Hi! I have a big problem:

When I write this:
"import android.content.IntentReceiver;" (or something other "import")
the program writes to me this: "The import android.content.IntentReceiver cannot be resolved".

And when I write something like this:
"import android.telephony.gsm.SmsMessage;" (or something other "import")
the program writes to me this:"The type SmsMessage is deprecated".

What can I do???? please help me!
