• Android使用命令行操作数据库


    所有的应用程序本地文件都存放在/data/data/目录下

    C:Users
    icole>adb shell
    * daemon not running. starting it now on port 5039 *
    * daemon started successfully *
    
    N555J:/ $ su    ($只是普通用户,su命令切换到超级用户#)
    
    N555J:/ # cd data/data
    
    N555J:/data/data # ls

    查看Media数据库

    N555J:/data/data # cd com.android.providers.media
    
    N555J:/data/data/com.android.providers.media # ls
    cache code_cache databases files shared_prefs
    N555J:
    /data/data/com.android.providers.media # cd databases N555J:/data/data/com.android.providers.media/databases # ls external.db external.db-wal internal.db-shm external.db-shm internal.db internal.db-wal

    查看某个数据库所有表

    N555J:/data/data/com.android.providers.media/databases # sqlite3 external.db

    查看数据库所有表的建表语句(每个SQLite数据库中都还有一个隐藏的sqlite_master表)

    sqlite> select * from sqlite_master;
