I have a sample database file in my phone and would like to manage it using Please bear in mind that this is an error from a physical android device and not on an android emulator.
terminal emulator:
su
#
sqlite3 -version
3.7.6.3-Titanium (I copied sqlite3 from an app called Titanium Buckup
as suggested from my google search result).
sqlite3 mydb
sqlite version 3.7.6.3-Titanium
Enter ".help" for instructions
sqlite3 mydb "SELECT * FROM mytable WHERE info = x";
Error: unable to open database "mydb": unable to open database file.
Issue fixed: See post below.
