Is it possible to access another apps database if you have the device key?
===

I am trying to access another apps database, I know it is located in "/data/data/jp.co.xxx.xxx.framework.database/databases/SETTING". 

I have the device key and have signed my apk with the device key but I am still unable to open the database. 

Is this possible with just the device key, I do not have the shared user id?

Thanks
