accessing other apk database

[beltrao73]

Hi,

I have a person developing an apk in java for me, but I want to implement the sync module of this project in b4a. How can I have access to this apk´s database? I want to select and delete records.

Does he have to implement a service interface?

Thanks,

Ricardo Beltrão

While you can include a database in your APK file, in order to open it you will need to copy the database to a writable location. The internal storage of each application cannot be shared. However if this person moves the database to the storage card then you will be able to open the database from your program.

Hi Erel,

Can´t we share databases even if we use the same Private Sign Key for both apps?

Android security does not allow accessing other programs.

Ricardo,

If I were you, I would ask whomever is developing the APK for you to simply ensure that the APK reads/writes from a Database in public space (ie., downloads or Documents), this way you can both act upon the DB. Unless I'm missing something on what it is you're trying to do.
