Question

获取错误：无法打开数据库＆＃34; /data/data/com.android.providers.settings/databases/settings.db"：无法打开数据库文件

当我尝试使用命令
通过adb更改移动网络时 adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db" update global SET value = 1 WHERE name =＆＃39; preferred_network_mode＆＃39;＆＃34;

Answer 1

    copy the /data/data/com.android.providers.settings/databases/settings.db 

    to my application folder /data/data/my_app_directory/.

    update the table in the database using the SQLiteDatabase class.

    copy back the database from /data/data/my_app_directory/settings.db 

    to /data/data/com.android.providers.settings/databases/
