Solve Java error Application Blocked by Security Settings.

I  try to  creating a service server model and use app invertor to write an app in the android operating system, when activated, Blocks editor not found  and appear error message Blocks editor can be enabled by a message that  “Application Blocked by Security Settings”

I  use more time to find out  to solve a problem and now i can fix it  here.

1 Open Control panel> click on java

2 Click on the Security tab, scroll down the scroll bar to Medium, then click apply and ok.

That would enable the Blocks editor in App invertor then.
