|Thanks for your answer.
I followed example and it's ok. but one thing whenenver I push the the button in first app the second app opens again. I want to make the second app open at first call. After first call, from second call how to code make the second app not to re open and just send data only?

One way of doing this would be:
  1. Create a private property in App1 called SharedData. Initialize it to a default value that you can reliably check later to determine if App2 has set it yet or not.
  2. Create a public function in App1 called setSharedData(app, newdata) which does any necessary checking before setting app.SharedData to newdata
  3. When App1 needs to call App2, check whether app.SharedData is set to the default value from step #1. If it is, tell App2 to open. Otherwise, tell App2 to just send data.
