Any idea why returns me this error when i try to use ionic cordova run android?

解决方案

Search for "edit environment variables" in start. and under user variables add a new variable with name "JAVA_HOME" and value with path_to_jdk_bin.

like this

Now under system variables, the path variable should contain(add if not added) the entry %JAVA_HOME%.
