I get the following two errors when i try to run my program on the AVD:
Emulator: E0630 09:34:36.670338059 9681
socket_utils_common_posix.cc:201] check for SO_REUSEPORT:

Emulator: queryCoreProfileSupport: swap interval not found
I use ubuntu 16.04 on an Hp probook 4540s
After unsuccessfully trying all my tricks, i reinstalled android studio (making sure to install it at no other place than the "/opt" directory) but the same problem still came up, however, the newest android studio at the time (4.0) with the newest gradle (4.0) came with a new feature which helped me out.
After creating a new project, instead of using the Build/play button to build the app for the first time, i used a button in the "What's new " section called Build Analyzer and after some minutes, i got the app successfully running in the emulator!
Although the app was running but the error kept been displayed on the screen until after running the app for a number of times.
the Feature is in the "What's new " (Assistant) section and can be reached by clicking: help>what's New in Android Studio scroll down the "What's new" pop up window until you see the "Build Analyzer" button then click it and wait for background processes to finish.

I'm new to Android/Kotlin programming (not to programming in general) and I'm following the Kotlin Basics course on developer.android.com.
The very first lesson after having installed Android Studio is to create a Virtual Device and run an extremely basic app on it.
However I can't get the emulator to work. The very first time I tried, it opened a small window with a progress bar but it became unresponsive at around 1/4 progress and I had to eventually kill it.
Since then it just won't start/open.
After I click run, the code compiles and the Event Log within Android Studio says Executing tasks[...] then Gradle build finished[...] and that's it. Nothing happens beyond that and the Emulator window says "No emulators are currently running".
However:
Some emulator-related processes have been started. Those processes stay alive even after closing Android Studio..
If I try to start the AVD from within the device manager, I get an error message that the device is already running
I am unable to delete these .lock files without killing the aforementioned processes
What I could find:
The Windows Event Viewer shows an Application Error
The Android Studio log file also shows an Error
I don't know what to do with either of these messages, though
What I tried
Killing the emulator processes, removing the *.lock files and trying again.
Creating a different AVD (different device, different version of Android)
Completely reinstalling Android Studio and the SDK following the accepted answer to this question: How to completely uninstall Android Studio from windows(v10)?.
None of this had any effect.
I'm running Android Studio Arctic Fox (2020.3.1 Patch 4) on Windows 10 Pro (10.0.19042 Build 19042).
I am able to run the app on my actual phone but down the line I would like to be able to test apps on different types of devices or without having to always use my physical one.
All help would be greatly appreciated.
By running and emulator.exe command in a command prompt, I was able to see yet another error message, the same one as in this post: emulator: incompatible HAX module version 3 requirs minimum version 4, and the answer to that post from user Harold Sota (as well as the comment under it from Harun, more specific to my situation) solved the issue.
I am new to Android App development.I installed Java Development Kit andAndroid Studio v 3.0.1 . There was no problem in downloading and installing Android Studio. The problem came when the time came to creat a new project. My instructor on the course told me the new project would take time to set up and configure. Mine took some 115 minutes. And after it came a Windows Alert Message mentioning that Windows Firewall has blocked some features of JDK library.
This is the screen shot of the Windows Alert Message.
Windows Alert Message
I just ignored the message, and clicked the Close button.
And when I see my newly opened project on Android Studio, I see the message that
Gradle Project sync failed.Basic functionlity will not work properly.
This is the screenshot of Gradle Error.
Gradle Project Sync Failed
I am clueless about what this Gradle is. Does this gradle error have anything to do to do with the Windows Alert Message I ignored? How can I fix this problem?
I want to create apps and just new to Android App development.
Windows Firewall automatically blocked Internet access for Android Studio and informed you about that in that dialog. Most programs, like Android Studio need Internet access, so in the future you want to click "Allow access" button whenever that dialog show up (for trusted software).
Go to Windows Firewall and in the "Allow a program or feature through Windows Firewall" option look for "OpenJDK Platform binary" and check both checkboxes.

I wish to run an application on android virtual device (I've created it). I right-click on the
Android project (which was created after I added the android environment) and choose "Run as Android Application". The emulator launches but it remains just a black window (and I wait a lot, nothing happens). Console writes "Build successful" and that's it. What might be the problem? API level is 18 (4.3). Platform Windows 7. Thanks.
Details: created a project, added hybrid application, added adaptors, deployed and run multiple times (just in browser), installed android in eclipse, added android environment, added AVD (had some old ones that didn't work, deleted them and created a new one following advises here).
It sounds like the problem is with your Android emulator.
First, can you start the emulator by itself, and see it work properly? You can start it from AVD itself. The emulator usually takes a long time to start, especially if you are running the ARM emulator instead of the x86 one.
If that works, can you run an empty Android app? You can go to File - New Project - Android Application Project, and after you create it, you should be able to run it and see an empty application.
If that works, can you try with an empty Worklight application? That way we can see if it is your specific application or something to do with Worklight.
I recently installed Android studio and the first time around AVD worked fine and the emulator was up and running no problem with that. But when I turned off my computer and booted it up again. But now when i try to open avd the following error message is displayed
when i reinstalled the android studio the same thing happens again,for the first time around it works but second time around the same error message comes.
Not able to find solutions over the internet as well.
This is a common problem that many people have faced. The Access Denied is indicating that Android Studio is trying to access files that require elevated privileges.
To solve this error, right click your Android Studio launcher, and click Run as Administrator.
I am new to Android development and Eclipse. I have been given an Android app and asked to make some simple changes to it. I can build the project and run it in the emulator, but I see some errors in the LogCat window in Eclipse.
I put aside the app I was given and wrote the Hello World app, following the Hello World tutorial on developer.android.com. With this simple app, I was surprised to see many errors and stack dumps in the LogCat window. I closed Eclipse and re-launched it. After waiting for Eclipse to finish initializing, LogCat was empty. Then I started the Hello World app by clicking the run button. After a while entries appeared in LogCat, including many errors.
With such a simple app, copied from the tutorial, I am guessing the errors arise from the development environment and/or virtual device rather than from the app itself, but I would like to be able to run apps without errors.
Is it a reasonable expectation to be able to run Android apps from Eclipse on an AVD without any errors? Or is it the state of the art that the development environment logs many errors and dumps stack traces even when everything is running "normally"?
If it is reasonable, I will pursue each error until I have cleaned up my environment and application. I would prefer this, as I would then know that if errors appear as I continue development, they arise from my application and must be fixed. On the other hand, I can't spend months developing Eclipse and the Android SDK. If I have to learn to live with logs full of error messages, I'll just ignore them unless something crashes.
Note that the Hello World application runs as expected - it appears to be working despite the errors.
I am running Eclipse Indigo SR2 and Android SDK ??? (I don't see a version number for the SDK - the installer is r18 and SDK Manager says there are no updates available) on Windows 7 Professional, 64bit. I am testing with Android 4.0.3.
Use either:
adb com.your.package:v
or in log cat on the side button (You may need to make this visible by pressing the button with two rectangles in it in log cat) press the plus button and then add an application filter
