SmsManager没有PDA错误

Question

I get "No PDA Error" from SmsManager .

I guess the problem is somewhere at the msg Intent , because without that setText command the program works just fine. I get this error since this new intent and the setText option.

    }
}

Answer 1

below piece of code wrong. Intent has to to created. look at this example link

  Intent msg = getIntent(); String mesaj = msg.getStringExtra("mesaj"); txtMessage.setText(mesaj);
