Set thumbnail to an Intent for VideoView

I have to play a video in one of my screens of Android and I am using Video View intent for the same. The video gets played but there is no thumbnail appearing on the launch of the screen.
My code is like this
#OnClick(R.id.icon_play)
protected void playVideo(){
String videoUrl="https://someUrl/Video/v07.mp4";
if(!videoUrl.isEmpty()) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(videoUrl));
intent.setDataAndType(Uri.parse(videoUrl), "video/mp4");
startActivity(intent);
}
}
By thumbnail, I mean that when the screen is launched each video should have an image of its own. (something like YouTube)
I tried seekTo() for attaching the thumbnail, but it didn't work.
Please Help. Thanks.

I solve the problem using MediaMetaDataRetriever.
The code goes like this-
public static Bitmap retriveVideoFrameFromVideo(String videoPath)
throws Throwable
{
Bitmap bitmap = null;
MediaMetadataRetriever mediaMetadataRetriever = null;
try
{
mediaMetadataRetriever = new MediaMetadataRetriever();
if (Build.VERSION.SDK_INT >= 14)
mediaMetadataRetriever.setDataSource(videoPath, new HashMap<String, String>());
else
mediaMetadataRetriever.setDataSource(videoPath);
// mediaMetadataRetriever.setDataSource(videoPath);
bitmap = mediaMetadataRetriever.getFrameAtTime(-1,MediaMetadataRetriever.OPTION_CLOSEST);
}
catch (Exception e)
{
e.printStackTrace();
throw new Throwable(
"Exception in retriveVideoFrameFromVideo(String videoPath)"
+ e.getMessage());
}
finally
{
if (mediaMetadataRetriever != null)
{
mediaMetadataRetriever.release();
}
}
return bitmap;
}
Note that : Because my video link was in the form of server URL, that's why createThumnailUtils was returning a null when video Url was passed through it.
The below code works fine when the video is coming from local storage.
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail("URL", MediaStore.Images.Thumbnails.MINI_KIND);
BitmapDrawable bitmapD = new BitmapDrawable(thumbnail);
VideoView.setBackground(Drawable bitmapD);
Hope this helps someone!!

Just looked at another example. Not 100% sure if it's going to work but worth a try.
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail("URL", MediaStore.Images.Thumbnails.MINI_KIND);
BitmapDrawable bitmapD = new BitmapDrawable(thumbnail);
VideoView.setBackground(Drawable bitmapD);
Please note, I have written this over phone so there might be spelling errors.
Let me know if this works or if you find another alternative

this may be used i am using this method for thumbnail image of video on my list view of video player..
Cursor cursor = mContext.getContentResolver().query(
MediaStore.Video.Media.EXTERNAL_CONTENT_URI, proj,
MediaStore.Video.Media.DISPLAY_NAME + "=?",
new String[]{localItem._display_name}, null);
cursor.moveToFirst();
long ids = cursor.getLong(cursor
.getColumnIndex(MediaStore.Video.Media._ID));
ContentResolver crThumb = mContext.getContentResolver();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(
crThumb, ids, MediaStore.Video.Thumbnails.MICRO_KIND,
options);
itemHolder.thumbImage.setImageBitmap(curThumb);
curThumb = null;
cursor.close();
try this way it may be helpful
above ans is now deprecated.
new updated answer with fast one solution
we just have to give the video data path
Bitmap bmThumbnail;
bmThumbnail = ThumbnailUtils.createVideoThumbnail(arraylist.get(i)._data, MediaStore.Video.Thumbnails.MICRO_KIND);
itemHolder.thumbImage.setImageBitmap(bmThumbnail);
where arraylist.get(i)._data => path of video.
and best way is to use Glide or any other image lodging async library for smooth scrolling of listview.

Grab video thumbnail and show it in a Gridview in android

I am developing a module for which i want to show all the user's videos from sd card into a Gridview. I have grabbed video file paths in usual way (Checking if file or directory and save if its a file) in a arraylist and grabbed its bitmap thumbnail with following code:
Bitmap bmThumbnail = ThumbnailUtils.createVideoThumbnail(VideoValues.get(position).getAbsolutePath(),
Thumbnails.MINI_KIND);
Obviously this code runs in a background thread. But the only problem is that the gribview still freezes a lot while scrolling. According to me the main problem is extracting the bitmap from video, which takes a lot of time. Can anyone suggest me a different way to get bitmap from video and how it in a grid ? I have seen the smooth behavior in other apps like Facebook, etc. But I cannot figure out as to how that can be done.

