A young friend of mine would like to push a game created using www.buildbox.com to his Samsung Android Tablet. He is using Windows 10 and Android Studio 3.6.1.
But the Device Drop Down is greyed out and for some reason the AVD Manager, the SDK Manager and the Connection Assistant are missing from this tools menu.
On my Android Studio 3.4 I can still see the Connection Assistant
I checked the Release notes but could not find anything.
https://developer.android.com/studio/releases
I checked that Windows can see the tablet as a USB device and the friend told me that developer mode is enabled.
Any ideas what is going on ?
So I got a chance to look further into the problem.
It turned out, that the problem seems to be with Buildbox not generating a proper Android project. In particular the generated project is missing a proper module and a proper app configuration. Once I added those the missing connection tool reappeared.
However I still got an error.
I am trying to opening Profiler but it's not working as it stucks in loading, I have Android Studio 3.3.
Profiler stuck in loading
I am using this real device..
If your platform-tools's version is 29.0.3 on Android Studio 3.5, please rollback version to 29.0.2.
I found it in google issue tracker
https://issuetracker.google.com/issues/140822450
I can confirm that downgrading to version 29.0.2 fixed the issue of not founding devices in the Android Profiler. You can download that version from here: https://dl.google.com/android/repository/platform-tools_r29.0.2-darwin.zip. Unzip it in your Android SDK folder.
Click on the '+' (see image) signal!
This worked for me on Android Studio 3.5.1
with platform-tools's version 29.0.4
For me it was also showing the loading gif but just click on the '+' button and select your android!
I had the same problem for Android Studio 3.5.3, but I used a device on android 8.0, which is supposed to work fine with profiler, unlike 4.4. What I had to do was to update the platform tools from 29.0.2 to 29.0.5 and it finally started to work. You can find it in Tools - SDK Manager - Android SDK
that's because the profiler doesn't work with API 25 or lower levels.
when you are trying to start profiler you should see this message from Android Studio
or you can check the Event log, and you'll see this message
Startup CPU Profiling: Starting a method trace recording on startup is only supported on devices with API levels 26 and higher.
so all you need is to change the phone which you are working on but be Ensure that have API Level 26 or higher.
when you change the API to higher one Ensure to do these Steps:-
disable instant Run from File > Settings > unmark enable instant run...
Enable advanced profiling from app > Edit Configuration > profiling > then mark on "like the image blew" ...
Enable Advanced Profiling.
Start Recording CPU Activity on startup.
NOTE: YOU WILL FIND " APP " ON THE TOOLBAR.
finally, plug in your new device which has a higher API and start working on your app.
I faced the exact problem. Because I tried to use Profiler in lower API level of Android. In my case it was API level 19 (KitKat).
Pre-Lollipop devices aren't supported by Profiler
Use the later (>21) or latest version of Android Devices for Profiling App
It worked for me.
I had the same probleme, i fixed it by changing the targetSdkVersion to the version of my phone.
I had targetSdkVersion to 29 and the profiler wasn't loading.
Then i changed it to 28 that is my phone sdkversion then it worked fine.
I am using Windows 10 and when I launch the Virtual Device Emulator in Android Studio I keep getting the message which reads:
"The ADB binary at C:\Users\siviw\AppData\Local\Android\Sdk\platform-tools\adb.exe is obsolete and has serious performance problems with the Android Emulator. Please update to a newer version to get significantly faster app / file transfer".
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. dkalev's answer is correct but not very descriptive for a new user. I have outlined the steps below.
Double Shift to open the search box
Type SDK Manager
In the results shown click "SDK Manager"
In the window that opens click the second tab "SDK Tools". You should see that there is an update available for SDK Build-Tools on the first line
Check "Show Package Details" in the lower right hand corner
Scroll to the last (latest version) item under "SDK Build-Tools" and check the box. (Mine was 28.0.1)
Click "Apply"
In the dialogue box that pops up, click "OK"
When the installer finishes, click "Finish"
Uncheck "Show Package Details" and look at "Android SDK Build-Tools" (first line). There should be no update available and it should say "Installed"
Click "OK" to close the SDK Manager
For me, update SDK doesn't help. I solve this problem by unchecking the emulator option "Use detected ADB location". Give it a try.
I had the same problem and solved it by updating the Android SDK Build-Tools. Open the SDK manager in Android studio (double shift and type SDK manager). Then on the second tab (SDK Tools) update the Android SDK Build-Tools and the error message should go away.
This is an years old bug.
Check your adb version like this : (the adb path is given with the error itself)
C:\Users\<your_user_name_>\AppData\Local\Android\Sdk\platform-tools\adb.exe --version
output :
Android Debug Bridge version 1.0.41
Version 29.0.4-5871666
Installed as C:\Users\sunil\AppData\Local\Android\Sdk\platform-tools\adb.exe
It means this adb comes from the latest sdk platform tools 29.0.4.
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.
