无法在 MAC 上的 IONIC 4 中构建 android：离子 cordova 构建 android

Question

Unable to create build for android from Ionic 4 solution.

Command: ionic cordova build android 

Error:
Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=/Users/$USER/Library/Android/sdk (recommended setting)
ANDROID_HOME=/Users/$USER/Library/Android/sdk (DEPRECATED)

Could not find an installed version of Gradle either in Android Studio, or on your system to install the gradle wrapper. Please include gradle in your path, or install Android Studio

I have android studio installed. I manually downloaded the gradle and kept in the path as well. I have all the environment variables present. Still i have the same error message as shown above.

ENVIRONMENT VARIABLES

COMMAND: open  ~/.bash_profile

export GRADLE_HOME=/Users/$USER/Library/Android/sdk/gradle/bin
export JAVA_HOME=/Users/$USER/Library/Java/Home
export ANDROID_SDK_ROOT=/Users/$USER/Library/Android/sdk
export ANDROID_HOME=/Users/$USER/Library/Android/sdk

I tried the below link in ionic forum and many other but of no help: https://forum.ionicframework.com/t/cannot-build-android-apk-ionic-4/184154

Any suggestions would be appreciated.

Thank you.

Answer 1

JAVA_HOME environment variable was incorrect due to multiple versions installed on my machine. I pointed it to the latest version and the issue is resolved.
