Unable to locate the Android build tool for Ionic2 Cordova development

As I attempted to create an APK using

ionic cordova build android

I suddenly encountered the following error message:

  * What went wrong:
    A problem occurred evaluating root project 'android'.

No installed build tools found. Install the Android build tools version 19.1.0 or higher.

Despite having android build tools from various versions of Android Studio (2.1.1 - 22.0.0 - 23.0.0) and the latest version 26.0.1, this issue persists.

Here is the output of running cordova requirements:

Requirements check results for android: Java JDK: installed 1.8.0 Android SDK: installed true Android target: not installed android: Command failed with exit code ENOENT Gradle: installed /Applications/Android Studio.app/Contents/gradle/gradle-3.2/bin/gradle Error: Some of requirements check failed

The AndroidManifest.xml file shows the following uses sdk information:

    <uses-sdk android:minSdkVersion="16" android:targetSdkVersion="25" />

Installed platforms: android 6.2.3

Have you ensured that your Android SDK folder is included in your environment variables?

Make sure to include the root Android SDK folder (such as C:\android-sdk or 

C:\Program Files (x86)\Android\android-sdk\
) in both the ANDROID_HOME and ANDROID_SDK_ROOT environment variables.

Additionally, add (or adjust to match your current Android SDK folder):

C:\Program Files (x86)\Android\android-sdk\tools

C:\Program Files (x86)\Android\android-sdk\platform-tools

And perhaps:

C:\Program Files (x86)\Android\android-sdk\build-tools\26.0.1

Add these paths to your system's PATH variable.

Next, download only the binary for Gradle from here.

  1. Extract it to C:\Gradle. For example: C:\Gradle\gradle-3.5
  2. Add 
    C:\Gradle\gradle-CURRENTVERSION\bin
    to the PATH variable.

After completing these steps, restart your computer or reopen any terminal where you are running commands.