Just opened Android SDK Manager Then it showed 4 Updates Available. 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. I opened the Virtual Device Manager and realised my emulator was running API 27. Checked back in the SDK Manager and I didn't have API 27 SDK Tools installed at all. 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. And, in my case I need Android SDK Platform 29 because I am using react native 0.63 and Android 10 (Q). I had to uninstall Android SDK Platform 28 because it was the one that caused the warning.
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
Uncheck Android SDK Platform 28 (OBS: for me) and Apply
Click OK and Finish.
With this I was able eliminate the warning.
I had the same problem and solved it by updating the Android SDK Build-Tools in Android Studio.
step 1 - Double shift and type SDK manager, this will open the SDK manager
step 2 - Then on the second tab (SDK Tools), update the Android SDK Build-Tools and the error message should go away.
if this does not resolve check the option in Setting tab,use detected Adb tool in Setting tab
(You mentioned you are new to Android Studio) so I recommend pressing the Android Studio > Help > Check for updates... button that will update your environment.
I solved this error by uninstalling two older SDK build tools versions, leaving only the most recent one.
The solution that worked for me -
I closed my Android Studio.
I visited this site - https://androidstudio.io/downloads/tools/download-the-latest-version-of-adb.exe.html
From there I downloaded the latest adb.zip file
I unzipped the folder and copied the 3 files -
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
I went to the folder - C:\Users\PayelSenapati\AppData\Local\Android\Sdk\platform-tools
There I replaced the old files by the new files. (Paste followed by replace the existing files)
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. In my case, it was the Android SDK Tools.
First you need to check which SDK your Emulator is using and as #kuya suggested you need to follow those steps and install the latest version of that SDK Build Tool. Suppose your Emulator uses SDK 27 then you need to install latest in that series. For me it was 27.0.3. After that the error was gone.
Try factory reset to virtual device from Android Device Manager
None of the top-voted answers worked for me, except when I unchecked "Use detected ADB location" as mentioned above by #褚阳光. 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. it works for me
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. The answers of #Kuya and #褚阳光 worked for me. 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. Because with this error I was facing BSOD - https://www.techclassy.com/fix-hypervisor-error-bsod/
I faced the same issue, and I tried following things, which didn't work:
Deleting the existing AVD and creating a new one.
Uninstall latest-existing and older versions (if you have) of SDK-Tools and SDK-Build-Tools and installing new ones.
What worked for me was uninstalling and re-installing latest PLATFORM-TOOLS, where adb actually resides.
I got this error and I tried all the possible solutions that I found on every site, nothing worked.
I was working with flutter, and the command flutter doctor showed me that I need to accept a few agreements
I did that and ADB started to work
So conclusion:
If nothing works, install flutter, run flutter doctor, execute the commands that flutter doctor suggests to you. This should solve your problem
the command was: flutter doctor --android-licenses
I followed the answer, but the magic final step was deleting the existing virtual environment and creating a new one.
I've got a Xamarin Forms solution with iOS and Android projects. The iOS side was working, I switched over and did a bunch of work on the Android side. Now I need to do some more iOS stuff (push notifications) and I can't get the iOS Simulator to kick in. Xcode is installed, VS says it can see the SDK. I can open the simulator from XC but inside VS no matter what Debug combination of the .iOS project I select all I get is "Generic Simulator". Any ideas?
Try Unload the IOS Project and Reload and Set as a Startup Project, it works for me
See the answer in the comment provided by #lowleetak:
Is the minimum supported version in Info.plist less than or equal to
the version of iOS Simulator that you have?
This was the issue. The project settings listed 10.2 as the target SDK but the info.plist file had 10.3 which wasn't installed on the machine via Xcode. The machine has Xcode 8.2.1 and iOS 10.2 installed.
Additionally there's now a bug opened about this behavior. If the two fields are going to allow different values there should at least be a warning next to them about the mismatch.
I also showed Generic Simulator only on my project after updating to XCode 14 early. At the release of XCode 14 the stable Visual Studio for Mac (Xamarin) release did not yet support this version of XCode. Even the preview channel was not yet ready. Guidance from Xamarin.iOS discussion group was that the special XCode14 channel could be used to evaluate. https://github.com/xamarin/xamarin-macios/issues/15954
We have a 4 year old MonoTouch application, now a Xamarin.iOS application. It has a tag in each project
<MtouchSdkVersion>3.0</MtouchSdkVersion>
In the list of warnings with the current Xamarin.iOS and Xcode 6.1.1, I see
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: Warning: The iOS SDK version '3.0' is not installed. Using newer version '8.1' instead'. ({myProjectName})
I could manually update this tag or remove it. I do not see in the Xamarin Studio where to configure this on each project. Thanks much.
That should map to the Project options, Build, iOS Build, General, SDK version combobox.
If not found it could show you Default (not sure about the logic) but, beside Default it will only let you select the SDK that the presently configured Xcode provides (e.g. for Xcode 6.1 would see 8.1 for device builds).
note: it's possible it was left over to that value during the project's conversion to unified (which implies switching to msbuild).
