I've come across an SQLite database (gmm_storage.db) used by Google Maps on Android, and I'm unsure as to how the data it contains is serialised. For example:
I'm saying serialised, as from the header 0xACED it appears to be a Java serialised object. However, as I have no idea what the serialised class actually looks like, I've been unable to deserialise it.
I'm also not entirely sure it's standard Java serialisation, as I've tried a number of different tools, and Java itself, and all of them report that the stream is corrupt.
You can see some references to standard Java classes, such as java/util/Set, but also a lot of smaller references to things like 'fic', or 'vot'. I'm guessing these are either obfuscated class names, or they are part of some kind of lookup/offset table.
My other guess is that as it's a Google product, it's probably using a Google serialisation library, like GSON or protobuf, but the data doesn't look like either of those.
Anyone come across this before, or can shine some light on it?
