"Gradle sync failed: No installed build tools found. Install the Android build tools version 19.1.0 or higher"

Question

I'm trying to open an Ionic2 Project in Android Studio, but it gives me the following error into the Event Log: "Gradle sync failed: No installed build tools found. Install the Android build tools version 19.1.0 or higher. Consult IDE log for more details (Help | Show Log)" SCREENSHOT

I have seen a similiar problem stated before (also maybe one of the latest release of Ionic2 or Cordova broke something -> https://github.com/driftyco/ionic/issues/10604).

Changing the version of "buildToolsVersion" or "compileSdkVersion" from gradle.build file or from Project Structure didn't help.

Under "C:\Users\Gaby\AppData\Local\Android\sdk\build-tools\24.0.3", I installed the 24.0.3 build tool version.

The path variable from environment variables indicates also the path correctly

At one moment, I had all build-tools installed with "android update sdk -u -a" but again, the same error occured.

Does anybody know a suitable workaround to this issuse ?

Many thanks

You need to write the correct "Environment Variables". See: https://developer.android.com/studio/command-line/variables

Windows:

setx ANDROID_SDK_ROOT "C:\android-sdk-windows"
setx PATH "%PATH%;%ANDROID_SDK_ROOT%\tools;%ANDROID_SDK_ROOT%\platform-tools"

Mac OS X

export ANDROID_SDK_ROOT=/<installation location>/android-sdk-macosx
export PATH=${PATH}:$ANDROID_SDK_ROOT/tools:$ANDROID_SDK_ROOT/platform-tools

Linux

export ANDROID_SDK_ROOT=/<installation location>/android-sdk-linux
export PATH=${PATH}:$ANDROID_SDK_ROOT/tools:$ANDROID_SDK_ROOT/platform-tools

Update: ANDROID_HOME is deprecated, ANDROID_SDK_ROOT is now the correct variable
