I have an idea to make an AR android app using Vuforia and Unity3d with Android Studio. I have never worked with Vuforia so i don't know if it is possible or not.
Basically in app user can set target for Vuforia through mobile camera and he can also assign which object is displayed on that target. For example user takes a picture of a glass as a target and he also sets a video of how glass is made (from uploading or through youtube link). And then video is augmented on glass target.
i don't know if its possible? and how?
any tutorials and guidance would be appreciated.
thanks :)
In order to track an image target you have to create database in your case a user defined one. And this database should be created using Target Manager from Vuforia webpage. Then you have to download this database and add it to your Unity project like this. Therefore, I do not think you can create image targets while your game is running.

I'm trying to build a simple Android Studio app that can read text from images: the idea is to use the camera to take a picture of a single document page and then do some OCR.
I've already tried to use my OCR on documents that I scanned manually with the Google Drive app and the result is satisfying, but when I try with raw pictures from the camera, it doesn't work anymore.
1) Is there a way to use Google Drive API (or similar) to obtain a good quality scan from the camera without reinventing the wheel?
2) Also, is there a way to do the whole process from the camera to the final text with known tools?
Any help would be really appreciated!
You Can use an Intent in your app to use the camera and resources from the google drive, it's like a link that drives the user to an other app that makes the hard work, like camera resources or google drive or even the google lens. You Can search more and find the solution for your specific problem in those links. https://github.com/zxing/zxing/wiki/Scanning-Via-Intent

The Facebook app shows the recent photos that you've taken.
Because the NativeScript Api's are able to use the Filesystem api and the Camera, I'd guess it is possible to get the recent taken photos in NativeScript also.
Anyone that can point me to a good blog/documentation that makes me able to do this?

I am working in iOS and Android app that play 2D Panoramic video player.
We find an Open Source iOS 2D Panorama Video Player app
But we can't find any open source library for android.
Please suggest any open source android 2D video player to achive this.
As your question is 3 months old by now, you probably found it (or something else) yourself.
However, as other people might still be searching for it: gvr-android-sdk is Google's SDK for various VR-usages. Take a look at the simplevideowidget-sample included in the SDK.
There is also an iOS-Version available.
I have a question regarding the communication between two apps in Android. Below is my question,
Let's say I'm watching a video using any mobile browser or a native android app. Firstly, Can I Use something like an snipping tool (or an alternative tool) to crop a persons face in the video (and this should not send my video running application to background)? and Secondly, Can I send the cropped image to another native android app (my own created app) running in the background?
Is this possible, please let me know.
First of all you need to download the video you are watching and then you can edit/crop video but while editing your video player app will go in back ground.
And yes you can definately share video with other app, for that you ca nuse MediaStore class.

I'm trying to develop an app on Android and I would like to know if it's possible to build a video with photos.
I actually have several pictures (Bitmap), and I would like to create a video (programmatically) by animating these pictures I have. At the end, I would have a video file..
Is that even possible?
Yes it is definitely possible in android and can be achieved in two ways.
First and most common one, that most of the apps in android follow is to let users select certain images and then upload them to a server where you can use any video maker tool to create your desired slideshow and then send the video back to user's phone by provide a download link.
Second method is to create the video locally on the device which would require a native library like ffmpeg compiled for android which provides basic functionality of creating video but it doesn't provide any way to apply transition effects between images for that you can use another library ImageMagick. you need to have knowledge about NDK for this
