Cardboard Android - android

Is it possible to focus and open up the information just like we do on click using magnet in cardboard android?
Like ray gaze in unity, is there a alternative for android?
I want to do something like the one shown in chromeexperiments

Finally solved!
In treasurehunt sample, you can find isLookingAtObject() method which detects where user is looking...
And another method called onNewFrame which performs some action in each frame...
My solution for our problem is:
in onNewFrame method I've added this snippet code:
if (isLookingAtObject()) {
selecting++; // selecting is an integer defined as a field with zero value!
} else {
selecting = 0;
}
if (selecting == 100) {
startYourFunction(); // edit it on your own
selecting = 0;
}
}
So when user gazes 100 frame at object, your function calls and if user's gaze finishes before selecting reaches 100, selecting will reset to zero.
Hope that this also works for you

Hope this helps. (Did small research, (fingers crossed) whether the link shared below directly answers your question)
You could check GazeInputModule.cs from GoogleSamples for
Cardboard-Unity from Github. As the documentation of that class says:
This script provides an implemention of Unity's BaseInputModule
class, so that Canvas-based UI elements (_uGUI_) can be selected by
looking at them and pulling the trigger or touching the screen.
This uses the player's gaze and the magnet trigger as a raycast
generator.

Android Fotoapparat library

I'm new to Android-Developement and I would like to make a Camera-app. I found this library (this is the Github page).
But I don't know how to implement a library. I followed these steps (method 2) but I'm getting an error in a popup window called 'IDE Fatal Errors'. It says: 'To investigate / fix the problem IDE wants to attach following files to the bug report. We recommend to include all the files providing maximum information. Note: all the data you send will be kept private.' Then I can select a 'diagnostic.txt'. There is a section 'file content' where 'rootsChanged' is written. I can report the whole window to Google.
The following step is to configure the 'Fotoapparat' instance. What is an instance? When I search on Google I only find articles talking about making a library.
I'm sorry if these are stupid question but I am a beginner and I would like to learn more about Android-Development. Thanks in advance for your time and help.
Add this line in your build.gradle(Module: app) file ->
dependecies {
//Your other dependencies...
implementation 'io.fotoapparat:fotoapparat:2.3.3'
}
And start using your code. Library is working fine.
EDIT - >
You need to learn basics of java.
To setup instance of the object you need to create a variable.
Hence in your case:
Fotoapparat yourVariableName = new FotoapparatFotoapparat
.with(context)
.into(cameraView) // view which will draw the camera preview
.previewScaleType(ScaleType.CenterCrop) // we want the preview to fill the view
.photoResolution(ResolutionSelectorsKt.highestResolution()) // we want to have the biggest photo possible
.lensPosition(LensPositionSelectorsKt.back()) // we want back camera
.focusMode(SelectorsKt.firstAvailable( // (optional) use the first focus mode which is supported by device
FocusModeSelectorsKt. continuousFocusPicture(),
FocusModeSelectorsKt.autoFocus(), // in case if continuous focus is not available on device, auto focus will be used
FocusModeSelectorsKt.fixed() // if even auto focus is not available - fixed focus mode will be used
))
.flash(SelectorsKt.firstAvailable( // (optional) similar to how it is done for focus mode, this time for flash
FlashSelectorsKt.autoRedEye(),
FlashSelectorsKt.autoFlash(),
FlashSelectorsKt.torch()
))
.frameProcessor(myFrameProcessor) // (optional) receives each frame from preview stream
.logger(LoggersKt.loggers( // (optional) we want to log camera events in 2 places at once
LoggersKt.logcat(), // ... in logcat
LoggersKt.fileLogger(this) // ... and to file
))
.build();
And start using yourVariableName.

play video when text is recognized AR

I am trying to develop an android app via vuforia sdk and unity.
The app should:
detect a string and as soon as the string is detected, will play video on video prefabs (not full screen).
However, I could not figure out where in TextEventHandler.cs is handling whether text is detected...
Sorry guys.. i forgot to post code..
below was what I found in TextEventHandler that vuforia provides to me...
I was guessing maybe this is handling whether the text is detected or not
// Once the text tracker has initialized and every time the video background changed,
// set the region of interest
if (mVideoBackgroundChanged)
{
TextTracker textTracker = TrackerManager.Instance.GetTracker<TextTracker>();
if (textTracker != null)
{
CalculateLoupeRegion();
textTracker.SetRegionOfInterest(mDetectionAndTrackingRect, mDetectionAndTrackingRect);
//v.SetActive (true);
}
mVideoBackgroundChanged = false;
}
Use Text Recognition instead of this method. Visit here to see how to recognize text. And load your video when the text is recognized instead.

