I am a new developer with little experience. What do I need to update to a newer version so that message is no longer shown? I am new to android as well. I have outlined the steps below. For me, update SDK doesn't help. I solve this problem by unchecking the emulator option "Use detected ADB location".
Give it a try. It means this adb comes from the latest sdk platform tools Check the latest version from official site here. If you already have the latest version of ADB installed, and still getting the error, this is a known issue. Google hasn't yet provided any other ADB. Click on the "never show again" option and continue. This works for me. So I just Updated it and No more above warning. Had the same issue but in my case the fix was slightly different, as no updates were showing for the Android SDK Tools.
Installing v 27 resolved the issue for me. In my case what removed this message was After updating everything deleting the emulator and creating a new one. Manually updating the adb didn't solved this for. Nor updating via the Android studio Gui. In my case it seems that since the emulator was created with "old" components it keep showing the message.
I had three emulators, just deleted them all and created a new one. For my surprise when it started the message was no more. Cannot tell if performance is better or not. The message just didn't came up. Also I have everything updated to the latest emulators and sdk. This happened to me. I found this video See Here explaining the process.
Open Android Studio then click on configure. Go to SDK Manager. Go to SDK Tools and click show package details. Click OK and Finish. I solved this error by uninstalling two older SDK build tools versions, leaving only the most recent one. Then I reopened my Android Studio, opened my virtual android device.
Everything went fine. The error was no more. In the SDK Manager, in the SDK Tools tab, check if you have any updates, if not, deselect "Hide Obsolete Packages" and check if you have something marked as obsolete if so, deselect the item and apply. Suppose your Emulator uses SDK 27 then you need to install latest in that series. For me it was After that the error was gone. Fortunately, in my case though, the message didn't show up, even when I turned it back on.
In other words, the problem might be resolved by restarting "Use detected ADB location" :. Try update your SDK Tools items, and then delete all currently created emulator and recreate again. This might sound normal but I was getting the same error but just updated it and it worked now without any error.
I suggests anyone to try for updates first. If you are stuck after following each of the steps outlined in above, I will suggest you combine more than one answers. Try them out. I can explain more if the steps are yielding results for you. This can also be an issue with hyper-v settings on Windows 10 pro. I followed the answer, but the magic final step was deleting the existing virtual environment and creating a new one.
How are we doing? Please help us improve Stack Overflow. Autodetect based on host : Let the emulator choose hardware or software graphics acceleration based on your computer setup. SwiftShader : Use SwiftShader to render graphics in software. This option is typically the fastest.
However, some drivers have issues with rendering OpenGL graphics, so it might not be a reliable option. For the shortcuts to work, the Send keyboard shortcuts option in the General settings pane must be set to Emulator controls default.
To file a bug against the emulator, click Send feedback. For more information, see how to report emulator bugs. Compare the latest available emulator version with your version to determine if you have the latest software installed. You can disable Wi-Fi in the emulator by running the emulator with the command-line parameter -feature -Wifi.

Android Developers. Watch the following video for an overview of some emulator features. Requirements and recommendations The Android Emulator has additional requirements beyond the basic system requirements for Android Studio , which are described below: SDK Tools Android virtual devices Each instance of the Android Emulator uses an Android virtual device AVD to specify the Android version and hardware characteristics of the simulated device.
Run an app on the Android Emulator You can run an app from an Android Studio project, or you can run an app that's been installed on the Android Emulator as you would run any app on a device.
Double-click an AVD, or click Run. The Android Emulator loads. Run the Android Emulator directly in Android Studio Run the Android Emulator directly in Android Studio to conserve screen real estate, to navigate quickly between the emulator and the editor window using hotkeys, and to organize your IDE and emulator workflow in a single application window.
Start your virtual device using the AVD Manager or by targeting it when running your app. Limitations Currently, you can't use the emulator's extended controls when it's running in a tool window.
Snapshots A snapshot is a stored image of an AVD Android Virtual Device that preserves the entire state of the device at the time that it was saved — including OS settings, application state, and user data. Save Quick Boot snapshots When you close an AVD, you can specify whether the emulator automatically saves a snapshot when you close. To control this behavior, proceed as follows: Open the emulator's Extended controls window.
In the Snapshots category of controls, navigate to the Settings tab. Use the Auto-save current state to Quickboot drop-down menu to select one of the following options: Yes : Always save an AVD snapshot when you close the emulator.
No : Don't save an AVD snapshot when you close the emulator. Delete a snapshot To manually delete a snapshot, open the emulator's Extended controls window, select the Snapshots category, select the snapshot, and click the delete button at the bottom of the window. Load a snapshot To load a snapshot at any time, open the emulator's Extended controls window, select the Snapshots category, choose a snapshot, and click the load button at the bottom of the window.
Select Cold boot. Snapshot requirements and troubleshooting Snapshots do not work with Android 4. Snapshots do not work with ARM system images for Android 8. Snapshots are not reliable when software rendering is enabled. Loading or saving a snapshot is a memory-intensive operation.
If you do not have enough RAM free when a load or save operation begins, the operating system may swap the contents of RAM to the hard disk, which can greatly slow the operation. If you experience very slow snapshot loads or saves, you may be able to speed these operations by freeing RAM.
Closing applications that are not essential for your work is a good way to free RAM.
