Hi,
I’m trying to compile android apk, but I get the error “No installed build tools found.”

$ ionic cordova build android

Error:

I try:

ionic cordova platform remove android
ionic cordova platform add android

After all this, I installed all the SDKs from Android 4.3 and all Android SDK build-tools from 19.0.3, but even this did not help.

any ideas?
