在调试过程中，需要修改数据库中的数据，此时就要用到sqlite3工具，可以方便我们调试
由于在界面上无法打开“数据连接”，只能通过修改数据库来打开
下面先来看下如何修改表global中的mobile_data数据

上面的过程就把settings.db数据库表global中数据mobile_data从1改为0
下面来看下查看数据库的一些命令：
.database 查看数据库信息
sqlite> .database seq name file --- --------------- ---------------------------------------------------------- 0 main /data/data/com.android.providers.media/databases/external. sqlite>
.table 查看表名称
sqlite> .table album_art audio_genres log album_info audio_genres_map search albums audio_genres_map_noid searchhelpertitle android_metadata audio_meta thumbnails artist_info audio_playlists video artists audio_playlists_map videothumbnails artists_albums_map files audio images sqlite>
.schema 命令可以查看创建数据表时的SQL命令
