Hi Greivin,
if you look into the 1.6 Android framework source, you see that
telephony.gsm.SmsManager is only a proxy for telephony.SmsManager.
So if you start a SDK 1.5 app on 1.6 it automatically (indirectly)
uses the telephony.SmsManager with all it's features.
Here's the snippet of the gsm.SmsManager's constructor:
@Deprecated
private SmsManager() {
mSmsMgrProxy = android.telephony.SmsManager.getDefault();
}
All the other methods are then referring to the mSmsMgrProxy to
redirect the calls. They don't have any own logic left.
If someday all phones are upgraded to 1.6 or 2.0 and you decide to
compile for these versions only, you should obviously switch to the
new SmsManager.
Hope that solves your issue,
Chris
