hi, i am writng an appli for teasing the friends ..... apparently its a simple reminder +crush calc apllication.... but in the background it will be sending messages to other friends..... like 'crush messages', 'call me urgent', 'lets meet at the canteen' and other few customized messages.

for this i need to send sms secretely, through my application, so that other application on his device would not no about the activity ;]

i would be so thankful for all kind of help !!

First of all, thats really lame Second, its quite impossible: you need a permission to send sms, you can ask for it in your androidmanifest.xml. On installation, users have to grant this permission to the application. Personally I would not allow a "simple reminder +crush calc" application to send sms. Anyway, theres already a thread about how to send sms and quite some tuts on the inet show how to do it. If youre app would send sms, it will always go unnoticed, unless you programm otherwise. Good luck..
