android studio platform-tools missing adb.exe

Question

Today, I clicked some update when I launch Android Stodio. I forgot what it is. Then, I run some code when there is a error "8:34 PM IllegalArgumentException: Unable to locate adb"

Then, I google for few hours and still cannot solve my problem. And I found that there is no "adb.exe" under my platform-tools folder.

Can someone help?

my os is Window 10. I have tried uninstall Android Studio and install it back. It doesn't help.

Edit 1: After I re-install the platform-tools, I get back the adb.exe.But, I run my program again, it does the "ADB initialization", my adb.exe file lose again.

Answer 1

I am writing the solution which worked for me:

• go to SDK Platform Tools;
• download SDK Platform-Tools for Windows;
• extract zip file and copy to \AppData\Local\Android\sdk\platform-tools.

Answer 2

Had the same problem. Solution was that Avast deleted the adb.exe. Try adding the SDK folder to your antivirus whitelist.

Answer 3

What worked for me (after having AS 2.x and AS 3.x installed and trying to get Canary 3.1 to work):

Sometimes during an update/trying to sideload a new version of Android Studio, the updater/patcher screws up. It might delete adb after saying it will stop and update it, it might be fastboot or aapt ... whatever.

What works for me is to delete the whole sdk/platform-tools folder, restart AS and get it to redownload the entire platform tools package.

Then start AS again and go to File->Invalidate caches/restart.

If you have been updating Java, you might also want to ensure your JAVA_HOME is correct and that your AS project has been set to the correct JDK (project settings).
