Launch an app from within another (iPhone)
I have designed sample applications and installed in the iPhone.
First application has a button in it, and i would like to get invoked the second application when the button is pressed. I am surfing to see the feasibility of it, but not sure if i have missed it.
Could someone guide the direction?
You want to look at employing an URL scheme for your second application.
If you mean you want to start another application from yours, you have to use URL Schemes.
Just register a custom scheme on your other app and call such URL from the first one.
Here there is a tutorial that might help you:

You can use URL SCHEME, please see the tutorial

Since a while, but without success, I'm trying to achieve a cross-platform solution that makes me able to use a custom camera with custom functionalities. However, no one on the internet seems to get it done over each platform (Often, only Android & iOS are implemented, but no UWP) and I still don't understand why...
I've been searching for the past months how to make something, like a service, a dependency service like, from which you can get the stream/frames of the camera. Once you get it, be able to put it into an Xamarin.Forms.Image.
The principle of this conception would allow developers to implement functions, inside of the dependency service, such as taking video or taking pictures from the native stream camera.
You could say "But you can already use NuGet as Xam.Plugin.Media from James Montemagno.". Yes, but with his package, you call the native built-in camera so you can't implement your own design or your own functionalities..
So my question is: "Does someone has any tips or any project that can help to realize this project/idea?". If I can make it work, then I will create a project on my public GitHub, in order to help future people who would like to realize it.
Thank for any help
PS: There is some results about some researches I made: https://forums.xamarin.com/discussion/comment/284359/#Comment_284359
This article looks to be similar to what you are after:
Full Page Camera in Xamarin
It derives a camera page from ContentPage then creates platform specific custom renderers based on PageRenderer.
Bonus - there is source code on GitHub
I am using Multi-peer connectivity framework and have tried Apple example it works fine, but I want to modify it and instead of using inbuilt browser view controller UI i want to do it with my own UI / code , is it possible to discover devices without the inbuilt UI ?
Please help.
See my answer here. I think you'll find the answer there but the short of it is that it is possible. Here is a link to a post at NSHipster that will walk you through the work too.

Unable to create live tile inside Windows 8 application
is it possible to use live tiles inside a page? I know how to configure tiles for start menu, but I don't know how to obtain a similar effect inside my app. Thank you
You can use the LiveTile control that comes with Callisto.
You could create the effect within an application, but the specific mechanism used for the Start screen is not directly available within the context of an application.
From another post in StackOverflow, you may be able to reuse/port code from the Windows Phone 7 toolkit. There's a number of applications in the Windows Store as well (search for "tile") that provide interfaces for designing tiles, and some may have incorporated similar functionality.
Also from this post, looks like Telerik may have a solution.
I would like to access a camera attached to my system. basically i would like to capture an image using the code retirieve the image. can someone suggest me a good framework. I went through JMF, but it was last updated 7 years ago. FMJ also lacks proper documentation. Is there any framework available which is good and has good userbase?
Xuggler is pretty cool. It has tutorials too.

I'm working on a Cocoa app targeting Leopard and above, and I'm thinking about adding a crash reporter to it (I'd like to think my app won't crash, but let's get real here). I have some mostly conceptual questions before I really get started.
1) How does this work conceptually, knowing when there's a crash and bringing up a reporter? Do I have a daemon running looking for a crash, or do I wait until my app is launched next time to report?
2) Can this be done in Cocoa? Or would I have to dip into Carbon or IOKit or somesuch?
3) Is this even a good idea? Mac OS X already has a built in crash reporter, but as a developer I don't get to see the crash logs. I don't think my app will be crashing often, frankly, but I just don't want to be naive but this sort of thing.
What are your thoughts and opinions regarding this?
I've had a lot of success with UKCrashReporter. The code is straighforward and easy to modify to match the L&F of your app.
PLCrashReporter looks interesting, though.
I'd stay away from Smart Crash Reporter just because many users (rightfully) don't appreciate your app injecting code into unexpected places and it strikes me as a fragile (perhaps dangerous to use in a released app) approach.
Others have answered the question well and pointed to some good example code.
Coding it yourself is fairly simple. The strategy generally is:
catch appropriate signals
launch a separate crash reporter app that lives inside your application's bundle
the crash reporter app then finds the latest crash log entry for your app and sends it to you via whatever method you desire (POST, email, etc)
I've also rolled my own: SFBCrashReporter
There is a small post on my blog about it.
I have seen a few apps use Smart Crash Reporter or perhaps some variant of it. When your application crashes, it will bring up the usual Apple crash dialog with an extra button which says "Send to both Apple and You"
I would shy away from Smart Crash Reporter for the single reason that it has a bad taste for a lot of users, and is a good way to get bad press for your app (deserved or not) PLCrashReporter or UKCrashReporter http://zathras.de/angelweb/sourcecode.htm they will give some ideas about what to do and how to do it in ways that don't inject into other code space.
Another option is Google's Breakpad. It has a Cocoa framework wrapper, and is compatible with Mozilla's Socorro server. It's used by Firefox, and the Cocoa framework is used in the current betas of Camino. The client-side integration is pretty easy, but I've never looked at what it takes to run an instance of the Socorro server.
I'm using ILCrashReporter and it works really nicely. The method is email based so it works well with Fogbugz.
