I can not run first app on android studio - android-studio

I installed Android Studio , but I can not run first app.
Of course, I downloaded jdk before, and then I created a new variable named JAVA_HOME ,assigned the value C:\Program Files\Java\jdk-12.0.2\bin,
and also add this to Path (using ; ).
Then I downloaded Android Stdio and installed it , intending to create my first app. But I get nothing but a blank screen with no option for running , and no simulator.
Moreover, I can see that it's syncing forever...

You should provide some image in order to see what is happening to you...

Not able to run Emulator using the Android studio for my Flutter app, getting NO CONNECTED DEVICES error

Please Note: I tried several available solutions but none worked for me since yesterday hence posting this. I have also mentioned below what are things I have tried so far.
I am new to Android Studio and Flutter application and I am trying to build a simple Flutter app using the Android Studio.
I have downloaded and kept my flutter files in C:\src\flutter. Also added to Environment variables.
I have installed the Android Studio and also installed the Flutter plugin with the Dart.
I created the Virtual Emulator Device using the Tools->AVD Manager and choose the Nexus 6 with the Android 8.1
Created a simple project using the File->New Flutter Project->Flutter Application.
When I try to run this application I get the following error:
As you can see in the screenshot it shows that the No Devices in the emulator section not sure how to run it.
Things I have tried so far:
If I run flutter doctor then I get a tick for all the things except Connect Devices. My guess is that it is obvious because I have not connected any external device but using the emulators.
I tried to create the emulators using the command flutter emulators --create Nexus_6 and tried to launch it using the command flutter emulator launch.
I tried running the Android studio as an Administrator.
Restarted the system several times.
My adb.exe was crashing so updated the windows and replaced it with the new adb.exe as mentioned in one of the solutions.
My flutter emulators show following list in the command prompt:
I tried checking the folder in Appdata -> Local seems to be fine as per other mentioned answers.
When I run the Emulator using the AVD Manager from Android Studio I see that it is firing up the Android Emulator but it is not responding. In addition to this, I also observe in my task manager that process adb.exe(32 bit) is running whereas my WINDOW 8.1 is 64 bit. Is this expected?
I am not sure If I missed something here. Please help me on how to solve the issue.
Using below command on Flutter worked for me:
flutter config --android-sdk [android-sdk-path]
The path is usually C:\Users<username>\AppData\Local\Android\sdk
this path can be found from android studio - SDK manager also.

Installation freezes at "Unzipping Dart SDK" in android studio

Recently I had installed a flutter plugin in android studio. And when I chose to create a new project, it asked me for the flutter sdk. I chose "Install SDK". It froze at ""Unzipping Dart SDK".
I left it in this state for more than 3hrs, but there has been no response.
Please can any one help me to continue....
This may be a bug in flutter (that it doesn't report a useful error), there are quite a few reports like this one in the issue tracker.
You should try running flutter doctor from a command prompt, as this will perform the same job of downloading/extracting the Dart SDK but may be easier to troubleshoot.
From the issue linked above, it seems like a common issue is permissions - having it in a location like Program Files that non-Admins can't write to and therefore you need to run as Admin for it to work. A better fix would be to not put Flutter inside a protected path like C:\Program Files.
In my case (Windows 7) i found that the flutter sdk folder permission was set to be readonly, once i changed the folder permission... it works fine

Android Studio won't run application from studio ide?