Android drag and return to previous activity like Facebook and Google Photos

I have been finding a way to implement animation like Facebook and Google Photos. When in 2nd Activity, when dragging images the images follow and the 2nd Activity started to fade out and we see 1st Activity. Images of what I was trying to ask is here.
Was you able to find a full fledged solution for this ?
https://github.com/nickbutcher/plaid , It might give clues to entry transition and how that was accomplished . So it might help you there. But how about when you want to drag and dismiss that activity?
https://github.com/Commit451/ElasticDragDismissLayout , Its an interesting library. Does do drags . But doesn't remember the position where the thumbnail where it was launched from. Only handles 1 swipe direction and dismisses by sliding to the right. So its not that close to what they do in 2017 Jun Google Photos Android application. You might have to modify it.
If anyone knows a better solution to this please do share.
I have found some code from Nick Butcher sample code.
ElasticDragDismissFrameLayout.java
and when using it:
chromeFader = new ElasticDragDismissFrameLayout.SystemChromeFader(getWindow()) {
#Override
public void onDragDismissed() {
finishAfterTransition();
}
};

play-games-plugin-for-unity - show specific Leaderboard

I'm trying to integrate the google play Leaderboard with help of the play-games-plugin-for-unity plugin into my game.
It works fine, committing to Leaderboard an all, only one thing is not working. When I call the Leaderboard
//LEADERBOARD
if (GUI.Button(leaderboardButton, "Leaderboard"))
{
((PlayGamesPlatform)Social.Active).ShowLeaderboardUI(Constants.LEADERBOARDID);
// Social.ShowLeaderboardUI();
}
it opens the window where I see all leaderboards. But I'm giving a specific id. This would be the behaviour I expect from the line Social.ShowLeaderboardUI(); which is commented out. The overload with a given Id (hid behind Constants.LEADERBOARDID) should start the specific Leaderboard UI according to the doc. Someone knows if this is an issue (haven't seen any report on GitHub) and how to solve it? It isn't that that big of an issue, but one click is better than two.
I tried something interesting. I changed the Id to some wrong value. Still the same behavior (opening the window with all leaderboards). Of course committing the score doesn't work anymore.
Okay, i found the error in the sourcecode of the Plugin, fixed it and resolved the problem. So here I present the fix if someone needs it. It's in the LeaderboardManager class.
This is how ShowUI is called:
internal void ShowUI(string leaderboardId, Action callback) {
Misc.CheckNotNull(callback);
C.LeaderboardManager_ShowAllUI(mServices.AsHandle(), Callbacks.InternalShowUICallback,
Callbacks.ToIntPtr(callback));
}
This should be the correct version
internal void ShowUI(string leaderboardId, Action callback) {
Misc.CheckNotNull(callback);
C.LeaderboardManager_ShowUI(mServices.AsHandle(),leaderboardId, Callbacks.InternalShowUICallback,
Callbacks.ToIntPtr(callback));
}
}
See the difference? C.LeaderboardManager_ShowAllUI instead of C.LeaderboardManager_ShowUI is called.

Android TV PlaybackControlsRow

So building a new app specifically for the Android TV interface (lollipop leanback) and I'm using the PlaybackOverlayFragment that is provided by the framework which has a PlaybackControlsRow with all the usual controls on it.
The problem is, the default behavior is for the user to have to click the "Play" button to start the video and I want it to start automatically. That part is easy and I have it working but then the Play/Pause icons on the provided control are out of sync (showing play when should be pause) because the item was started outside of the events of clicking on that control.
Documentation is sparse on these framework elements and examining the class I can't find any public method that would allow me to put this control in the proper "mode" or tell it to display the play or pause icon myself.
Anyone with experience with these yet that would know how to do this?
In order to change the state of the button, even after adding your Actions to the Adapter, you'll need to notify the changes to the adapter that has your Action.
mPlayPauseAction.nextIndex(); // next index, if it was pause, it'll be play
notifyChanged(mPlayPauseAction);
// where notifyChanged(Action action) is:
private void notifyChanged(Action action) {
ArrayObjectAdapter adapter = mPrimaryActionsAdapter; // reference to your adapter
if (adapter.indexOf(action) >= 0) {
adapter.notifyArrayItemRangeChanged(adapter.indexOf(action), 1);
return;
}
}
Well, I partially answered my own question.
If I know before the PlaybackControlsRow is created that I want to set it to the pause state (actually, playing state but showing pause button) then if I call setIndex(PlaypauseAction.PAUSE) on the PlayPauseAction before adding it to the controlsrow then it works.
It doesn't appear that I can modify it myself after adding it but that may be something else I'm doing wrong.
