When we save our data in android ,we allways save them in sqlite. And the database is allways access to others.How to guarantee the security of these data.
I find some apps`database is only access to themself,and when you try to open their database,it will say ‘An error occurred while opening the database,unable to open the database file’
PS:I use ‘Root Explore’ to open the xxx.db
Root access allows the user of the device, or an app granted admin permissions to access every file on the device, so you can’t “hide” any file on rooted files.
If this db has data you want to keep secret you must encrypt it, see this project:
