an input stream for a known file inside the expansion file ZIPs
InputStream fileStream = expansionFile.getInputStream(pathToFileInsideZip);
What should I do with the input stream to play the video?

Custom video player
public static final Uri CONTENT_URI = Uri
.parse("content://your.package.name.Utility.EHZipUriProvider");
public static VideoView mview;
public static void playVideo(Context context, VideoView resource, String VIDEO_NAME) {
position = 0;
mview = resource;
Uri video = Uri.parse((CONTENT_URI + "/" + VIDEO_NAME));
mview.setVideoURI(video);
mview.start();
mview.setOnCompletionListener(new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mview = null;
}
});
}
Call in action
VideoPlayer.playVideo(context, vv, "rulesofenglish.mp4");

For example, my app package name is:
com.bluewindsolution.android.sampleapp
Then my extension file should be
main.1.com.bluewindsolution.android.sampleapp.obb
You can find details in here :
[Main | patch] & l .; extension-version>. <package-name> .obb
From an extension, you can get it in three ways:
via AssetFileDescriptor
// This one works with an image file and a media file.
// Get a ZipResourceFile representing a specific expansion file
// mainContext, version number of your main expansion, version number of your patch
ZipResourceFile expansionFile = APKExpansionSupport.getAPKExpansionZipFile(this, 1, 0);
AssetFileDescriptor afd_img1 = expansionFile.getAssetFileDescriptor("your_path/your_file.jpg");
AssetFileDescriptor afd_mpbg = expansionFile.getAssetFileDescriptor("your_path/your_file.mp3");
// To set image
ImageView imageView1 = (ImageView)findViewById(R.id.iv1);
imageView1.setImageBitmap(BitmapFactory.decodeFileDescriptor(afd_iv1.getFileDescriptor()));
// To set sound
try {
mpbg.setDataSource(afd_mpbg.getFileDescriptor(), afd_mpbg.getStartOffset(), afd_mpbg.getDeclaredLength());
mpbg.prepareAsync();
mpbg.start();
} catch (IllegalStateException e) {
Log.w("Error=====", "Failed to prepare media player", e);
}
Via InputStream:
// This one works with an image file and a media file.
// Get a ZipResourceFile representing a specific expansion file
ZipResourceFile expansionFile = new ZipResourceFile(filePathToMyZip);
// Get an input stream for a known file inside the expansion file ZIPs
InputStream fileStream = expansionFile.getInputStream(pathToFileInsideZip);
Via Uri
// This one can use in almost thing such as jpg, mp3, mp4, pdf, etc.
// You need to create a new class to override APEZProvider
public class ZipFileContentProvider extends APEZProvider {
@Override
public String getAuthority() {
return "com.bluewindsolution.android.sampleapp";
}
}
// You need to add <provider> in AndroidManifest.xml
<provider
android:name="com.bluewindsolution.android.sampleapp.ZipFileContentProvider"
android:authorities="com.bluewindsolution.android.sampleapp"
android:exported="false"
android:multiprocess="true"
>
<meta-data android:name="mainVersion"
android:value="1"></meta-data>
</provider>
// After that, you can use it any time by this code:
String filename2 = "image/i_commu_a_1_1_1_1.jpg"; // suppose you store put your file in directory in .obb
String uriString2 = "content://com.bluewindsolution.android.sampleapp" + File.separator + filename2;
Uri uri2 = Uri.parse(uriString2);
imageView2.setImageURI(uri2);
// Filename inside my expansion file
String filename = "video/v_do_1_1_1.mp4"; // Suppose you store put your file in directory in .obb
String uriString = "content://com.bw.sample_extension_download_main" + File.separator + filename;
Uri uri = Uri.parse(uriString);
v1 = (VideoView)findViewById(R.id.videoView1);
v1.setVideoURI(uri);
v1.start();
