问题
I'm trying to deploy an android build for the app. But below error occurs in the process.
May be the issue is in gradle. But "gradle -v" command executes on cmd successfully and views gradle version. But I separately downloaded gradle files and set path variables to use gradle.
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=C:\Users\intern\AppData\Local\Android\Sdk\ (DEPRECATED)
Subproject Path: CordovaLib
Subproject Path: app
Exception in thread "main" java.lang.NullPointerException
at org.gradle.wrapper.PathAssembler.getDistName(PathAssembler.java:84)
at org.gradle.wrapper.PathAssembler.getDistribution(PathAssembler.java:40)
at org.gradle.wrapper.Install.createDist(Install.java:44)
at org.gradle.wrapper.WrapperExecutor.execute(WrapperExecutor.java:107)
at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:61)
C:\Users\intern\Desktop\ionic\MyIonicProject\platforms\android\gradlew: Command failed with exit code 1 Error output:

I'expecting to get a successful build on my android device which is connected to PC but it ends with a NullPointException error in a gradle file .

You haven't set
ANDROID_SDK_ROOT=undefined (recommended setting)
you have to set ANDROID_SDK_ROOT
Setup Your root
Tools -> Android SDK Tools
Tools -> Android SDK Platform-tools
Tools -> Android SDK Build-tools
Where is android_sdk_root? and how do I set it.?
