Show SQLite tables from the Android command line shell (adb)

Android/SQLite FAQ: How do I show a list of SQLite database tables from the Android command line (adb shell)?

You can show a list of SQLite tables by starting the Android adb shell (command line tool), and then properly invoking the sqlite3 command. Here's an example of how this works, with comments shown before each command:

-- first, start your android emulator

-- next, start the android adb shell:
$ adb shell

-- use the sqlite3 command to connect to your database.
-- in this case my database is named fptracker:
# sqlite3 data/data/com.devdaily.fptracker/databases/fptracker.db

-- show the sqlite database tables:
sqlite> .tables
android_metadata  projects

-- show the schema of the 'projects' table:
sqlite> .schema projects
CREATE TABLE projects ( id integer primary key autoincrement, name text not null, type text not null, description text );

-- exit the sqlite3 command line tool:
sqlite> ^d

-- exit the adb shell command line tool:
# ^d

-- i'm now back at my regular command line:
$ _
