I want to store text files with contact information in my app, and I want that information to be stored securely. The Android developers' website says I can store sensitive data in internal storage, but that's for an Android app and I'm using Xamarin.Forms to make my app for Android and iOS. How do I store something in internal storage on Xamarin.Forms and should I do something different for the iOS version?

I am looking for integrating Media Service from azure to Xamarin Android for live broadcasting and viewing the live with on demand videos. For example I need to implement the live video broadcasting like a Facebook app using Azure Media Services and also view the live and archived videos from blob storage. I am unable to get the resource to implement that from official documents of Azure and Xamarin and through the Xamarin University.
So I am here to learn this which will be useful to almost every one willing to implement this kind of features in feature.
There is a official video showing the upload of a video recorded using xamarin application to Azure Media Service and viewing back on the Xamarin app the link is as follows, but there is no approach for making a live broadcasting possible through the same.

Xamarin.Android is not compulsory like it may be from Xamarin Forms also the thing is like we just need the android part, I will be happily looking forward to take any kind of help you can offer to get this working.
Scope of App Requirement/Workflow::
1) App should be able to broad cast live (like going live on Facebook application)
2) That should be capable to view the live broadcasts (like we can stream the live content in Facebook application)
3) That should be able to view the archived videos in blob storage (I know how to access the blob storage and download the video to view it on mobile but I don’t know the process to stream the video while it is being downloaded in the background like it does in Youtube or Facebook application).
Using Xamarin.Android and Media Service in Azure for live broadcasting
You could refer to the xamarin-azure-businessreview sample.

We're planning to build a Xamarin app, where you can watch some videos that are hosted on microsoft Azure. Does the azure blob storage support streaming to my mobile app or can i only download the files?
The video urls shouldn't be exposed to public, as mentioned here.
Has anybody experience in this? I didn't find any reliable infos on the web.
Very important thing here - streaming and live-streaming. If you would like to just upload video files to Azur Blob and access them in the mobile app this is possible. I did tests with .mp4 (I did not test other formats) files and once they were uploaded I could play them in the mobile app without any problems.
You do not have to worry about the access too - you can secure URLs with Shared Access Signature or Storage Account Key.

I'm currently creating my first application using Xamarin PCL(without Xamarin.Forms) and Azure Mobile App. What would be the best approach to use only one instance of MobileServiceClient across all applications? If it's not possible to use it from PCL, then is there any way to do it the same way, but only across iOS app?
If you're referring to code sharing when you say instance, the Azure Mobile Apps Client SDK enables you to do that. You can consume the SDK from your PCL and use your PCL from your platform targets/projects.
Have anyone used azure media service with xamarin. I am trying to make an portable library which can upload / retrieves video asseset from a standard azure media server. However I am not able to install the nuget package into my project.
Can anyone point me in the right direction
I don't think the default azure media libary is a portable library therefore you cannot add it to your portable library project.
You could however implement this using the available rest documentation.
Media Services Rest Api
We've done something similar for access to blob storage. To avoid having to reference all the azure storage libraries in all our projects.
I have used the info on this link to create a windows phone sample of uploading images to Azure Blob Storage by using Mobile Services.

I want to now try and use Xamarin Component of Azure Mobile Services to achieve the same result from Android and iOS. Does Xamarin component have support for this? Also, if anyone has done this before from Xamarin, could you please point me in the correct direction? I couldn't find much information on this topic of using blob storage from within Xamarin for Android or iOS
You can use Zach's Blob Uploader:

This is a lot simpler than using the AMS features for this (but lacks the features like expiration of the url and some auth bits).
You really want to use a web service between your blob storage account, and your Mobile app, unless your app is allowing users to access their own blob storage accounts. If you are determined to make a Xamarin app use Blob storage directly, you can use this Mono port.. it takes a bit of work to get it functioning. It also won't handle some functions in Azure Blob storage. I could only get "Download" to work. Deleting.. and uploading functions were broken. Maybe I screwed up the port to Xamarin.
Mono Azure sdk port
By using that sdk port, I was able to make an IOS app called "Blob Client" that allowed users to at least download their files on IOS. Made it as a tool for myself.. for a project I had, but then went ahead and put it out on the store.
