Help syncing the blockchain

[Anna Bergin]

Issue: I have two classes MainActivity and BitcoinConfig (see below). Can someone please help me fix issues I'm having syncing the blockchain?

The AndroidManifest.xml and Build.gradle files are also below.

Errors:  I’ve attached the full logcat with the getCause info because it was hard to read on this but one of the errors is:

W/System.err: java.lang.IllegalStateException: Expected the service [FAILED] to be RUNNING, but the service has FAILED (line 50 kit.awaitSync()) 

Thanks (sorry if this is obvious)!
