Hi every one,
I have made a widget which shows some useful sentences for life every hour.
the problem is that I cannot pass typeface to the widget(BroadcastReceiver sublcass).
I searched a lot but I did not achieve any solution.
for example I used custom textview(class which extends TextView), but the widget did not run.
and then I found "font to bitmap" conversion method, but I did not work again.
any help would be appreciated.