please use below method for retrive video thumbnail from video
#SuppressLint("NewApi")
public static Bitmap retriveVideoFrameFromVideo(String videoPath)
throws Throwable
{
Bitmap bitmap = null;
MediaMetadataRetriever mediaMetadataRetriever = null;
try
{
mediaMetadataRetriever = new MediaMetadataRetriever();
mediaMetadataRetriever.setDataSource(videoPath);
bitmap = mediaMetadataRetriever.getFrameAtTime();
}
catch (Exception e)
{
throw new Throwable(
"Exception in retriveVideoFrameFromVideo(String videoPath)"
+ e.getMessage());
}
finally
{
if (mediaMetadataRetriever != null)
{
mediaMetadataRetriever.release();
}
}
return bitmap;
}

Download image from new Google+ (plus) Photos Application

Recently Google added the Photos app for Google+ (plus) and it shows up when you launch an Intent to choose an image. However, if I select an image from Google+ Photos and try to use it in my application none of my current logic is able to return a usable URI or URL to actually get an image that I can download and manipulate. I'm currently using the "common" methods to try to manipulate the URI that can be found here on Stack Overflow and elsewhere. I can provide code if needed, but at this point I think it's kind of irrelevant since it works well for everything else except this new app. Any ideas on how to get a usable image?
The URI looks something like the following:
content://com.google.android.apps.photos.content/0/https%3A%2F%2Flh5.googleusercontent.com%<a bunch of letters and numbers here>
The MediaColumns.DATA info always returns null and the MediaColumns.DISPLAY_NAME always returns image.jpg no matter what I select from the Google Photos app. If I try to paste everything from https to the end in my browser, nothing comes up. Not sure how to get usable info from this.

When receiving the data intent, you should use the contentResolver to get the photos.
Here's what you should do:
String url = intent.getData().toString();
Bitmap bitmap = null;
InputStream is = null;
if (url.startsWith("content://com.google.android.apps.photos.content")){
is = getContentResolver().openInputStream(Uri.parse(url));
bitmap = BitmapFactory.decodeStream(is);
}

I did faced issues selecting images from new Google Photos app. I was able to resolve it by below code.
It works for me, basically what i did is i am checking if there is any authority is there or not in content URI. If it is there i am writing to temporary file and returning path of that temporary image. You can skip compression part while writing to temporary image
public static String getImageUrlWithAuthority(Context context, Uri uri) {
InputStream is = null;
if (uri.getAuthority() != null) {
try {
is = context.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(is);
return writeToTempImageAndGetPathUri(context, bmp).toString();
} catch (FileNotFoundException e) {
e.printStackTrace();
}finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return null;
}
public static Uri writeToTempImageAndGetPathUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
P.S. : I have answered a similar question here

You have to use projection in order to get ImageColumns.DATA (or MediaColumns.DATA):
private String getRealPathFromURI(Uri contentURI) {
// Projection makes ContentResolver to get needed columns only
String[] medData = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(contentURI, medData, null, null, null);
// this is how you can simply get Bitmap
Bitmap bmp = MediaStore.Images.Media.getBitmap(getContentResolver(), contentURI);
// After using projection cursor will have needed DATA column
cursor.moveToFirst();
final int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}

How can I verify image URI is valid in Android?

I am building my own contact picker, because I needed multi-select support. Everything is working fine, except for one small problem with the contact images.
For contacts who don't have images I am showing a "no image" image. This works fine for contacts in the phone's address book. I am having a problem however when it comes to images from my google contacts.
Most of my google contacts do not have photos. However, when i query the Contacts database for photos, it still returns a URI for them of the form of content://com.android.contacts/contacts/657/photo (which is the same format as for contacts who do have a photo.
Then when I try to assign the photo to a QuickContactBadge, using bdg.setImageURI(pic); it sets it to essentially a blank picture, and logs a silent INFO message stating:
INFO/System.out(3968): resolveUri failed on bad bitmap uri:
content://com.android.contacts/contacts/657/photo
I need to know how I can either
a) validate the URI or
b) catch the INFO message above
c) query the imageview/badge to see if it found a valid image
so that i can assign these contacts my "no image" image.
How can I go about doing this?
EDIT 20110812.0044
I have tried adding this to my code as per Laurence's suggestion (which he's since removed):
// rv is my URI variable
if(rv != null) {
Drawable d = Drawable.createFromPath(rv.toString());
if (d == null) rv = null;
}
While the google contacts now get my "no image" image, ... so do all the other contacts, including ones that do in fact have images.

Okay, I figured out how to do this after poking through the ImageView source code. It is actually using the QuickContactBadge's own methods, but if necessary, one could always extract the relevant code from the Badge/ImageView control here.
After setting the QCB's image, I check to see if its drawable is null, instead of trying my own (as per Laurence's suggestion). This works better, because there is actually a whole slew of checking code the ImageView widget uses.
Here is my final code:
bdg.setImageURI(pic);
if(bdg.getDrawable() == null) bdg.setImageResource(R.drawable.contactg);
This works perfectly as I was hoping and expecting.