I've got an application I've been working on and am having an issue with android studio. When I click "build->run" and then select my device, the application never runs on my phone (and the log in android-studio that automatically comes up does not have anything, whereas in the past when I have used this feature it usually says something like, "waiting for phone..." and then the application pops up and automatically opens on the phone and you get some other pertinent information). I have the phone already in developer mode with the install from unknown sources set to on. When I manually move the application from its gradle build location to the phone and then install it manually in file explorer, all is well and the application performs as expected. As I need to debug, however, this is not a very viable solution. Anybody have any advice as to how to get it to run from the IDE? I have tried rebuilding and invalidating the cache/restarting android studio, to no avail.
When I click the run tab at the bottom I have an empty window. When I click the debug tab, I see:
Waiting for device.
Target device: samsung-samsung_sm_g920a-randomIntegerId
Uploading file
local path: /home/eric/Documents/class/OOSE/final_project/2015-group-17/project_code/android/Place2B/app/build/outputs/apk/app-debug.apk
remote path: /data/local/tmp/oose2017.myApp
Note: I am building the application on a LUbuntu 15.04 VM on a windows 8 host, and am using the latest version of android studio.
EDIT: gradle console indicates a successful build as well (obviously since moving the .apk manually to the device works properly).
Open 'Run->Edit Configurations...', and look for your app module in the column on the left-hand side.
Select it, then go to the 'General' tab.
Under the 'Activity' section, there are a couple of radio buttons. Make sure that 'Launch default activity' is selected.

android studio not working well not displaying packages

hey guys im not new to java but this android studio thing, im definitely not used to it,
so i just want to know what packages/tools i need to download from the sdk manager to get me started (im currently dev' apps to be run on api 2.3 gingerbread devices )
From the sdk manager this is what i did,
i downloaded and installed all the latest android sdk build tools,sdk platiform for 4.4 and 5.0
then i also downloaded the whole 2.3 api 10 since its what i was developing for....
after that when i start android studio,just right in the work space where you see the 'package' menu
i get nothing displaying,i mean even all the api i installed i still get nothing.
anybody who been using this tool can gimme help.thx
kind regards C.B!
When you open SDK manager, right click on the .exe and select
"Run As Administrator".
Don't open it from within android studio, find the exe file on your machine. Worked for me when I ran into that problem.
EDIT: You may need to download the sdk separately form here: https://developer.android.com/sdk/index.html?hl=i
Click VIEW ALL DOWNLOADS and pick the appropriate 'sdk only' download for your machine.

Wrong build being deployed on Android device using Visual Studio 2012 Xamarin.Android

I am using Visual Studio 2012 and Xamarin.Android Beta release to develop an Android application. When I try to deploy the android application for debugging purposes onto an Android device, it deploys the previously built application on the device and not the recent changes I made and deployed (i.e No refresh of build). However, if I use Xamarin Studio to do the same, it deploys the correct build everytime (i.e refreshes the build with new code changes).
Any idea why this is happening?
Thanks in advance!
I had a similar issue: With Visual Studio 2019 the debug version of my driver was deployed while building the release version.
The cause of my problem was, that in the Properties -> Driver Install -> Package Files I had an absolute path pointing to the debug version of my driver in the column File. This setting is valid for all configurations (not separated for debug/release), and when entering macros, they are immediately expanded to absolute paths.
I fixed this by editing the .vcxproj file with my favourite editor and changed the path back to $(TargetPath).
I had the same problem. My solution was to add "deploy" to the build configuration:
BUILD => Configuration Manager... => (select "Debug" from left-hand combo-box) => (tick "Deploy" in grid)
Courtesy of this xamarin forum post.
I have no idea why it does this, I had this issue before. I also noticed that the device log was somewhat behind (ie, at 3.30pm, the last record on the device log was 11.00am).
Uninstalling the app from the device and re-deploying it seems to correct it.
Note: I had this issue in VS, didn't check with XS.
I would look at the difference in your deployment settings in VS and XS (I think it may have something to do with the Fast Deployment option).
Similar question (though for iOS Simulator) here.
I had a similar problem (though on an Android emulator).
What didn't work for me:
restarting the computer
restarting Visual Studio
deleting bin / obj folders
going into Configuration Manager (Debug / Release / Configuration Manager) and ticking everything there - everything was ticked
changing the version of the app in the manifest
What worked for me?
Uninstalling the app from the emulator and then running Debug again.
It was an Android emulator, so I uninstalled by clicking on the app icon and holidng for long, and then dragging it to "Uninstall App". On an iOS simulator it should be similar.
