getGsmSignalStrength() always returns '99'

Question

Do to the Licensing check delivering a "Not Licensed" response with no or low connection, I have been trying a work around. I wanted to check the signal strength and if it is over 50% (15) or returns a 99 because of no connection, I want it to bypass the check until the next time the app is started with a better signal. This way no authorized user should ever see the NOT LICENSED response.

Question 1: When using getGsmSignalStrength() does only return phone/3g/4g strength or wifi strength as well. If the user is in wifi mode than it should work as well? I do know how to check to see if wifi is connected, so I can always use that to check wifi if needed.

Question 2: getGsmSignalStrength() is always returning a value of '99' even when I am staring at my phone and it is showing full strength.

The entire purpose of ConnecetivityCheck.java is check then continue. Right now I just have it automatically jumping over the check and showing Toast box with the getGsmSignalStrength() number, but this is always showing '99'.

Please Help, thank you. Below I have attached my code...

Answer 1

Question 1: It should only be GSM signal strength.

Question 2: I can't find anything wrong with your code, are you sure that you have a GSM signal? If you live in the US is more likely that you are using a CDMA network. There are other ways to get that signal strength: Link
