QUESTION
In my app I m detecting the incoming calls phone number , everything working fine but when I m trying to set the phone number in the textview of main activity I m getting below errors
Errors
...ANSWER
Answered 2021-May-23 at 17:52You never initialize the variable mainActivity
in your BroadcastReceiver
. That is why you are getting a NullPointerException.
However, the approach you are using is not good. You should never access UI components (in this case a TextView
) from a BroadcastReceiver
directly. The BroadcastReceiver
should pass the data to your Activity
and the Activity
can then manipulate the UI components. If your BroadcastReceiver
is an inner class of the Activity
, it can simply call a method on the Activity
to update the TextView
.

QUESTION
My iOS app needs Internet connection to do what it's designed to do. I don't really care how the connection is provided, meaning through WiFi or Cell service.
What do I need to include in my Info.plist
file?
I see telephony
and wifi
as options that seem related to connection. Do I need both?
I understand I can require more and tone it down later. Apple states if more capabilities added later, existing users may not be able to use the app. Another feature that I will later need is GPS but not in this version. What's the right approach to that? Do I require GPS now or later?
...ANSWER
Answered 2021-Apr-22 at 01:05No iOS device lacks networking hardware of some sort, so there is no need to limit what devices can download this app. So don't require anything. Just fail gracefully if there happens to be no Internet connection (Apple will check for this).
