As from Google I/O 2016 key note, Google has Introduced Android Instant Apps
This is pretty clear from the description that it is going to be possible to download a part of application (that is stream?) when it will be out for the developers to try it.
Couple of posts like This one quotes about Instant Apps :
While this is different from Google's efforts to do app streaming inside search, it's in the same spirit — and gives Google similar access to previously walled-off data inside apps.
I am wondering how it is different from app streaming if the app is going to be installed partially with Android Instant Apps?
Any additional information about this new leap in android development will be helpful.
A module of the app gets downloaded inside a sandbox. As the user navigates to the boundaries of the app more app modules will be downloaded. You as a developer will need to determine when to prompt the user to download the full app. Note that the app state inside the sandbox will not automatically be transferred over when the user downloads the full app. Furthermore, whilst the instant app module(s) will be cached inside the sandbox there is no guaranteed persistence.
Android Instant Apps enables native Android applications to run in response to launching a URL, without installing the app. Instant apps can use many Android APIs and you use Android Studio to build them.
How do they work? When Google Play receives a request for a URL that matches an instant app, it sends the necessary code files to the Android device that sent the request. The device then runs the app.
Note: Android Instant Apps only work on Android devices running on Android 5.0 (API level 21) or higher.

I am looking to create a 3rd party android automotive of our currently existing android mobile application. The application will not be listed on the play store it is just for internal use. The issue that I am facing is that the SDK is limited and it seems that I can only create applications from a set of templates (Navigation, Media, Messaging). My mobile application uses its own custom map and functionalities. I checked that people used to create 3rd party apps before but google revoked access to this 3rd party sdk and that I have to ask google for access.
Can I make any apps for Android Auto?
Also, by going through the docs it's stated here "In order for your app to run on a real head unit (not the desktop head unit we provide), your app must be distributed through the Google Play Store."https://developer.android.com/training/cars/apps/auto#car-head-unit
If anyone can shed light on this whether custom apps are possible now for Android Auto and whether we have to go through the play store in order to use the app in a real head unit.
There are some issues with the wording of this question, so let's first clarify the differences between Android Auto and Android Automotive.
Android Auto is basically the projected mode. This means apps run on your phone and show on the head unit display (assuming your phone is connected to the car head unit).
Android Automotive is referred to the embedded mode. It is actually Android running as an independent OS in the head unit of the car.
So, with this in mind:
if you want to add support for Android Auto to your existing app, you can do so by using the androidx.car.app library. It provides you with some templates to build the UI/UX. This is the only way to get your app published on Google Play and distribute to other users. Even if you don't want to distribute the app on Google Play, I believe using templates is the only way to build an Android Auto app at the moment.
If what you want is to target Android Automotive, I bet you can run your current mobile app in the Android Automotive emulator. Again, here the only way to publish your app on Google Play is by relying on androidx.car.app. If you build your own UI without using those templates, your only possibility at the time of writing is to distribute it via third party app stores (or convince Google, ;p).
Last time I've heard about running android app without installing it.
Like "demo app" or something like that.
What doest it mean?
Generally you have to go to Google Play in order to install the app and run it.
It isn't via a browser, because you can supposedly use the android app functions
Instant Apps are the next step in app evolution, a universal Android solution that brings the speed and power of a native app with the ease and immediacy of a web app. They look and operate just like one of the apps that are installed on your phone, but you don’t need to download anything.
Android Instant Apps allow you to use native Android apps in a form that doesn’t even require installing. Which means the users get to experience interactive and smooth interfaces with the tap of a finger.
Note: Android Instant Apps only work on Android devices running on Android 5.0 (API level 21) or higher.
For further info about instant apps you can refer to following link
https://developer.android.com/topic/instant-apps/overview.html#apps-features
An instant app is a portion of your app that will be executed in response to an Url. This was introduced by Google year.
Google play store will download the code necessary to execute the task it is supposed to and it will dispose of the code after the user is done.
You would create an Instant apps if you mean to provide specific feature of your app that does not require the user to download the full app. Ex: watch a video on vimeo by clicking a link on social media
This apps are built using the same process you would use to develop a regular android app but instead of developing all of the features in the same module you divide the features in different modules.
This modules should be very small and have a size limit of 4MB.
Instant apps are currently limited to a few countries, so if you are thinking of developing one and putting in production check the link below for this information and others documents on how to get started.

