[android-beginners] Re: NullPointerException when trying to create TelephonyManager
Look specifically for a caused by line... Yes, in the caused by line is where I'm seeing the NullPointerException (don't worry I'm not making educated guesses). My subclassing of the Application class works, or at least it did before I added the instantiation of the TelophonyManager so I'm pretty sure there is nothing wrong in the Manifest file. The debugger was throwing some java async thread exception so I'm thinking something went haywire with eclipse but I need to do some more research as to what this error means and from what I've researched so far this is whats making it throw the nullpointerexception.

[android-beginners] Re: NullPointerException when trying to create TelephonyManager
Did some more searching and I found out that I am not getting the java async thread exception anymore but I'm still getting the NullPointerException. Anybody else know what I'm doing wrong?

[android-beginners] Re: NullPointerException when trying to create TelephonyManager
Ok, so the problem was that I was calling those methods before the application was fully created. So I did the getSystemService call inside of an onCreate method and all is well and dandy now.
