  I'm using Bash on windows10.
  I've tried to remove and readd android platform, I've done all the suggested updates on Android Studio, but I'm stuck with this error.
  Can someone help me?
  Thanks in advance

I'm having the exact same problem. Did anyone found a fix? Thank you!

Same here on bash for windows 10.

Hi, the problem is 'caused' by windows 10's bash.
You have to keep in mind that it's a 'Bash on Ubuntu on Windows'... so if you use Android Studio on Win10 for updating all the SDKs and the dev-tools, the bash will not find the binaries (as Android Studio will install .exe binaries! we're on Ubuntu).

So, install the Android command line tools for Linux (https://developer.android.com/studio/index.html#command-tools), which include the sdkmanager, then install all the packages you need and...voilà!

I felt do dumb when I've realized that... It's nice to see that I'm not the only one who did this mistake :)

Found it myself also few days later haha.

Hey @lurainsin,

I ran into this same error using WSL as well, and installing the android sdk through Linux allowed me to build the .APK file for my project successfully.

However, I can't figure out how to test the build in the emulator through the CLI - how do you test through the emulator since WSL has no GUI? I have been trying to figure out how to run the file through the Windows emulator but have had no luck so far. The only workaround I have found is to drag the .apk file into the Android emulator running in Windows...

Are you using the emulator for Windows or through Linux?

Thanks for any help you can give me on this, I'm quite stuck!
