Got the same problem  MacOS  Android Studio 3 6 1  SDK Android 10 0   This is the directory where Android studio is looking for adb binary     cd   Library Android sdk platform-tools     platform-tools   ls package xml  platform-tools  signing request for 3232179dce22d8a6332018729026ed39f5d5cd0b 1585090071041 platform-tools r29 0 6-darwin filelist   However  the binary is in the one directory deeper      platform-tools   ls platform-tools adb  dmtracedump  etc1tool  hprof-conv  make f2fs  mke2fs conf  sload f2fs         sqlite3 api  e2fsdroid    fastboot  lib64       mke2fs     NOTICE txt   source properties  systrace   Simply make a soft link to current directory      platform-tools   ln -s platform-tools adb       platform-tools   ls adb          platform-tools package xml  signing request for 3232179dce22d8a6332018729026ed39f5d5cd0b 1585090071041 platform-tools r29 0 6-darwin filelist   This did trick for me   P S  Adding it to the PATH does not help  I can of course run it in terminal then  but Android Studio does not pick up PATH variable from  zshrc in MacOS

I get the error message  but adb exe runs anyway  and debugging works fine   so its not a problem  apart from the error message being annoying   My best guess is that more than one process is trying to start the program at the same time

I struggled with this for a while  Tried to install uninstall various packages under the SDK Manager without success  I even deleted Android Studio and reinstall it  it did not help   I am running Android Studio 3 3 on OS X 10 14 2  At the end I tried the following   rm -rf Library Android sdk   This removed the whole sdk folder  You should run this command on your home directory in terminal   it is the default location when you open it   I then started Android Studio and it could not find the sdk  So it prompted me to download it  I downloaded a fresh SDK and everything was working normally   It might be an overkill but it worked

Finally after several hours of investigation I think I have another solution for everyone having issues with AVD Manager  Unable to locate adb    I know we have the setting for the SDK in File -  Settings -  Appearance  amp  Behavior -  System Settings -  Android SDK  This it seems is not enough  It appears that Android Studio  at least the new version 4  does not give projects a default SDK  despite the above setting   So  you also  for each project  need to go to File -  Project Structure -  Project Settings -  Project  and select the Project SDK  which is set to  No SDK  by default   If there s nothing in the drop-down box  then select New  select Android SDK  and navigate to your Android SDK location  normally C  Users username  AppData Local Android Sdk on Windows   You will then be able to select the Android API xx Platform  You now should not get this annoying adb error   HTH

The ADB is now located in the Android SDK platform-tools    Check your  sdk directory  platform-tools directory and if it does not exist  then open the SDK manager in the Android Studio  a button somewhere in the top menu  android logo with a down arrow   switch to SDK tools tab and and select install the Android SDK Platform-tools         Alternatively  you can try the standalone SDK Manager  Open the SDK manager and you should see a  Launch Standalone SDK manager  link somewhere at the bottom of the settings window  Click and open the standalone SDK manager  then install update the        Tools   Android SDK platform tools       If the above does not solve the problem  try reinstalling the tools  open the  Standalone SDK manager  and uninstall the Android SDK platform-tools  delete the  your sdk directory  platform-tools directory completely and install it again using the SDK manager  Check your antivirus chest  Sometimes the Antivirus program thinks adb exe is a virus  If you find it there please restore the file and it will start working  You can also put adb exe as a safe file in you Antivirus program        Hope this helps

If you have an antivirus  such as AVG   you can take the file out of quarantine     Click Menu   Quarantine   Check box next to the adb exe file   Arrow next to delete   Restore  But sometimes  the file will keep reappearing in the quarantine  The way to solve this is by clicking Restore and add exception  or by going to Menu   Setting   General   Exceptions   And adding something like this  C  Users Johndoe AppData Local Android Sdk platform-tools   Other antiviruses have similar equivalents of a  quarantine  that the APK file may be in

even after downloading specific required file or everything  we could face file execution error   a file execution fail could be due to following reasons  1  user permission s  inheritance manhandled   2  corrupt file  3  file being accessed by another application at the same time  4  file being locked by anti-malware   anti-virus software   strangely my antivirus detected adb  avd and jndispatch dll files as unclean files and dumped them to its vault   i had to restore them from AVG vault  configure AVG to ignore  add folder to exception list  folder of AndroidStudio and other required folder   if you are without antivirus and still facing this problem  remember that windows 7 and above have inbuilt  windows defender   see whether this fellow is doing the same thing  put your folder in antivirus  exclusion  list as the vendor is trusted world wide   this same answer would go to  Error in launching AVD with AMD processor   i don t have enough reputation to answer this question there and there
