I'm trying to add multiple views when detecting QR code. I need to show one button, one image and one text when QR code is recognized. I use metaio SDK-Template project and for now I'm only able to show one thing at a time.
Can someone please point me in right direction?
when you use metaio for detecting QR codes you're lossing the concept of augmented reality because you are scanning for a QR code and you wont be able to set a 3d model into your target or make visible and enable view components on the UI, if you have concerns about the objective about augmented reality foundamentals check the metaio documentation and examples at dev.metaio.com.

I am writing an AR Android application in which I scan QR codes (using the Google Mobile Vision Barcode API) as a trigger and then render objects into the camera view.
As there may be more than one QR code at the same time, I want to access the location of each code on the screen, so that the objects will be rendered on top of each code. At the moment - if there are two QR codes being detected by the camera - the objects will be placed at the exact same position in 3D space.
Example:
There are two QR codes being detected by the camera, one on the left
and one on the right of my camera view. Right now, both objects would
be rendered in the center of my camera view, as this is the default
value of my app.
I want the object related with the left code to
appear on the left and the object related with the right code to
appear on the right.
I have tried calling Barcode.getBoundingBox().exactCenterX() and [...].exactCenterY() to get a rough value of the code's location, but it does not work out well. Unfortunately I can't find a more suitable method in the documentation.
I can't be the only one who needs the code's location on the screen. How did you guys do that?
Thanks a lot.
I want to capture the pointer locations in whole android device by providing a service to develop something like Pointer Location in Developer options .
First I have tried addingoverlay view which is always on top to capture the coordinates . but this method didn't let me to get touch events in move actions .
So I decided to try another way . At last I found that for rooted devices , we can get touch events but I don't know how . Could you please give some suggestions ?
thanks in advance
I have been looking for this answer as well. Can you specify how you did the overlay view and captured the coordinates?
I was able to do the overlay as well, with some other answers from here on stackOverFlow, but if I capture the Overlay coordinates, it renders the background/OS useless. Its one or the other, not an actual service in the background running or an overlay recording coords. Its one, or the other.
I have read that this goes against the Android security framework, since it would be a really big flaw when exploited. Although, everything that I have read is from 2012 at the earliest. This is the newest post in 3 years. Any insight?
Im using this library to create a gallery,and im kinda new to android programing but i want to add a listener to when the user swipe down the image it will be deleted.
thanks for the helpers,and if you didnt understood me tell me to rephrase.
Ok, since you haven't tried anything, and thus you don't have a specific question, all I can do is trying to point you in the right direction (I hope).
I suggest that you do the following:
1) Setup the library: take a look at the examples provided by FancyOverFlow.
2) Make sure that you understand what is going on about the code that you use, don't add code "just because it works". Do this as a rule of thumb for every code that you write. If you are using a 3rd party code library, you don't have to fully understand how every method works internally, but make sure that you understand in/outputs of the methods you are calling. Understanding how things work will make it much easier to modify your own code.
3) Find out which component has the hold of your current image in displayed gallery. This will be the control on which you will set up a swipe listener do detect user swipe moves. I haven't tested this, but I suspect taht in this case the component is called FancyCoverFlow (take a look at README.md file).
4) Take a look at Swipe Views (or any tutorial that does swiping) and adapt your code.
If you are new to Android, it may take a while, but don't give up!
I am creating a service application where in the person who uses the service fills his data and signs it
Now I want to create a blank page where I can take the signature of the client on the TAB itself. So please help to do this.How can I implement it.
I have refereed to this http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Paths-Creating.html link but some how I am not able to work with it.
Please help.Thanks
You can do it using GestureOverlayView. Example in the links: http://www.intertech.com/Blog/android-gestureoverlayview-to-capture-a-quick-signature-or-drawing/
Specifically, create a GestureOverlayView in your layout xml file, then in your Activity class capture the gesture and save it as bitmap image.
Go through the developer API if you want to have specific function for your page, especially for events like Gesturing or Gesture Finish : http://developer.android.com/reference/android/gesture/GestureOverlayView.html
Hope that helps
I am working on a research project.The scenario is this.
I am taking the screenshot of my desktop and then I process it using an API to get the position of a certain text on my Desktop.e.g , say I have the browser open on my desktop and I am on stackoverflow.Now I want to search the position of the logo stackoverflow on the screenshot taken.Then I want to simulate a click on it.I am using Java platform.
Now I have 2 questions:
1)Is there any free API(OCR) which I can use to process the screenshot to fetch text position (or can be done by some trick) and gives good results.
Or Any way you can suggest that I can use (instead of taking screenshot and processing it) to get the position of any text on the screen.
2)How can I simulate the click on the screen using the code by a background program running(I mean I have done it in Swing and other language UIs but this time its different as Now I want to click on the screen.
If I understood you right you want to move your mouse and click on the screen. That not that hard you could use the robot class from Java!
For example:
Robot rob = new Robot();
rob.keyPress( KeyEvent.VK_ENTER );
or what ever, there are so much bottons and movements you could with it. A list of all methods you find here.
And your other question I can't answer. I think there is no API that is able to search a text and give you the position. But what I know is that the robot class is able to capture the screen and put it into a BufferedImage. With it you could compare two pictures.
Maybe you could get use of this but I don't know if it is what you search.
