I tried "Hello World" mobile project following the beginner guide "Your First Mobile App ".When I clicked 'Generate and Run',a website opened.And then I clicked 'OPEN EMULATOR',I met an error:
'Missing plugin emulation support
The above method is not supported by the emulator.
In order to simulate the execution of the requested action insert a JSON object in the textarea below and select the desired action.
The callback function corresponding to the chosen action will be executed with the provided JSON object as argument.'
How can I fix this problem.
