How can I pass a url to an android app using href?

I'm trying to pass a link to mpv-android. I want to do it via href using intents
Something like this :
<a href="mpv//https://video/url.mp4">
But its not working. Can someone help me with this.
mpv-android github:https://github.com/mpv-android/mpv-android/blob/master/app/src/main/AndroidManifest.xml

Try using an intent

Found the solution here. Since the manifest filters depending on MIME type or URLs with a few select extensions (mkv, mp4, webm, m3u, ...) you need to trick Android into opening mpv anyway by specifying a valid-looking type.

Use drawable resources for Gboard sticker pack

Is it possible to use drawable resources bundled in your app instead of hosted images for adding stickers to Gboard?
Google provides the following code snippet here to show how to add a sticker to Gboard and it looks like the only way is to reference a hosted image:
new Indexable.Builder("Sticker")
.setName("Bye")
// add url for sticker asset
.setImage("http://www.snoopysticker.com?id=1234")
// see: Support links to your app content section
.setUrl("http://sticker/canonical/image/bye")
// Set the accessibility label for the sticker.
.setDescription("A sticker for Bye")
// Add search keywords.
.put("keywords", "bye", "snoopy", "see ya", "good bye")
.put("isPartOf",
new Indexable.Builder("StickerPack")
.setName("Snoopy Pack")
.build())
.build())};
All help is greatly appreciated!

String drawableResourceUri = Uri.parse("android.resource://your.package.name/drawable/yourfilenamewithoutextension").toString());
Add this string to your setUrl() method.

Google's AppIndexing sample project has an example of the files being generated at run time. This isn't exactly a Drawable resource but the same strategy can likely be used.

How to save GLSurfaceView rendering to file?

I'm using VideoSurfaceView extends GLSurfaceView to render filtered video. I'm doing it buy changing the fragment shader according to my needs. Now I would like to save/render the video after the changes to a file of the same format(Ex. mp4 - h264) but couldn't find how to do it.
I am using this library - https://github.com/krazykira/VidEffects.
Any experts here?

I would try and use the MediaProjection API. Here is an Google sample for this api. Notice: this might not work on the new emulators.

Google Drive Custom Thumbnail for Standard MIME Type

I have yet another pesky question for people who understand how Google Drive SDK works. On Android platform, I am creating my own custom thumbnails for JPEG image files ( thumbnail is a reduced JPG of the most important detail of the parent image ), The size is a bit non-standard - 384 x 128px, but well within limits stated in the documentation. So, the code goes like this:
// thumbnail
String myThumb = "test.tnl";
Thumbnail tn = new Thumbnail();
tn.setMimeType("image/jpeg");
tn.setImage(Base64.encodeBase64String(myThumb.getBytes()));
// define meta-data
File body = new File();
body.setTitle("test.jpg");
body.setDescription("bla bla");
body.setMimeType("image/jpeg");
body.setThumbnail(tn);
File gooFl = drvSvc.files()
.insert(body, new FileContent("image/jpeg", new java.io.File(test.jpg)))
.execute();
and executes flawlessly (there are more 'body' elements I don't list here) and everything works like a charm. But when I download the image, my thumbnail is gone, replaced by standard Google thumbnail - s220 type.
I did notice the documentation statement:
As with indexable text, Drive automatically generates thumbnails for many common file types. For shortcuts and other file types Drive can not render, you can provide a thumbnail image generated by your application.
Reading it ambiguously, I was hoping that by supplying my own thumbnail to a known MIME type, I will keep Google Drive from generating its standard one, but it probably is not the case. So the question remains. Is there a solution to my problem? Having custom thumbnails for standard "image/jpeg" MIME types? Or is there a work-around, perhaps another custom field I can stick some 10Kb of binary data in? I need the thumbnails in my Android viewer - another app.
Thank you, sean

Google Drive will only use custom thumbnails for non-standard MIME types, so you can't override the one for jpeg. Your app can use a custom file property to store and read proprietary data:

Android SKIA Image Decoding

HI,
I am currently studying how Android decode and image file. When I checked the code, it seems like it is calling the SKIA library. But, how do I know what are the image file format supported by android/skia basing on the source code?
I am not an expert in programming, so I am still trying to understand C++ and Java language.
I am now lost at SkImageDecoder* decoder = SkImageDecoder::Factory(stream); inside the BitmapFactory.cpp (JNI file). SkImageDecoder::Factory(stream) seems to be a template.
Anyone can explain me what is happening inside SKImageDecoder::Factory()? Any feedback will be greatly appreciated.
Thanks,
artsylar

In skia/include/images/SkImageDecoder.h file, there is the image list decoding supported by Skia:
enum Format {
kUnknown_Format,
kBMP_Format,
kGIF_Format,
kICO_Format,
kJPEG_Format,
kPNG_Format,
kWBMP_Format,
kWEBP_Format,
kLastKnownFormat = kWEBP_Format
};
In SkImageDecoder::Factory(stream) function, it will new a decoder instance according to analyze the Stream's header.

By looking at the source codes of Android, I think the following image formats are supported.
ICO (Windows ICON image format), BMP, JPEG, WBMP, GIF, and PNG.
Please correct me if I am wrong. Thank you.

PNG, JPEG, and GIF are the supported formats. The primary formats used on Android are PNG and JPEG.