Just to answer the question on how to check the (data) value in the MediaStore:
ContentResolver cr = getContentResolver();
String[] projection = {MediaStore.MediaColumns.DATA}
Cursor cur = cr.query(Uri.parse(contentUri), projection, null, null, null);
if(cur != null) {
cur.moveToFirst();
String filePath = cur.getString(0);
if (filePath == null || filePath.isEmpty()) {
// data not set
} else if((new File(filePath)).exists()){
// do something if it exists
} else {
// File was not found
// this is binary data
}
} else {
// content Uri was invalid or some other error occurred
}
Inspiration taken from: https://stackoverflow.com/a/7649784/621690 and others.
There is also the column SIZE that might be checked: http://developer.android.com/reference/android/provider/MediaStore.MediaColumns.html#SIZE
It sounds like it should contain 0 if there is no data value. But I wouldn't know what it contains if data is a file path.

It could be that the images are not downloaded. I faced a similar problem with whatsapp images.
One way to go about this could be like below:
InputStream is = null;
try {
is = context.getContentResolver().openInputStream(myuri);
}catch (Exception e){
Log.d("TAG", "Exception " + e);
}
if(is==null)
//Assign to "no image"

Based on the code (http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/1.5_r4/android/widget/ImageView.java) my solution for checking Uri:
public static Uri checkUriExists (Context mContext,Uri mUri) {
Drawable d = null;
if (mUri != null) {
if ("content".equals(mUri.getScheme())) {
try {
d = Drawable.createFromStream(
mContext.getContentResolver().openInputStream(mUri),
null);
} catch (Exception e) {
Log.w("checkUriExists", "Unable to open content: " + mUri, e);
mUri = null;
}
} else {
d = Drawable.createFromPath(mUri.toString());
}
if (d == null) {
// Invalid uri
mUri = null;
}
}
return mUri;
}

I am using this code for Uri that has file:// authority
Uri resimUri = Uri.parse(path_str);
File imgFile = new File(resimUri.getPath());
if (imgFile.exists()) {
// file exists
}else {
// file is not there
}

cover art on android

I am developing a sort of media player for android. The question is how can i get the cover art of audio file on android.
For example the default android media player shows album covers when listing albums, how can i get this artworks.

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);
ContentResolver res = context.getContentResolver();
InputStream in = res.openInputStream(uri);
Bitmap artwork = BitmapFactory.decodeStream(in);
More complete sample code can be found in Android Music player source here https://github.com/android/platform_packages_apps_music/blob/master/src/com/android/music/MusicUtils.java method getArtworkQuick.

You can use
MediaMetadataRetriever
class and get track info i.e. Title,Artist,Album,Image
Bitmap GetImage(String filepath) //filepath is path of music file
{
Bitmap image;
MediaMetadataRetriever mData=new MediaMetadataRetriever();
mData.setDataSource(filePath);
try{
byte art[]=mData.getEmbeddedPicture();
image=BitmapFactory.decodeByteArray(art, 0, art.length);
}
catch(Exception e)
{
image=null;
}
return image;
}

I don't know why everybody is making it so complicated you can use Glide to achieve this in simplest and efficient way with just 1 line of code
Declare this path in App Constants -
final public static Uri sArtworkUri = Uri
.parse("content://media/external/audio/albumart");
Get Image Uri using Album ID
Uri uri = ContentUris.withAppendedId(PlayerConstants.sArtworkUri,
listOfAlbums.get(position).getAlbumID());
Now simply display album art using uri :-
Glide.with(context).load(uri).placeholder(R.drawable.art_default).error(R.drawable.art_default)
.crossFade().centerCrop().into(holder.albumImage);
Glide will handle caching, scaling and lazy loading of images for you.
Hope it help somebody.

Here i can attach one function that is return album art from media store .
Here in function we just have to pass the album_id which we get from Media store .
public Bitmap getAlbumart(Long album_id)
{
Bitmap bm = null;
try
{
final Uri sArtworkUri = Uri
.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);
ParcelFileDescriptor pfd = context.getContentResolver()
.openFileDescriptor(uri, "r");
if (pfd != null)
{
FileDescriptor fd = pfd.getFileDescriptor();
bm = BitmapFactory.decodeFileDescriptor(fd);
}
} catch (Exception e) {
}
return bm;
}

Based on your comments to others, it seems like your question is less about Android and more about how to get album art in general. Perhaps this article on retrieving album art from Amazon will be helpful. Once you have a local copy and store it as Nick has suggested, I believe you should be able to retrieve it the way Fudgey suggested.

Android only recognizes files named "AlbumArt.jpg" as Album Covers. Just put the pictures with that name in the album folder and you'll be fine..

I don't know if you read that google is making Stackoverflow the official Android app development Q&A medium but for beginner questions... Now, I know nothing about developing in andriod, but a quick search of the Android Developers site, I found this:
MediaStore.Audio.AlbumColumns
Hopefully it'll help.
