Android Camera preview with funhouse mirror effect

I created a android small app that uses the front facing camera to shoot a selfie. But what i want to accomplish is a funhouse mirror effect.
I searched the internet trying to find a solution or a way to do this but i am guessing i am searching for the wrong terms here:
Sample Image
Can someone push me in the right direction or how this is made? I searched for morphing, distortion etc.
What i have right now:
A basic camera app wich is saving a taken photo using the Camera2 API in Android SDK 23
Just only Camera2 API are not enough to develop an app which is like mentioned you. You should use computer vision libraries such as OpenCV or OpenGL.
First of all, please check it out for creating theoretical background.
Here is an example application which is using OpenCV and it is about funny effects.
This can be another reference application which is about fun house effects and it was developed by using GLSL.
Also this post can be helpful for you.
Moreover, you can check it and it out. And, you can use "image warping" term to search to find solutions for your problem on internet.

android java add edit contacts google accounts

I want to access (add, edit) contacts of Google accounts on an android device. I'm using Android Studio.
I've found couple posts on http://stackoverflow.com:
Android - sync contact add programatically to google account
Xml model for adding contact to google contacts
However, first mentions problem and have no answer, second has only some parts of code and both do not show how to choose account if there are sereral on a device.
I foresee it could be considered broad question, however, if OK, please advice how to do my task with less code and setup (e.g. Maven or jar libraries or else) and with specific code samples - via Google API or some other way?
I think you'll be better off delegating this kind of work to the system, using Intents. You can have a look at how Google recommends to do it here
I hope this helps!

How to build an Android widget that plays video

I'm wanting to build an Android widget for my phone that streams a video from a link on button click. I've searched tutorials on Google but I'm still having difficulty understanding how I'd achieve this.
Does anybody have an example of something similar to this or know of any good tutorials to get me started?
Cheers
You can use android native VideoView. It can even play online streaming videos.

Facebook Android sdk and Facebook app overlapping

I have developed an Android game that integrates facebook SDK for checking if one has liked and sharing results.
I heard from my mate that he had problem that made him unable to use the like for reward feature on my app, so I decided to install facebook app myself to check out the problem.
For some reason if I am trying to access the fb api reading data from URL "https://api.facebook.com/method/pages.isFan?format=json&access_token=ACCESS_TOKEN&page_id=PAGE_ID" it opens up facebook app on Android which only flashes and then turns off.. How can I avoid this or is there better way to check if one has liked my page in order to give him reward?
I haven't used the Facebook API, but the Facebook app is probably opening because it's listening for broadcast Intents to "api.facebook.com". You could explicitly send the intent to a browser package instead, but this isn't a good solution as there are many browsers.
I would try to do a HTTPS request using a Loader to fetch and parse the json. Have you tried this yet?
I can't paste any code right now, sorry.
From your comment to above Answer , Glad to know that you solved your problem,
Here is the answer for your Question
is there better way to check if one has liked my page
You can surely use FQL - Facebook Query Language to do this, given under the developer documentation in Facebook site.
There are Two different table
1.Page - where you can get all the detail about the page
2.Page_Fan - which you can use to know the fan-id for the page
