I want to implement an automatic call from my android phone. If I set message for a particular number and date as well, then my android phone should call that number automat
Yes it is possible. The code for call is straight forward.
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:09999"));
startActivity(intent);
Use your number in place of 09999.
Don't forget to specify the permission to call in Android Manifest.xml
Create an Alarm that will be fired at a particular time and add the code to call any particular number. Here is how you can set the AlarmManager to fire at a particular time. Then you can just call Intent.ACTION_CALL when your Alarm is fired.
Yes you can, with Intent.ACTION_CALL.
