Hi All ,

This command i am using to attach mmssms db in contact provider.

db.execSQL("Attach database "/data/data/
> > com.android.providers.telephony/databases/mmssms.db" as mmssms_db;" )

when i try to run the code on target it's giving me error like :

I m gettin Error 14 : "Failed to open database file "/data/data/
> > com.android.providers.telephony/databases/mmssms.db" - unable


on simulator it's working fine. I can read all the tables from contact provider.but i dont kno why it's not working on target.

Please help me to resolve this issue. Is there anything wrong witn path or permission , or with my system images.
I am totally confused what is the problem.

I don't think you can directly access the system databases like that. For that matter, any database which is not created by your application.
For cross application database sharing we have ContentProviders.
You can use something like this to open the smsmms database

Code: Select all

Cursor cSys = getContentResolver().query("content://mms-sms",null, null, null,null);


Using this cursor you can manipulate the database.
You have more Uri's like

Code: Select all

content://mms-sms
content://mms
content://sms
content://sms/inbox
//etc


Thanks for reply.
