I take that back... It actually works without any permission as it should... File f1 = ctx.getDatabasePath(appDatabase.db); InputStream in = new FileInputStream(f1); -Jona On Sep 20, 2:19 pm, Moto medicalsou...@gmail.com wrote: When doing: //open your existing DB InputStream dbStream = mContext.getAssets().open(yourDBName); I'm not able to start reading...

So, I can actually access the database as a file copy and than restore it by moving it to the same location where it was copied from? Thanks!

AFAIK, it should work fine, so long as it is your app doing the copying, and you are not trying to use the database while copying (in either direction). -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Looking for Android opportunities? http://wiki.andmob.org/hado --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: What is the best way to backup app database to a file?
Are you right now thinking only to backup your data base on the device
or also somewhere on a remote location (PC, server)?
You could easily do a byte copy of your DB
//open your existing DB
InputStream dbStream = mContext.getAssets().open(yourDBName);
OutputStream backupDbStream = new FileOutputStream(path+name of
your backup DB);
//copy file from your existing DB to your backup DB
byte[] buffer = new byte[1024];
int length;
while ((length = dbStream.read(buffer))0){
backupDbStream.write(buffer, 0, length);
}
If you want to support backing up the DB on a remote system, you could
easily use the same mechanism.

The only way I would do it would be by reading every table to an xml
ffile but it seems soo ineficient... The data does not have to be
humand readable...
Thanks!
