Fabric plugin for Android Studio is not showing the Distribution Screen

I'm trying upload an apk to the beta test in fabric but no luck till now, I'm following the official documentation but I can't see the "Distribution screen" section, why?
I just downloaded the last version of the plugin and the only option is to create a new app, I won't create a new one due I already have the crashlytics configured in my app.

Click the left-top Button

How to run Android without installing the APK everytime?

Launching a project would be much faster if Android Studio wouldn't need to reinstall the APK everytime.
Is there a solution/tool for this?
Thank u all.
Use Android Instant Run.
Android Studio sets up new projects to deploy to the Android Emulator or a connected device with just a few clicks. Once your app is installed, Instant Run allows you to push code changes without building a new APK.
Check out the Developer Guide to find out more.
If you have installed the apk once then you can directly run it on the connected device using the follow option, just click the icon on the right side of run option. See the image for reference. if there is any difficulty write in comment.

cannot find virtual device on android studio 3 windows 10

I am relatively new to Android development and i recently downloaded Android Studio on my Windows 10 machine. But i am facing some problems. When i create a new project, in the activity_main.xml design tab I cannot see any virtual device. All i see is a message that says Design Editor unavailable until successful build. When I click on build,I don't see any message regarding the build in the IDE log. I have the AVD manager installed and i have also created a virtual device.
Also when i edit the RUN configuration, it asks me to select a module but in the drop down window it says no module
**Just update your repositories by clicking on install missing platforms and sync project, i hope that will help **

Android Studio keeps selecting an unusable API by default

I'm running Android Studio 2.1.2 on Ubuntu 14.04. When installing I chose to download API 24 without thinking and now it gets selected every time I start a new project. Because umake provided Android Studio with JDK 1.7, the Design View always shows an error 'Android N requires JDK 8'.
I can get past this by unchecking 'Automatically Pick Best' and choosing a lower API, but now the Design View is blank. I have to edit the xml and remove the following line;
app:layout_behavior="#string/appbar_scrolling_view_Behavior"
Now I can finally see the Activity I'm building in the Design View.
What I'm looking for is a way to stop Android Studio from always having 'Automatically Pick Best' checked and API 24 selected every time i start a new project. Is this possible? It's a pain to have to go through all those steps each time.
Android Studio installs API 24 by default there is no way around this when you first install (at least that's the way it is with my ubuntu distro - you cannot uncheck API 24 even when you choose to do custom installation settings). sudo umake android
After the install, and before I created a new project I clicked the cog to open 'Configure' which allowed me to open the SDK Manager. In here I was able to install API 23 Marshmallow and delete API 24 Android N.
Now when I create a new project API 23 is selected and the Design View works fine.

using push notification using on visual studio on genymotion

I followed the link given below:
https://azure.microsoft.com/en-in/documentation/articles/app-service-mobile-cordova-get-started-push/#optional-configure-and-run-the-app-on-android
I also built the quick start azure project as said by your tutorial.
Now that I am trying to run the app on genymotion emulator (I have installed google play services in it) the build is giving me many errors
please click on the link of the image to see the errors
PS: The process is giving build errors so using genymotion is actually not a problem
Someone please help
The error indicates that you are missing a dependency from the Android SDK. Open up the Android SDK Manager and install google play services. If you installed the Android SDK as part of the Visual Studio install, you may need to run the SDK Manager as Administrator to do the install.