It's Instant App.
Here you have Google documentation
I've run a hello world instant app on an emulator following this Google's tutorial.
Everything worked well, I got the dialog asking for permission to enable instant apps and clicked 'I'm in'. After that, I could also see that instant apps were enabled in Settings > Google > Instant Apps.
But when I open my browser, run a search and click on links from websites that already have published instant apps, such as BuzzFeed, NY Times Crossword and Wish, they just open the regular web page.
I found out those apps watching Google IO 16 and 17 presentations about instant apps. I even tried the link https://www.buzzfeed.com/tasty, featured on this keynote, to no avail.
I suspect that's due to the fact that the current supported emulator doesn't come with Play Store built-in.
I'm also in a country(Brazil) where Instant apps are not supported yet according to this list. But I'm not sure if that impacts on the emulator.
Does anyone know if those are indeed the reasons why I can't check out instant apps already published on Play Store?
Since Brazil is not currently in a list of Android Instant Apps supported countries, this feature is turned off on the real devices, but emulators can still be used for Instant Apps development and testing.
Production level applications, like BuzzFeed, can be launched through Instant Apps only in countries from this list: https://support.google.com/googleplay/android-developer/answer/7381861#production. In all other countries, Instant App URLs like https://www.buzzfeed.com/tasty will proceed to the website, regardless if you’re using a real device or an emulator.
There are possibly two reasons. I recommend following the guide here to set up your emulator. Once you've confirmed that instant apps is enabled successfully via adb shell pm list packages | grep "com.google.android.instantapps.supervisor" and it is enabled in Settings->Google->Instant Apps, then try sending the link as an email to the emulator.
I've found that clicking links within the browser will often times keep you in the browser. But opening the link from Gmail always works for me. I've just checked that it works with Vimeo not too long ago - https://vimeo.com/190063150.
I believe you can't have instant apps for any arbitrary link due to DAL verification. It should be the link of the domain that you own.
https://developer.android.com/topic/instant-apps/getting-started/index.html#app_links
For instant apps, you must set the android:autoVerify attribute to true in all elements. This attribute tells Google to verify your app link with a Digital Assets Links (DAL) file that is hosted on your website and prevents apps from linking to domains that they do not own.

How will the Instant app affect the already existing app ? When its out in the market does it mean that all the existing app must be made compatible to be behave like instant app ?
Does anyone has any idea if these could be integrated with the Hybrid apps?
Will it be using the run-time permission mode ?
What will happen to the games app and other apps that has information stored about the progress of the players and the current state ?
Does this seems to be the future of the apps? What is the actual benefit in having the instant app?
Instant Apps documentation has been published: https://developer.android.com/topic/instant-apps/index.html
Instant Apps are opened through URLs. If the app is installed, then this behaves like a normal deep link. If the app is not installed, the Instant App can be launched instead.
Instant Apps must support runtime permissions.
Android Instant Apps enables native Android applications to run in response to launching a URL, without installing the app. Instant apps can use many Android APIs and you use Android Studio to build them.
How do they work? When Google Play receives a request for a URL that matches an instant app, it sends the necessary code files to the Android device that sent the request. The device then runs the app.
Note: Android Instant Apps only work on Android devices running on Android 5.0 (API level 21) or higher.
Reference:- android Developer Instant app
As shown in Google IO 2016 about Instant App, how to enable it in our application? And at which place or how to identify the screen for which Instant app should be enabled?
On top of this how difficult it would be for an application without deep links to convert it to one?
Android Instant Apps is now open to all developers and the documentation is here
For App Links and enabling Instant Apps, watch this video from Google I/O (disclosure: I am co-presenting).
Basically, an Instant App takes your installable app and divide it into feature modules, each one has their own APKs and are accessible by URLs . To do that you'll have to make them addressable by using the Android App Links.
As of today (2016 / 05 / 19), the instant app feature is not publicably available.
You can visit an explanation page, click the "I am interested" link, and fill in the form. If your product is selected, they will help add the feature.
So far, the alternative is wait until its "polished" enough for market uses, and added to Android Studio, or Maven or any other repository, along with its documentation.
In terms of implementation it will depend on how modular your code is. Each instant app module has a limit of 4mb in size. You'll have to build some server side infrastructure if you want to persist the instant app session when the user downloads the full app.
