While trying to see the contents in my sqlite database file .db, using my Android Device Monitor to get my .db file in the database folder.
I was able to get the .db file, after which my application hasn't been running well again.
I tried uninstalling the apk file and i also tried rebuilding the application, it complains about
java.lang.NullPointerException: src == null
NOTE: I didn't make any alteration in my code. I was also trying to get it from my android studio terminal, using the root. Unfortunately for me, i wasn't able to get through that...not until i used the Android Device Monitor.
my error log.
