I tried testing my app on Android Studio but I was getting stuck at
"waiting for AVD to come online..." I've read resetting adb from Android Device Monitor will do it, and it did...
for 1 test, when I've restarted my PC the next day I'm getting not only:
"waiting for AVD to come online..." but also
"Could not automatically detect an ADB binary." error every time I try testing my app.
Maybe worth mentioning when I did that 1 test, I was also getting the
"Could not automatically detect an ADB binary." error, but at least it worked.

Just open the emulator and click on the three dots on the last of the toolbar line, the other page will open then go to setting, then there is the the option "USE DETECTED ABD LOCATION" just off that than the option will come click on that and select adb.exe the location of adb.exe is go to your main disk location example my main disk location is C:\ just select your own disk where your windows, mac, linus is installed,then go to users, then AppData, then Local, then Android then select sdk then platform-tool and select adb.exe then click ok
From my experience this is because the AVD can't detect your ADB binary. When you launch the AVD if you go into settings, it's the '...' symbol on the toolbar of the virtual machine, then go to the 'Settings' section there should be an option called 'Use detected ADB location' switch this off then select the location of your adb binary. In Linux you can do this by typing the command:
which adbSelect the location shown in the settings. Once you've done that the error should stop appearing.
This error because android studio did not find adb.exe in SDK\platform-tools folder. Maybe this is caused by sdkmanager while trying to update current packages.
Any way, the easiest way to fix this error is by downloading SDK Platform Tools as zip file from https://developer.android.com/studio/releases/platform-tools.html , unzip it and replace the current platform-tools folder in SDK folder.
go to ..\AppData\Local\Android\Sdk\platform-tools and reinstall your ADB, i guess this happens on ADB 32 in an system 64bits
Go and check your sdk/platform-tools, is adb there? If not Open SDK manager and download Android platform tools, contains adb.
After that try once again, for me this works
On my device (Windows 10 x64) it is located at:
C:\Program Files (x86)\Android\android-sdk\platform-tools\adb.exe
Click on the ... in the emulator and click on settings -> "User detected ABD location" will be switched on. Change it to off and browse the location of adb.exe under platform tools.
- download platform-tools from :https://developer.android.com/studio/releases/platform-tools
- Extract files and
- copy platform-tools folder to location :C:\Users\User-Name\AppData\Local\Android\Sdk
- overwrite all files
I'm remaking the selected answer. I tried to edit it myself but the editing queue is full. Here it is, for the sake of clarity.
Follow these steps:
- Open the emulator and click on the
three dotsat the bottom of the toolbar line. A new window will open (theExtended Controlsof the emulator). - Then select the
Settingstab. There, toggle the option `Use detected ABD location" off. - The folder selection for that field will turn on. Open it, and select the
adb.exefrom its current location. - That executable should be somewhere in your main disk (this will vary depending on your actual OS, either Windowx, Linux or macOS). Go to
users>AppData>local>Android>sdk>platform-tools> selectadb.exefile. - Click
Openin the selection window. The full path to the file shoulb be visible. Lastly, close the emulator'sExtended Controlswindow. Done!
