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 AppDataLocalAndroidsdkplatform-tools.
