Hi guys… I’ve finally resolve this problem…
in my case, I updated my sdk manager (include some API`S)
run the command: “npm install -g ionic cordova”;
remove the platform: “ionic cordova rm platform android”;
remove the plugin compact “ionic cordova plugin rm cordova-plugin-compat --force”;
and add the platform this way: “ionic cordova platform add android@6.3.0”;
and everything is good again!
