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?

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'm developing a UWP app for tablet and i need to generate a PDF with data from SQLite. I need to do this completely offline because where I will use the app there is no connection. What could I do?
I'd prefer not to use paid libraries like Syncfusion and XFinium so I'm trying to find an alternative solution.
I tried with iTextSharp but unfortunately I can't find a good documentation to render a complex PDF or to export a Bitmap generated from a Grid Component to a PDF File.
Why not render your data into a webpage displayed with a WebView control? Then you can use any permissive licensed javascript library to generate the PDF.
If it hasn't changed much, then you can only send text back and forth between your WebView and UWP app, but that's workable. Your final PDF result can be read back as a base64 encoded string.
A very quick search found this one that seems easy to use and you can just download the source to put into your app:
https://github.com/MrRio/jsPDF
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.
We are working on creating mobile app using sencha touch frame work. one of our requirements is when user hits view pdf, the user entered form details which stored locally has json format should be rendered and view as pdf and also it can be saved as a pdf locally.
i found that itext is one of the java library which is widely used for pdf generation. but i couldn't find any article inter relating both sencha touch and itext. let me know is that a possible way or any other method available for json to pdf generation in sencha touch.

java has nothing to do with javascript.
A quick Google search of "javascript pdf generation" lists some libraries that may work but getting them to run on a device might be more trouble than its worth id look at submitting the form results to a server and downloading the resultant PDF.
this might point you in the right direction:

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.
