This is my ionic info

See Java is correctly installed

$ java -version
java version “10” 2018-03-20
Java™ SE Runtime Environment 18.3 (build 10+46)
Java HotSpot™ 64-Bit Server VM 18.3 (build 10+46, mixed mode)

2

Cordova (or Android tooling) only works with JDK(1.)8, not 9 or 10. Install that, then it will work.

3

do you mean JDK version 8 ?

4

As far as i know… Java latest release is still at 8 (shit i was horribly outdated)

Your JAVA_HOME is invalid: C:\Program Files\Java\jdk-10;%JAVA_HOME%\bin;

Actually your issue is most likely because of undefined JAVA_HOME in your environmental variable

Follow this instructions
https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html

5

JAVA_HOME is a valid directory i have already checked

7

Same error after installing the JAVA (1.)8 version

But now you are running a Java version that could work.

What does ionic cordova requirements say?

$ gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_161;C:\Program Files\Java\jdk1.8.0_161\bin

I see a list of directories set as JAVA_HOME. Maybe it only wants one?

13

so which one shall i remove?

14

You have 2 options. Try them and let us know which one worked.

15

both doesnt worked for me :frowning:

$ gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_161\bin

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

$ gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_161\bin

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

You posted the same thing twice.
You should probably test both paths, not the same one twice.

I’ve never used Windows, so can’t be more specific, but EPERM would seem to indicate that whatever user you are running the build as does not have write access to the build folder of the project.

now opening app on android after installing shows

Application Error

The connection to the server was unsuccessful. (file://android_asset/www/index.html)
