This is the link for the app Playbook for Developers.
these are examples of animations::
I think, this app use AnimatedVectorDrawable.
However it is very difficult to create a complex animation, unless there is any tool that converts vectors as svg2android made ools as Adobe Illustrator into vectors android can identify.
I would be most grateful if you tell me how to make these animations and if there is any tool to make using tools such as Adobe After Effects.
Unzip the apk and you will find out that they are gif files.
And it seems that they are using https://github.com/koral--/android-gif-drawable to load gif files.

I'm trying to build a mobile app (react-native or native languages) that will be able to take xmp file (in other words is presets of photos) and implement its data on other photo, or implementing dng settings on another photo.
What I'm trying to understand if that is even possible, to use Lightroom presets outside of Lightroom App.
Did someone here succeed to implement his\her own Lightroom preset without using Lightroom on mobile?
I dont think so cuz every app has different sets of editing skills, the best I think you could do is to create an app from where a user will click on DNG and it will open in Lightroom.
I believe there are a bunch of questions related to this, but they are all outdated.
I'm looking for a way to render a panorama/360 picture viewer in React Native. So far, all the libraries that try to use Google's VR SDK are outdated or broken, and not usable at all.
I have also tried to use a WebView (with react-360), but web views are just way too slow, doubles RAM usage, and worst of all, can't be used to render 360 pictures stored on the device.
I guess that another option would be to grab an OpenGL library and try to implement it myself, but that's probably a lot of work if there's something made already.
We've recently published the panorama viewer we are using in our apps. Hope it can help you too. #lightbase/react-native-panorama-view
as I state on the title, I want to develop a project that having ability to open PDF file within the App (React Native), then later we can add annotation, notes, and sign on the PDF (put writing).
The pdf is from the server, so I assume we can call some kind of library that can open pdf and edit and have those features.
I tried browsing about it and found that PSPDFKit can be a solution, but the pricing is pretty much expensive. Is there any other library that can be use for this purpose?
We are going to develop a mobile app (iOS and Android), which should provide downloading and storing several user-selected PDF files and viewing them within the app (iOS with WebView) or with an external PDF Viewer (Android).
My Question is: Is this possible with Trigger.io? I didn't find anything concerning this in the official documentation. Can we do something with the file or the child browser / tabs module? If yes, do you have any examples?
Note: We will use Backbone.js and jQuery Mobile as additional libraries.
The Android webview doesn't allow for inline opening of PDFs - you can test that by opening e.g. http://trigger.io/cross-platform-application-development-blog/wp-content/uploads/2012/05/trigger.io-whitepaper.pdf in your stock browser.
On iOS, you can use:
forge.tools.getURL('my_file.pdf',
function (file) {
forge.tabs.open(file);
}
);
But that won't work on Android (tested on 2.3, 3 and 4.0).
Short answer - yes.
Downloading, storing, then showing/referencing later can definitely be done. Check out the forge.file documentation.
I have not tried the child browser feature yet. Although the tabs module will work, I think its best to just let the device (and its user settings) decide how to display/render the PDF. I am only saying this because my devices (especially the Android ones... 2.3 and 4.x) tend to behave differently. Either way... the device's "back button" always gets me back to where I left off in my trigger.io app.
How can I create an animated .gif file from a movie I have?
I guess it is pretty simple in objective-C and cocoa, by using the QTKit, to extract images from a movie, now how can I glue them together as an animated gif?
I don't think there's anything built into OS X for creating animated GIFs. Your best bet would be to look at the gifsicle project. You could either call it via command-line, or borrow the code if your license allows it. (it's GPL)
http://www.lcdf.org/gifsicle/
There is a pretty good lib (even if 'old') for this task (and other kinds of image processing): libgd. It appears it is built into Mac OS X or easly installable through MacPorts. Here some doc about animated GIF creation from single images.
